Weight is the enemy of fuel economy. Everyone from here to Mount Holly knows this makes sense.

Some of us in the Mount Holly area carry a bunch of unnecessary weight, and I’m not talkin’ what you see in the mirror.

Guys; sports equipment and tools. Ladies; well, just take a look around the passenger compartment and trunk. I think my car has about forty-five pounds of French fries on the floor.

All that extra weight wastes gas as you drive between here and Mount Holly, and everywhere else.

Lose the junk and save some money.

…And you really only need one of those spare tires.

This fuel saving tip is so simple, no one from here to Belmont will believe it. It has to do with your gas cap.

The first thing is to make sure it’s screwed on tight. If it’s loose, gas vapor will be constantly leaking out; wasted gas.

And air will get in and that can cause your oxygen sensor to read incorrectly and the oxygen sensor will tell the engine management computer to adjust the fuel-air mix and, well, you get the picture; you’ll be burning more gas around Belmont than you need to.

This could cause the check engine light to come on as well.

A worn gas cap can have the same effect. If you constantly smell gas when you walk by your tank, you might need a new gas cap.

So, twist your cap until it clicks three times – that means it’s on tight. Have your Belmont area service advisor at City Chevrolet inspect the cap to see if it needs to be replaced.

See, I told you it was simple.

A lot of gas is wasted in the Belmont area by dirty fuel delivery systems.

Let’s start at the tank. The gas tank gathers dirt, rust and sediment over the years. That’s why there’s a fuel filter to clean the fuel after it leaves the tank. A dirty filter will rob the engine of the clean gas it needs to run efficiently.

The fuel intake components get coated with gum and varnish over time. This results in fuel being delivered inefficiently and some of that gunk getting into the engine. A fuel system service at City Chevrolet will leave your intake as clean as a whistle.

The big fuel thief is dirty fuel injectors. They deliver fuel to the engine at a specified pressure and in a particular spray pattern. When they’re clogged, the fuel doesn’t get atomized the way it’s supposed to and doesn’t get burned as efficiently.

See your owner’s manual or ask your Belmont service advisor at City Chevrolet when a fuel system cleaning is recommended.

No matter how well they’re made, cars in Charlotte NC will have design or manufacturing problems.

And when the government thinks a problem is really serious for people in Charlotte NC, they require the manufacturer to issue a recall notice and fix the car free of charge. The manufacturer then tries to contact everyone in Charlotte NC who owns that type of car to get the recall work done.

These recalls always affect safety, so take them seriously. It’s easy to see if a vehicle’s being recalled.

The government has links on its websites, or just visit AutoNetTV for links.

There are many websites with free recall information and searches. There’s CarFax, AutoByTel and the DMV.

Recalls are serious, but not all that common. But sometimes there are less significant issues, and for these, manufacturers issue a Technical Service Bulletin, or TSB, that tells service centers like City Chevrolet how to repair a frequent or difficult problem.

The pros get updated information through subscription plans, also available in consumer versions for a reasonable cost.

So when vehicle recalls occur, get the work done, and keep you and yours safe.

A question for our Charlotte NC motorists: How long have you been enjoying the romantic glow of your check engine light?

Hey, it’s not there to create ambiance; it’s a warning that something’s wrong. When your check engine light comes on get it checked at a capable Charlotte NC service station.

Many conditions that cause the check engine light to come on affect fuel economy. Some very dramatically.

Always make sure you tighten your gas cap until it clicks. A loose gas cap can cause a false sensor reading that’ll make the check engine light come on.

If your date’s eyes are smoldering in the reflected glow of the check engine light, try to think of all the gas money you’ll save by getting it fixed. Give us a call when you are ready: (866) 409-3468

Let’s talk about alternative fuel vehicles. In their quest to reduce the use of fossil fuels and harmful exhaust emissions to our Charlotte environment, automakers will have a number of alternatives for us very soon.

For instance, Flex Fuel vehicles are already available in the Charlotte area. Flex Fuel vehicles can run on gasoline or on E85 fuel. E85 is a mixture of 85 percent ethanol and 15 percent gasoline. The ethanol is made from corn.

The benefits are in using less petroleum and reduced pollution. The drawbacks are that E85 gets lower fuel economy and that when gas prices are low, E85 can be more expensive than straight gasoline.

You should only use E85 if you have a Flex Fuel compatible engine. Flex Fuel vehicles have special seals and gaskets that can stand up to the high alcohol content of E85. Using E85 in a regular engine can lead to gas leaks and fires.

Diesel engines have been around the Charlotte area for a long, long time. Modern diesels are very refined and fuel efficient. Diesel fuel can be made from renewable sources like vegetable oil, too. Diesel fuel from algae and sunlight is reported to be pretty close to being commercially viable.

