Wasteful Thinking

With the weather getting colder, you might be tempted to start your vehicle up, let it idle for 15 or 20 minutes and then get in the nice, cozy cabin.  Some vehicles offer remote starting that let you do that from the comfort of your home or apartment.  But is letting your vehicle idle like that good for it?

Manufacturers say it doesn't harm the vehicle.  They say it's because modern vehicles are made differently from those in the past.  Just about all newer vehicles employ fuel injection which uses computers to adjust the amount of gasoline that goes into the cylinders.  The engine gets only the fuel it needs, taking conditions into account.

Older vehicles, on the other hand, used to use carburetors.  When you started a cold engine, the carburetor wasn't able to adjust the gasoline amount depending on conditions.  Some of the gasoline would mix with oil and the pistons wouldn't get the same lubrication as they would with undiluted oil.

So yes, you can warm up your newer vehicle for your own personal comfort.  But consider how much fuel you are wasting.  That is not only throwing away money, it's a waste of natural resources.  And it puts more carbon into the atmosphere. 

Automakers have to be mindful of what fuel economy their vehicles can achieve.  So the flip side of the remote starts they offer is a "stop-start" feature.  When you stop your vehicle, even at a stoplight, your vehicle will turn the engine off.  When you take your foot off the brake and step on the accelerator, it starts up right away.  That feature can save as much as 10 percent of the fuel your vehicle uses. 

Your vehicle may not have that start-stop feature, but you can still save fuel by shutting off your engine manually if you are waiting somewhere, like a parking lot or perhaps sitting outside your child's school waiting to pick him or her up.  It saves you money and contributes to a healthier atmosphere for our planet.

Improve Fuel Economy with Proper Maintenance at Gilmore's Auto Service in Walnut Creek

With Walnut Creek gas prices being what they are, many of us in CA are driving less and looking into purchasing smaller or more efficient vehicles. Walnut Creek area residents who have to drive a lot, have large families or need four-wheel drive are particularly hard hit by the cost of fuel in CA. But there are things all Walnut Creek drivers can do to save fuel: We can improve our driving habits and stay on top of preventive maintenance at Gilmore's Auto Service. These things make small savings possible, but they can really add up.

Let's start with driving habits. One major gas-eater is jackrabbit starts. A smooth, gradual acceleration uses a lot less fuel. It's also easier on your engine and drivetrain, so you'll prolong their lives as well.

If you drive with one foot on the brake, stop. That creates drag, increasing fuel usage and reducing the useful life of your brakes.

Slowing down can really add up on gas savings over time for Walnut Creek drivers. Driving five to ten miles over the speed limit can use up 10 to 15% more gas. The time savings is only a few minutes per hour, so the cost per minute can be rather steep.

A little extra planning can save fuel for vehicle owners  in Walnut Creek as well. Leave a little early so you have time to slow down and still arrive on time. Also, plan errands ahead of time and group them as much as possible. Driving shorter distances is a great way to save fuel.

Using your cruise control where safe can save on fuel. Check your owner's manual for guidelines on when cruise control is recommended and when it isn't.

Clean out your trunk. Every ounce in your vehicle translates to a bit more fuel required to drive around Walnut Creek.

Many Walnut Creek residents let their car warm up during the winter - a major fuel drain. Your engine doesn't benefit; modern engines don't require a warm up to get up and running, although it's best to take it easy on them for the first few miles.

Now that we've gone over a few tips for improving driving habits, let's talk about the maintenance of our vehicle. Good car care at Gilmore's Auto Service in Walnut Creek actually pays for itself in fuel savings.

First, if your gas cap is leaking or worn, get a new one.

Second, keep your engine clean. Clogged fuel filters, dirty fuel injectors and plugged PCV valves all cost you in loss of fuel. Replacing them or cleaning them will both improve fuel economy and increase the power you're getting from your engine.

Third, don't ignore your Check Engine light. Problems that cause that light to come on usually affect your fuel efficiency.

Fourth, check your 's owner's manual for service that should be regularly performed on your vehicle, and follow the schedule. Or talk to your friendly service advisor at Gilmore's Auto Service . Oil changes, transmission checks and cooling system service all improve fuel economy if they're done when needed. Low fluids and dirty fluids also create conditions in your vehicle that require more fuel. So routine maintenance is a must to maintain fuel economy and save cash.

