Does Running Your Car’s Air Conditioner Really Affect Gas Mileage

January 17th, 2012 admin Comments off

When it gets warm outside, your air conditioner becomes your best friend. This is most definitely true in your car, where temperatures can sky rocket to 170 degrees under direct sunlight. But most people these days are under the impression that the more you run your air conditioner the more gas your car will guzzle. Now that gas prices are higher than the cost to eat at McDonald’s, people are starting to take precautions and do what they can to help with their cars fuel economy. The assumption that running your air conditioner burns way more gas is somewhat untrue. Leaving your air conditioner off makes barely any difference in the amount of gas you burn. With the advent of modern, more fuel efficient cars, this myth is busted!

The air conditioner draws its power from the engine which uses some gas, but with today’s cars, this use of gas is minute. The air conditioner can decrease the fuel economy of your car up to 20% in some vehicles, but it depends on the type. Driving with the air conditioner is more fuel efficient than driving with the windows down. Driving with the windows down creates drag which means that your engine has to work harder to keep your car at the current speed; this burns more gas than if you just ran your air conditioner.

In the long run, using your air conditioner is far better than any other means of cooling yourself off in the car, unless you’re driving in traffic. When you drive in traffic you aren’t going very fast so the drag on the car is minimal. In these cases, you burn more fuel running the air conditioner than having the windows down. That makes sense. When you drive on the highway you can use either the air conditioner or the “window down” method to cool yourself, because, honestly, there is no noticeable difference in gas usage at those speeds.

Here are some tips about you and the heat in your car. Before you get into a hot car, roll down the windows and let it air out. There is nothing worse than getting into a hot car, sitting on a lava hot seat, touching a super hot steering wheel, and breathing stuffy super heated air. Your car needs some time to cool down for itself and for you. Once you believe it is cool enough to actually sit on the seat, turn on the car and run the air conditioner on recirculation. This will help the car cool down much quicker, and you can be on the road fast without sacrificing a layer of your precious skin.

So now that you know the air conditioner can be your fuel efficient friend, maybe you won’t be so quick to turn it off or ignore it in favor off putting the windows down and choking on bugs. The air conditioner in your car burns much less gas than your window method, so give your air conditioner a chance and be cool in the heat.

Tools And Tips To Help You Save Money At The Gas Pump

January 17th, 2012 admin Comments off

Doesn’t it aggravate you everytime you have to buy gas? For most Americans, there is a way to save money in the long run at the gas pump. Outlined are some very good ways to save money at the pump.

1. Keep your vehicle maintained

Surprisingly enough, statistically the nation as a whole does not do proper preventative maintenance on their cars. Did you know that if your oil is dirty, you are getting less fuel economy? If you don’t want to change your oil so often, there are many new oils out now that last for five, ten, even twelve thousand miles before you need to change it. It may cost a dollar or two more per quart but in the long run, you save money.

Also, most Americans don’t tune their automobiles up as scheduled. I conducted a private study for one of the companies that I used to work and contacted over 1000 auto dealerships and independent auto shops throughout the United States and Canada. I spoke to the service managers in all of these shops and the answers were the same everywhere I called.

Most people simply refused to have their auto’s tuned up on schedule. The customer would have the auto repair that they were there for and simply nothing else done.

Did you know that a cold firing plug can reduce your fuel economy up to 8 gallons per mile? The manufacturer of your automobile placed a schedule of when the auto should have the plugs changed. For most vehicles, it ranges from 12,000 to 30,000 miles. You should have the plugs and wires changed on schedule. If you would like to get plugs that last longer, consider a good set of platinum plugs. You can get Bosch platinum+2 for only a dollar or two more per plug and platinum+4 for a few dollars more per plug.

Change your timing belt on schedule.

It is most important that you change your timing belt as scheduled. There are a couple of reasons for this. Number one, as the belt wears out, your fuel economy gets worse. The second reason is because if your car is a V6 or V8 with duel overhead cams (DOHC stamped on engine), if it breaks, you are going to have very costly repairs in the long run. 9 out of 10 engines that the timing belt breaks in with DOHC bends valves. This causes you to have to rebuild the heads or replace the heads at a very high price.

Change your air filter on schedule.

This is again crucial to the fuel efficiency of your automobile. Just like us, your engine has to breathe. Without a clean air filter, you will burn a lot more fuel because you don’t have the proper air/fuel mixture. It is usually recommended to change them every time you change your oil, however, you may consider purchasing a K&N filter or one from one of their competitors that doesn’t have to be changed but merely cleaned. This will save you a lot of money over the lifetime of your car, plus if it needs to be cleaned, you merely blow it out with compressed air.

Make sure you have your PCV valve changed on schedule.

For even some of the best people who take care of their cars, this is a critical step that is often overlooked. The PCV valve doesn’t cost but a dollar or two and usually last as long as your plugs do.

Do an upper-end cleaning on your engine.

This is where you have your intake and valves cleaned. A few years ago, the intake and valve covers had to come off the vehicle to do this. Now, you can buy the chemical at the auto parts store yourself and clean the intake in about 15 minutes. The chemicals have the directions for how to do it, but believe me anybody can do it, and you don’t have to spend up to $600 for a shop to do it for you. It will instead cost you about $8.

Make sure that your tires are in good shape and aired at your vehicle manufacturer’s recommended pressure.

The tire may say that you can inflate to 50 p.s.i., however, that is maximum pressure for the tire. If you look inside the driver’s door at the inspection tag from the factory, you will find the manufacturer’s recommended tire pressure. It is recommended because they have performed many tests to find where the car performs best at and found that the best performance comes from this setting.

Have your transmission flushed about every 30,000 miles.

This keeps the vehicle shifting properly and also allows you to get better fuel efficiency. A standard flush doesn’t cost very much and can make your transmission last up to three times as long as it normally would.

Last of all, make sure that you change your belt as scheduled.

As the belt gets older and wears, a certain amount of slippage occurs, ultimately making you have to run the engine harder. It is also a good idea to keep it changed on schedule because of the unfortunate event that it breaks, you lose your power steering, a/c, and alternator.

2. Consider doing a few modifications to your automobile.

There are a few mods that you can do to you auto that will save quite a few dollars at the pump.

The first thing that you can do is replace your muffler with a performance muffler. Yes, they are louder but they also let a lot more exhaust flow through. This ultimately means you pick up horsepower and also fuel efficiency.

Case study: 1995 Chevrolet K-1500. Replaced factory exhaust with Dynomax dual outlet muffler and actually picked up 28 horsepower on the dyno and almost 2.3 miles to the gallon of fuel.

The second modification that you can do is change your air intake system and put a cold-air intake on it. This is going to cost anywhere from $200-$500 for the do-it-yourselfers and $400-$1000 to have it done at a shop. It does increase horsepower and fuel efficiency, but in the long run, isn’t really worth the money unless you just want it.

The last modification that you could do is put a hydrogen fuel cell on your car. You can actually Google this, there was a case study performed and the video is on YouTube of a guy with a Saturn. He was getting 37 miles to the gallon at baseline. He installed the cell on his car and actually got over 62 miles to the gallon. That is an incredible increase in fuel efficiency.
