"Hi, I'm Dave Erb, from Dave's Ultimate Automotive, and we'll be talking about how to get good gas mileage, or how to get better gas mileage. Well, it depends on what you consider good gas mileage. Some of us don't drive vehicles that get good gas mileage, but you want to get the most out of the vehicle you drive. First of all, it starts with maintenance, keeping your car maintained properly. Keeping proper air pressure in your tires is a biggie. If your tires get low, that makes your car work harder, and that will cost you more gas mileage. Then, there's the whole AC on, AC off, conundrum. Studies say that if you keep your AC off, below forty miles an hour, and run it with the windows down, and as you get above forty miles an hour, that wind drag starts to come across the vehicle, and you turn your AC on. That's the most efficient way concerning AC, to save yourself gas. Keeping once again, the car maintained properly, as far as fluids flushed, and changed every thirty thousand miles. Keeping the fuel injection service, fuel injection service done. Keep all that carbon buildup out of the intake system, and your injectors running clean, will help you save mileage. Some people even say, that keeping your car clean and waxed, keeps wind resistance down, and that saves you gas mileage, so all these things combined. Keeping your air filter cleaned, and keeping things in tune, and keeping things in good shape, to keep you from dragging your car down, or creating more work for your car. Those are the things that are going to get you the most gas mileage, with your vehicle. That's it."