There are also a number of natural gas vehicles on our Charlotte roads. Gasoline engines are adapted to run on compressed natural gas. It’s less expensive than gasoline and burns very cleanly. You can even refill it with a special pump from your gas line at home.

Natural gas engines don’t make as much power and don’t get as good of mileage, but they cost less per mile to run. The big inconvenience is that the tank that holds the compressed natural gas takes up a lot of room; even your whole trunk! And there may not be places to refuel on a road trip from Charlotte.

Plug-in electric vehicles are now available in our Charlotte area. Battery technology is the limiting factor right now. Electric cars have a limited range and are really best for use close to home. As battery technology advances, electric cars will perform closer and closer to conventional power plants.

That brings us to hybrids. There are a bunch of hybrids on our Charlotte roads, with more to come. Hybrid technology combines internal combustion engines with electric motors.

A mild hybrid has a regular gas or diesel engine that’s assisted by the electric motor. The electric motor can propel the vehicle by itself up to a certain speed under gentle acceleration. There are mild hybrids in full-sized pickups and SUVs. They deliver city fuel economy similar to their highway ratings.

A full hybrid will rely primarily on the electric motor for power. It’ll have a small gas or diesel engine that generates electricity for the batteries.

Another breakthrough technology is hydrogen fuel cells. Fuel cell vehicles use hydrogen to generate electricity. Several global car makers have prototypes on the road. The appeal is that the only thing that comes out of the tail pipe is water vapor. It’ll take some time to build a national infrastructure of hydrogen fueling stations before there’s widespread use.

A quick word about safety around hybrid and electric vehicles. Unlike the battery in your current family car, these carry enough voltage to kill you. Never mess around under the hood or with the batteries or electrical wiring. Your Charlotte service technician at City Chevrolet is trained to safely disable the flow of electricity before performing maintenance or repairs on the vehicle.

Hybrids are really not do-it-yourself vehicles unless you’re specifically trained on hybrid systems.

For those of you in Charlotte NC who pay attention to these things, you may have been hearing about the new direct injection engines and want to learn more about them. Some deliver the power of a V8 with the economy of a V6.

For example, in one family of engines the conventional V6 makes about 250 horsepower. The direct injection version of the same engine makes over 300 horsepower and gets essentially the same gas mileage. The turbocharged version makes over 350 horsepower.

So what are the differences from a conventional engine?

The core difference is in the fuel injection system. The system most vehicles use now is called a port injection system. The fuel injector squirts fuel into a port just outside the cylinder where it’s then drawn into the engine with the air.

With a direct injection system, the injector squirts the fuel directly into the cylinder. The gain in power and economy come because fuel injected directly into the cylinder during the combustion cycle is burned much more efficiently.

First, the fuel is squirted in at hundreds of times more pressure, so it’s atomized much better and burns cleaner and stronger. The other big advance is in electronics. Faster engine management computers can control the additional precision required to manage direct fuel injection.

Fuel injectors are precision instruments. They have to deliver a precise amount of fuel at exactly the right time. The design of the engine also dictates a particular spray pattern for the fuel. If a fuel injector is dirty or gummed up, it can’t do its job as well. That means less power and worse fuel economy for your SUV and can lead to damaged fuel injectors.

Replacing fuel injectors isn’t cheap. Direct injection injectors are even more expensive because of the extremely high-pressure they use. Same thing for diesel fuel injectors; we’re talking mortgage payment-range to replace a set of diesel injectors.

A professional fuel system cleaning from City Chevrolet gets out the gum and varnish in the whole system, including the fuel injectors. Keep those injectors clean and they’ll last a long, long time.

The function of the fuel filter is pretty self-explanatory. It filters your fuel. The fuel filter is in the fuel line somewhere in between the fuel tank and the engine. Both gas and diesel vehicles around Charlotte NC use fuel filters.

For more information about your fuel filter, visit City Chevrolet or come by our shop located at 5101 East Independence Blvd in Charlotte, NC 28212.

Generally speaking there’s not a lot of dirt in our Charlotte NC auto fuel supply, but there is enough that you want to screen it out. The problem actually gets worse the older your vehicle becomes. That’s because dirt, rust and other contaminants will settle out of the fuel and onto the bottom of the fuel tank. After your SUV is five years or older, it can actually have a fair amount of sediment built up.

That just means that the fuel filter has to work harder as your SUV ages. It’ll get clogged sooner and need to be replaced more often.

A symptom of a clogged fuel filter is that the engine sputters at highway speeds or under hard acceleration. That’s because enough fuel is getting through around town, but when you need more fuel for speed, enough just can’t get through the filter. Obviously, that could be dangerous if your car or truck can’t get enough power to get you out of harm’s way.