Last, keep your tires inflated. Underinflated tires increase your vehicle's friction with the roadway, which increases the energy it takes to move. Keeping your tires properly inflated is great for saving gas as you drive around Walnut Creek.

So if the cost of gas in Walnut Creek has got you searching the sofa for extra pennies, you might want to start making a few changes in your driving habits and getting your vehicle the service it needs at Gilmore's Auto Service in Walnut Creek.

Lease or Buy?

Lease? Or buy? These are the options for Walnut Creek drivers. It's always a tough question for auto owners, but here is some info that'll help you make an informed decision.

If you buy, you'll pay the full cost of the vehicle, maybe an initial down payment, monthly payments on the balance that pays down the loan principal, and the finance charge.

Walnut Creek drivers who lease finance the portion of the cost of the vehicle that's used up during the term of the lease. You'll pay some money up front: fees, security deposit, first month's payment and maybe a capital reduction. The monthly payments include a depreciation cost and a finance charge. When the lease is up, you return the vehicle to your local Walnut Creek area dealership. 

So how do Walnut Creek drivers decide?

First, how much do you have for a down payment? A lease usually requires a smaller down payment.

How much monthly payment can you afford? Again, lease payments will be much lower for any given down payment.

A lease needs requires better credit, so that's a factor.

How long will you keep the vehicle? Walnut Creek drivers who keep their vehicles around for a while will pay less if they buy. But just two or three years? Then leasing is the way to go.

If your car might suffer a ding or two, like a work truck would, then buying's better. The auto leasing company will want their vehicle back at the lease end in tip top shape, and if repairs are needed, you'll pay.

How far do you drive in and around the Walnut Creek area? Important to consider because leases have a mileage limit; if you go over, you pay a hefty charge per mile/kilometer when the lease is up. So high mileage CA drivers should definitely buy.

Will the car be used in your business? Check with your accountant, but both financing options have different tax benefits, depending on your circumstances.

Over the short term, leasing is much cheaper. Medium term, leasing and buying costs are about the same. Over the long haul, leasing always costs more.

Leases may sound a bit complicated, and the typical lease decision weighs more on the monthly payment rather than price. So sometimes Walnut Creek leasers may pay on a higher purchase price than a buyer would.

Here is a tip: If the salesman asks if you'll be leasing or buying, say you're not sure yet. Make your best deal, then look at your financing options.

Here's another: With a buy or a lease, if you total the vehicle, you'll owe the full amount of the loan, or the balance of the lease payments. Usually, it's less than the vehicle's fair market value, and that's all your CA auto insurance company will pay. But ask your Walnut Creek agent about gap insurance, which pays the difference between fair market value and what you owe. Big consideration for a lease.

Remember, you have to return your leased vehicle in excellent condition and may need to do all the vehicle manufacturer's recommended service and maintenance or face penalties. So see your local advisor at your Walnut Creek auto repair shop  or Gilmore's Auto Service on a regular basis, get the required work done and save the service records. It's well worth it.

Commitment to Make Your vehicle Last at Gilmore's Auto Service

These days many people in the Walnut Creek area are really committed to making their cars last a long time. First thing: you've got to start with what you've got. It'd be ideal if people started with a brand new car, never missed a scheduled service item, paid attention to the severe service maintenance schedule and had regular inspections. But if you've had the vehicle for a while or bought it used, its maintenance history is what it is; and that's where you start.

Go through the maintenance schedule for your vehicle and see what's been done and when. Have your Walnut Creek service advisor at Gilmore's Auto Service do an inspection and come up with a list of stuff that needs to be done. Review the list and prioritize the work, talk about budget and make a plan to get caught up.

Making a plan is so important. Suppose you go in for an oil change and learn you need your cooling system serviced, a transmission service and are coming up on a timing belt replacement in the next 5,000 miles/8,000 kilometers. You might be pretty overwhelmed.

To make it even more stressful, these are all very important systems that are expensive to repair if there's a failure. In a consultation with your Gilmore's Auto Service service advisor, you might decide to take care of the transmission on this visit, set an appointment for the cooling system service next month and get an estimate for the timing belt replacement so you'll be prepared for it in a few months.

