Hey Walnut Creek Drivers: How Do You Save Gas?

Higher Walnut Creek fuel prices aren't going away any time soon. That's not good news for our wallets. A lot of Walnut Creek drivers are trying to find ways to cut down on fuel consumption and hang on to some of their hard-earned money.

North Americans drive billions of miles less during months of high fuel prices. That's right, billions. Of course CA vehicle owners can't stop driving altogether, so we still need to find other ways to cut fuel bills.

Preventive maintenance at Gilmore's Auto Service in Walnut Creek and good vehicle care can actually pay for themselves by lowering our fuel consumption. Here's a real-life example of how that can work.

A family planned a four-day camping trip. Before leaving, they took their SUV into Gilmore's Auto Service for an oil change. They flushed the cooling system, serviced all three differentials and cleaned the fuel system. They replaced the PCV valve and breather element. Then they checked the tires to ensure they had enough air.

This was several hundred dollars in maintenance and repair. You may be thinking how the family could possibly recoup the cost in gas and save money. First of all, the repairs all needed to be done anyway. Even if the costs aren't recouped, many of them will pay for themselves by preventing even more costly repairs later. Also, the family had planned and budgeted for the routine maintenance, so it didn't cut into their trip allowance.

The SUV pulled a one-ton trailer and hauled everything the family needed on their camping trip. At the end of the trip, the owner was surprised to learn the SUV had actually gotten better gas mileage than it ever had before—even with that heavy load. The repairs and maintenance at Gilmore's Auto Service had improved the gas mileage by 25%! The family saved $48.00 in gas on their four-day trip. And they are continuing to reap rewards from the improved mileage.

So what can you do to save fuel? First, stay caught up on routine maintenance at Gilmore's Auto Service. Almost every maintenance item listed in your owner's manual will maintain or improve your fuel economy. Second, take your vehicle into Gilmore's Auto Service for scheduled tune-ups. And third, take care of needed repairs. You may be surprised at how much you save at the pump and probably with the improved vehicle performance as well.

If your Check Engine light is on, find out why and take care of it. Some of the problems that set off that warning light can seriously reduce fuel efficiency.

As you schedule preventive maintenance, don't forget your tires. Proper tire pressure and wheel alignment are both essential to good fuel economy.

Here's some more auto advice about some simple things you can do to improve fuel economy, beyond maintenance and repairs:

Dump the junk. More weight in your car equals more fuel. You'd be surprised how much stuff people carry around in their cars. That adds up to a lot of extra fuel. One hundred pounds of extra stuff in your vehicle can add up to the loss of one mile per gallon of fuel.

Get the lead out. No, don't speed up, slow down. Get the lead out of your right foot. The single biggest drain for most Walnut Creek vehicles is speeding or sudden accelerations. Slow down and go easy on turns and lane changes, and don't treat every stoplight and stop sign like a green flag. These small changes can add up to quite a bit of change in your pockets.

We haven't mentioned the pills you can drop in your gas tank or special devices you can hook on your fuel line in order to increase fuel efficiency. There's a simple reason for that: they don't exist. There may be some truth behind some of these claims, but most of them are full-out scams. And if any of these things do actually help, it's not nearly as much as the things we've listed here.

Be smart. Your vehicle and your wallet will thank you for it.

Growing Old Together (Maintaining an Older Vehicle)

More and more of us are hanging on to our vehicles longer.  A company by the name of HIS Markit recently released a report that shows the average age of light vehicles in the U.S. is now 11.8 years.  Light vehicles are cars, SUVs (sport utility vehicles) and CUVs (compact utility vehicles). 

In Canada, the average life expectancy of a vehicle there is around 13 years, and in the U.S., it's around 15.  Vehicles are lasting longer these days, and there are several reasons for that.

One expert cites better technology and overall quality improvements.  While in past years, vehicles were made mainly of heavier steel components, more modern vehicles contain lighter magnesium and aluminum alloys, high-strength steel, polymers and carbon fiber.  They last longer and reduce the overall vehicle weight, and that can contribute to better fuel economy.

Modern internal combustion engine designs have been improved, and since they use more computers, they are more efficient with better performance.  Those factors also contribute to a longer-lasting powertrain.  In fact, it's not unusual to see a powertrain easily last 150,000 miles/250,000 kilometers or more with no major failures.

Drivers are also taking their vehicles in more regularly for periodic maintenance.  Choosing one service facility for all your maintenance can contribute to your vehicle's longevity, too, since technicians know your vehicle's repair and service history.

If you bought your vehicle taking out a 5-year loan and you keep it 11 years, you've managed 6 of those years without a payment, always a nice feeling.  Plus, a bonus is that you get very familiar with every aspect of that vehicle's sounds, smells, handling, stopping characteristics, visibility and limitations.  And the more familiar you are with your vehicle, the more confident you can be as a driver.