For just that reason, fuel filters have a bypass valve. When the filter is severely clogged, some fuel can bypass the filter all together. Of course that means that dirty, unfiltered fuel is getting through to be burned in the engine.

This dirt can then clog and damage your fuel injectors. Now injectors are not cheap to replace, so you don’t want to cause them damage just because you didn’t spend a few bucks to replace a fuel filter.

You know, in a way, the fuel filter can be the poster child for preventive maintenance. It’s a little part, it’s simple and it’s cheap to take care of. But if it’s neglected, it could lead to thousands of dollars of repair bills.

Those auto service schedules in your owner’s manual are there for a reason. If ever you don’t understand a recommended service, just ask your Charlotte service advisor at City Chevrolet. We’ll be happy to explain.

Today we’re talking about fuel system cleaning. The first thing to know is how important it is to have a clean fuel system. You need fuel to go, and the cleaner your fuel system, the more efficiently the fuel will burn. That means more power and better fuel economy.

A clean fuel system saves money at the pump. We guess you could say, it all starts and ends at the pump. One of the most important things you can do to keep your fuel system clean is to buy good quality gas. Major brands have detergents that keep gum and varnish from rapidly building up in the fuel system.

So buying cheaper gas can actually cost you in the long run. Now, most cars on the road are more than five or six years old. That means they’ve had time for some dirt and rust to start accumulating in the fuel tank. This junk needs to be filtered out of the fuel before it hits your engine. That’s the fuel filter’s job.

When the fuel filter is clogged, the dirty fuel will bypass the filter and go on up to the engine where it can clog fuel injectors and get into the cylinders. That could do some damage. So you should have your fuel filter changed when recommended. Check your owner’s manual or ask your service advisor if your fuel filter is due for replacement.

The fuel then goes up into the throttle body. This is another area where varnish and gum can accumulate. A professional fuel system cleaning will use a combination of special cleaning chemicals and old fashioned swabbing to clean out the throttle body. Now, the fuel injectors are the last stop in the fuel delivery system.

It’s real important to keep those fuel injectors clean. The fuel injectors need to deliver a precise amount of fuel, at exactly the right time, in a particular spray pattern. They just can’t do that if they’re dirty. Dirty fuel injectors really rob power and waste fuel.

It is important for the fuel system proper, but there are a couple other things that will help keep your engine clean as well. Of course, air is mixed with the fuel before it’s burned. Dirty air means dirt gets into your engine, so you need to replace your engine air filter when it’s dirty.

The PCV value routes unburned fuel that escapes into the lower engine back up into the intake system to be burned. A sticky PCV valve needs to be replaced to make sure that system is working properly and the breather filter needs to be replaced if it’s dirty as well.

Do all these things and your engine’s air and fuel will be as clean as possible. You’ll get much better fuel economy and better power

No one in Charlotte NC likes high fuel prices. But if one good thing has come about, it’s that people are really focused on how to reduce their fuel consumption. North Americans literally drive billions of miles less each month during times of high fuel prices. But we still need to drive, so it makes sense to try and increase our fuel economy however we can.

Let’s look at a real life example of one of our AutoNetTV producers. He has one of those really big SUVs. Lots of kids and horses to haul around, you know. His family was planning a four day camping trip. Here’s what he did to cut his fuel costs:

First, he installed a new, high flow engine air filter. Then he had his service center change his oil, flush his cooling system and service his front and rear differentials along with the transfer case. He also had a fuel system cleaning, replaced his PCV value and breather element. He also made sure his tires were up to the recommended pressure.

Now this cost several hundred dollars. But keep in mind, it all needed to be done anyway – it was all scheduled, and some of the work was overdue.

So he headed out, loaded with nine people and pulling a ton of trailer with everything needed for four days of camping. When the trip was over, he had turned in the best fuel economy he had ever gotten on that vehicle. It had improved 25 percent. He saved $48.00 on that trip alone. And the savings keep on coming every day.

Here’s a quick summary of what you can do to save fuel in Charlotte NC. First get caught up on your routine maintenance. Nearly every scheduled service item can save you some fuel. If its time for a tune-up, git’er done. That’s a big item.

If your check engine light is on, have your Charlotte NC service center at City Chevrolet figure out why and fix it. Check engine problems can be real gas wasters.

Proper tire pressure and wheel alignment can really help as well. Try not to carry around a bunch of stuff. An extra hundred pounds can cost a mile per gallon.

Now you may not want to hear this, but the single biggest fuel waster for most people is their right foot. Zooming away from stop lights and hot rod lane changes really waste fuel. Take it easy, don’t speed and plan ahead.

Finally, you may have noticed that we haven’t mentioned any magic pills or devices that will double your mileage. That’s because there aren’t any. Some may help a bit, but there are a lot are scams.

Do some research and check with your service advisor at City Chevrolet before spending your hard earned cash.