Having a plan for taking care of these important services will set your mind at ease.

Differential Service at Gilmore's Auto Service: Viva la Difference

Every vehicle on CA roads has a differential, and it is important to the proper operation of the vehicle.  But most Walnut Creek residents don't have a clue what it is.

The differential compensates for differing wheel speeds. For example, when you turn, the inside tire on the turn travels a much shorter distance than the outside wheel. So the inside wheel of the vehicle must move at a slower speed than the outside wheel. Without a differential, the wheels would hop and scrape while turning.

Have you ever seen the large bulge in the middle of the rear axle of a truck? That's the differential. In a rear-wheel drive vehicle, the differential is located on the back axle. Four-wheel drive vehicles and SUV's have differentials on both the front and the rear axle.

You might expect that the differential is located on the front axle of a front-wheel drive vehicle. You'd be right. But the differential is called a transaxle on a front-wheel drive vehicle because its location allows it to be combined with the transmission.

In an all-wheel drive vehicle, an additional differential or transfer case is located between the front and rear axles. Differentials are strong: They have to be because of the job they do. But those tough parts need proper lubrication. You don't want your differential to seize up. That results in damage to your vehicle.

So you need to have your vehicle differential serviced regularly. It's not a complicated job. At Gilmore's Auto Service in Walnut Creek, we've been servicing differentials for years. The used lubricating fluid is simply drained and then replaced. Some vehicles require specific additives in the differential fluid; your Walnut Creek service center will ensure you are getting what your vehicle needs.

The intervals in time or mileage for servicing your differential vary greatly from vehicle to vehicle. Check with your owner's manual or Gilmore's Auto Service service advisor to find out how often your vehicle differential needs to be serviced.

On Board Diagnostics for Your vehicle

Today we're going to talk about on-board diagnostics and the questions we hear from folks around Walnut Creek, CA, who need answers about diagnostic services. They want to know what diagnostics are, what's involved and what the benefits are. They really want to understand the value of diagnostic scans by a trained technician in Walnut Creek.

These are valid concerns. If you don't understand something it's really hard to know its value. Let's start with some history.

Since 1996, all cars and light trucks in Walnut Creek, CA, have been required to use a standardized diagnostic system to help repair technicians determine what's wrong with your vehicle. The diagnostic system works with the vehicle's Engine Control Module – the computer that controls many engine functions.

The computer monitors dozens of components and processes. Depending on what the sensors read, the computer will make adjustments to compensate for conditions and minor problems. When there is a condition that it can't adjust for, the computer will turn on the Check Engine light.

It is also called the 'service engine soon' light on some vehicles. The warning light signals you to get into your local service center so that the trouble code can be read and the problem can be fixed. Your service center will have a scan tool and powerful software that will help the technician diagnose the problem.

If you've searched for Check Engine light on the internet, you may have seen that you can buy an inexpensive scanner or go to an auto parts store to have the trouble code read to tell you exactly what's wrong.

That's a common myth. The code itself doesn't tell you what's broken. It starts you looking in the right place. It tells you what engine parameter is out of range – but it won't tell you what's wrong or how to fix it.

Let's say you think your daughter has a fever. You take her temperature and it reads 102 degrees F/38.9 degrees C. You've confirmed a fever, but you don't know what's causing it. Is it a 24 hour flu, an infection, appendicitis or leukemia? A fever is a symptom of all of these medical problems, but it takes a skilled physician's examination and additional diagnostic tests to find out what is actually causing the fever.

An example of a trouble code could be: P0133, which reads 'Bank 1 sensor 1 circuit slow response.' This means that the front oxygen sensor has a slow response time to changes in the air-fuel mix. If that's all you knew about cars, you would think your oxygen sensor was broken and would replace it. Now, it could be the oxygen sensor – but it could also be a bad or contaminated airflow sensor, exhaust leak, electrical problem, an intake manifold leak or any of a number of other things.

