GM cold air intake, less of a lead foot. headers, complete exhaust. run top tier fuel, 87 octane if its not a 6.0 or 6.2. Remove any unnecessary weight. get an HID kit and Quit whining because 15 is good for a fullsize chevrolet vehicle.:crazy:

Im forced to disagree with you on the tornado. This is one of those things where people think they know better than GM engineers. if this actually worked, GM would have don that instead of design the MAF sensor with those little squares in them. I also dont think that throttle body spacer will do shit on the nnbs.

I hate to bring this up, because I'm not really with the grammer police. But this is a particular pet peeve of mine....

it's referred to as "MPG", instead of "MPG's". The "'s" is built into the "M".


And back on topic....driver mod is best/easiest way to increase your MPG. Google "hypermiling" for tips/tricks.

Helium in the tires, Pressurizing your cab while driving also helps, just buy a little compressor and hook it up to the HVAC unit and have it pump air through the vents. If you have a tonneau cover or a rape dome fill it with helium filled balloons or if you can achieve a tight seal just fill 'er up with helium without balloons. Drive with only 2 gallons of gas in the tank, less weight means more MPG""""''''"""s. Run only 2 quarts of oil in your engine, cuts down on the weight and it is better for the environment. Replace transmission fluid with olive oil. It is less dense than ATF and actually lubricates better. Extra virgin only.

Basic driving habits can also do wonders for your economy. Try throwing a book under the gas pedal so you can't achieve more than 1/4 throttle. Follow highway tractors extremely close, within three feet of the trailer to achieve a slipstream and windbreak effect. Drive ONLY with the wind, never against it. If you are driving into the wind adjust course accordingly. Remove your air intake and filter. They provide unnecessary restriction to the throttle body. Remember, The easier it goes in the more power you are making.

Thin out your gasoline with 1 cup of olive oil per gallon of gas for a beneficial lubricating effect and savings at the pump. If everything stays well lubed the engine will run better. Also try using four wheel drive all of the time. If all four tires are powered the engine has to work less, also you will save brake pads this way.

It's not unreasonable to want to avoid burning off your money any more than necessary. No matter what you drive it's not unreasonable to want to improve.

People who say "if you want fuel economy drive a Civic" who drive lowered trucks: If you want low, drive a car! Those who say it and drive lifted trucks: If you want off-road ability, drive a tank!

There are few cost-effective modifications that can be done to increase your fuel economy. Most cost more than they'll ever pay back.

Most of what you CAN do is driving style. As mentioned above, read up on hypermiling; you don't have to do the extreme stuff or drive really slow, but learning about it will help. You could experiment with increased tire pressure; with stock-sized tires you should never go less than GM's recommendation, and with any tire you should never exceed the maximum pressure stamped on the sidewall.