Using Proper Fluids in Your vehicle

Today, Gilmore's Auto Service is writing about the proper fluids for your vehicle. It's become more complicated with changes in automotive design and manufacturing. It's not that people in Walnut Creek are confused as much as they don't realize how much things have changed in recent years.

If you have questions about the fluids in your vehicle, please don't hesitate to stop by Gilmore's Auto Service. You can find us on 2151 N Broadway in Walnut Creek, CA 94596.
Just give us a call at (925) 939-9430.

Let's take engine oil. Twenty or 30 years ago, there were just a handful of different weights of oil. The weight of an oil is a scientific measure of its properties, particularly its viscosity or thickness.

It was common in those days to use a lighter weight oil in the winter when it's cold outside. That way the oil would be able to splash around inside the engine and protect the parts before it was fully warmed up. And a heavier weight oil would be used in the summer. The thicker oil wouldn't thin out too much in the summer heat and vaporize in the engine.

Modern valve trains have become very complicated with more moving parts and small passages than ever before. The valve train is in the top of the engine, so when the vehicle has been turned off for a while, the oil tends to run down to lower areas.  That means the valve train parts are vulnerable at start-up, before the oil starts circulating.

So new weights of oil have been introduced to meet the engineering specifications of these newer engines.

Manufacturers are recommending specific weights of oil. The recommendation is often printed on the oil fill cap. It's certainly in the owner's manual. Of course, Gilmore's Auto Service in Walnut Creek can look it up for you.

It's more important than ever to have the correct weight of oil. The wrong weight could actually harm the engine.

Other fluids are also becoming more sophisticated. In the last few years new types of transmission, power brake fluid and coolant have all been introduced for some of the same reasons as for engine oil.

In addition, vehicle manufacturers are now using a wider variety of materials in these systems. Looking at the cooling system as an example, it used to be that the parts were all made out of steel or iron and the hoses were rubber. Now, some parts are plastic, aluminum or other materials.

So the anti-corrosion additives contained in the coolant, or anti-freeze, need to be different in order to protect the different materials used to make the cooling system. If you use the wrong coolant that wasn't formulated to protect your plastic cooling system parts, they could become corroded and fail. And if you're using the wrong coolant, your cooling system won't be covered under warranty. So it's important to use the right coolant and to not mix different types.

Your owner's manual or service advisor at Gilmore's Auto Service can make sure you're using the right type. You may have heard of universal coolant. Universal, or global, coolant can be added to other types without harmful reactions. That's OK for an emergency top off, but following your manufacturer's recommendation for your vehicle or other auto type is always a safe bet.

In the area of brake fluid, there are a couple of new formulations. It's important to remember that the new ones aren't better than the old ones. They're just different formulations for different vehicles. So if your vehicle calls for DOT 3, using DOT 4 or DOT 5 is not an upgrade. Use the recommended formula.

There are fluid formulations for vehicles with higher mileage. These are special engine oil, transmission fluid and so on that contain additives to condition and restore seals and gaskets in older engines.

They're fine to use as long as they're a variant of the proper fluid. In other words you can use a high mileage engine oil as long as it's also the correct weight recommended by the manufacturer. Same goes for transmission fluid; as long as it's the right type for your transmission.

A Hot Mess (AC System-Compresser)

Air conditioning used to be a real luxury in a vehicle, but now it's standard in most.  Your vehicle's air conditioning system is built to last a pretty long time, but like anything mechanical, sometimes it fails. 

It helps to know a little about how the A/C works. There's a compressor that pressurizes the refrigerant (you probably recognize the term Freon).  That makes it hotter, so it then goes through a condenser that cools it off.  Then another component takes out impurities and humidity before the Freon goes to a device that makes it lose pressure before it goes to the evaporator.  That's where it gets colder and takes the humidity out of the air. Then your vehicle's ventilation system blows air over the evaporator, cooling the cabin air that gives you such relief on a hot day.

Of all these parts, one that does a lot of work is the compressor.  It has to compress that refrigerant and circulate it through the system.  It turns on and off several times when it's working. The good news is that if it's going to fail, it sometimes lets you know. 

One of the signs that your air conditioning compressor is going bad is a noise under the hood when the engine is on, sometimes a squealing or grinding sound. It usually is pretty noticeable. Compressors have a bearing that can seize up after time, causing the belt that drives it to squeal when it's trying to turn something that won't turn.  It will sometimes cause that belt to break. 

Your service advisor can tell you if your compressor is repairable or must be replaced.  In the case of a broken belt (often a serpentine belt that drives several components) the belt will have to be replaced as well.

The compressor also has a clutch that turns the compressor on and off so it doesn't have to run all the time. Sometimes that clutch can fail, too, and your service advisor will often recommend you replace the compressor and the clutch at the same time. Our technicians can help make sure your air conditioning system keeps its cool, and you along with it.