You can imagine a lot of oxygen sensors have been replaced because of that code. So the on-board diagnostics point the way to where the trouble lies, but it takes some skill and high-tech equipment to actually pinpoint the problem. The cheap scan tools that a consumer can buy do not have the ability to retrieve some of the operating history that's stored in the engine control computer. That history's very helpful in diagnosing the problem. Service centers like Gilmore's Auto Service invest a lot of money in high-end diagnostic tools to help solve the mystery and get you back on the road as soon as possible without replacing a lot of parts that don't need replacing.

So, on-board diagnostics provide a powerful starting place for a highly-trained, well-equipped technician to get to the bottom of your problem. When your Check Engine light comes on, get it checked at Gilmore's Auto Service. If the light burns steadily – don't panic. Get in to Gilmore's Auto Service soon to have the engine scanned. A flashing Check Engine light means that there is a severe engine problem. Get in as soon as you can – waiting too long can lead to very expensive damage.

And try to not drive at high speed or tow or haul heavy loads with a flashing Check Engine light.

Make an appointment with Gilmore's Auto Service to have your on board diagnostics analyzed.

Keep Your Walnut Creek Car Breathing Free: Engine Air Filter

Hey Walnut Creek - this is something really amazing: Your vehicle uses 12,000 times as much air as fuel when you drive it. All of that air has to be filtered to keep your engine clean.

That's like 100 gallons (380 liters) of air every block! The engine air filter is just another example of a very important but inexpensive part that has to do a tremendous amount of work. And when it works, everything goes well. But, when it doesn't, well, it can lead to problems. Of course, your vehicle manufacturer recommends how often to change your air filter. But like most service intervals, where and how you drive your vehicle in CA affects when your filter needs to be changed.

Dusty conditions around Walnut Creek or polluted city driving means you'll need to change your filter more often. Our trained professionals at Gilmore's Auto Service can check your filter for you. In fact, it's often a routine part of an oil change.

When you think about it, a clogged air filter won't allow as much air through as a clean filter. Your vehicle needs this air to efficiently burn its fuel, giving you better fuel economy and performance.

Dirtier filters don't work as well as clean ones. A filter can only hold so much; after that, it allows dirt to pass right into your engine. Air filters come in all shapes and sizes. They also come in different grades. There are high performance air filters available for most vehicles. These high performance filters cost a little more, but they increase horsepower and may improve fuel economy to boot.

So it's important for Walnut Creek drivers to make sure and have their air filter checked. If it needs replacing, it doesn't cost very much at Gilmore's Auto Service in Walnut Creek and it should easily pay for itself in better fuel economy before your next oil change.

A New Battery in Walnut Creek

Hello Walnut Creek drivers, let's talk about batteries. Car batteries are just like any rechargeable battery. They will eventually wear out and die. If you are shopping for a new battery in Walnut Creek, here's some auto advice to help you.

There are two measurements to consider when purchasing a new battery: cold cranking amps and reserve capacity. The power required to start a cold engine is measured in cold cranking amps. The number you need is determined by what kind of vehicle you drive and where you live. In general, higher-cylinder engines require more cold cranking amps than lower-cylinder engines. In other words, an eight-cylinder engine needs more cold cranking amps than a six-cylinder one. Also, diesel engines require more cold cranking amps than gasoline engines.

The weather where you live in CA also determines the number of cold cranking amps you need. The colder the vehicle engine, the more power it takes to get it started. Also, cold CA weather reduces the electrical efficiency of the battery, which reduces the amount of energy available in the battery to start the engine. Thus, in freezing temperatures, you need more power to start an engine, but you have less power available to get it started.

Your friendly and knowledgeable service advisor at Gilmore's Auto Service in Walnut Creek can help you choose an appropriate battery for your vehicle and your lifestyle. If you need extra power owing to cold weather or a need for more reserve capacity, you may want to choose a heavy-duty battery. Just make sure it fits into your vehicle. An oversized battery may give you the power you need, but it's a serious safety hazard if the terminals come into contact with other parts of the vehicle.

Keep in mind that preventive maintenance performed at Gilmore's Auto Service and good vehicle care can extend the life of your battery. Judicious use of electric gadgets and good driving habits are wise and can help you get the most out of your battery.

Hitting the Brakes in Walnut Creek

Safety should always be an element of your vehicle care. So even if you don't care about how your vehicle looks, you should practice preventive maintenance to protect yourself — and other Walnut Creek drivers — on the road. And good safety starts with good brakes.

Brakes need a regular inspection. There are  parts that wear out or wear down, and it's best to replace them before you have serious problems.

Of course, if you are having trouble with your brakes, NOW is the time to fix them. If your brake warning light is on, that's a good sign that you need your brakes checked. You can also tell something is wrong with your brakes by the feel of the pedal or unusual sounds while braking. If the brake pedal is low, feels spongy when you press it or is hard to push, that indicates a problem with your brakes. If you hear squealing, grinding or clunking noises when you brake, that can also indicate serious problems. If vibrations accompany braking, then it is to get your brakes checked.

Brakes come in two basic types. With disc brakes, a rotor is attached to the axle of the vehicle. Padded calipers straddle the rotor and close when the brakes are applied. The resulting friction causes the rotor — and the axle — to stop turning. With drum brakes, brake pads (also called shoes) press against the inside of a drum to create friction and stop the drum, and hence the vehicle's wheels, from turning.

When Gilmore's Auto Service services your brake system, your friendly and knowledgeable service advisor checks all of the brake pads for wear. If they are too thin, they need to be replaced. This is an inexpensive repair at Gilmore's Auto Service compared to what procrastination will cost you. If pads wear away completely, then the rotors and drums can be damaged. They will have to be either resurfaced or replaced, and that can be expensive. But if your vehicle brake pads are worn out, then your brakes are compromised and your stopping power is greatly reduced. You could easily wind up in an accident.

Brake pads come in several different grades such as regular, metallic and ceramic. The higher grades are more expensive, but they also work better. CA drivers who want better and smoother braking should consider upgrading. However, Walnut Creek drivers should NEVER use a brake pad that is lower than their vehicle manufacturer's recommendation.

After your brake pads are checked at Gilmore's Auto Service, it's also wise to have your brake fluid checked. This is a critical element in your brake system. When you press your brake pedal, you are compressing the brake fluid, creating pressure that activates the brake pads. If your fluid pressure is low, it will decrease your braking power. The pads just won't be able to press hard enough against the rotor or drum to stop your vehicle. Just as with worn pads, insufficient brake fluid can lead to an accident in Walnut Creek.

Water can build up in your brake fluid, which can cause corrosion in your braking system. Eventually this can cause your brake fluid to leak. So Walnut Creek drivers should also change their brake fluid periodically. Your vehicle owner's manual will have guidelines on how often it should be replaced, or you can ask a service advisor at Gilmore's Auto Service. 

Remember, Walnut Creek folks, safety first. It's auto advice for all Walnut Creek drivers on the road. You're not just protecting others; you're protecting yourself.

Walnut Creek Car Owners Ask: Why Do I Need to Change My Serpentine Belt?

Any Walnut Creek driver who understands preventive maintenance knows that “if it ain't broke, don't fix it” is bad auto advice. Replacing a part before it breaks is much less costly for Walnut Creek residents than repairing the engine damage that comes after a part breaks or fails. A good example of this is the serpentine belt.

The serpentine belt gets its name because of its circuitous path around the engine. The serpentine belt is driven by the engine and powers a number of systems, as follows:

1. The serpentine belt spins the compressor that generates the cool air for the air conditioning system.
2. The serpentine belt powers the alternator. The alternator generates electricity for use in the vehicle's electrical systems and to charge the battery. Without the alternator, the battery wouldn't last more than a few miles.
3. In many Walnut Creek residents' vehicles, the serpentine belt runs the pumps for both the power steering and the power brakes. In other vehicles, the power steering pump may be electric and the power brakes may use a vacuum boost.
4. On many vehicles, the serpentine belt powers the water pump. The water pump keeps coolant circulating through to maintain appropriate operating temperatures. In some CA vehicles, a timing belt runs the water pump.

When a serpentine belt fails, all of these systems fail as well, which can lead to engine impact.

Replacing parts before they break saves money for Walnut Creek residents by preventing more repairs and the frustration of having your vehicle in the shop for an extended period of time. If you're looking for an adage to apply to good car care, you might remember the old story of how “for want of a nail, the kingdom was lost.”
