How can I get better gas mileage in my Chevy Impala?

I switched to a K&N air filter. It's a 2000 with about 80,000 miles. With such high gas prices, I want to get the most per gallon.

Some ideas... Here are some ideas... a. Keep the air filter clean. B.

Keep the car in tune... change spark plugs... new cap and rotor... new wires. C. Drive softly... easy take offs... gradually building speed and keep speed low... use brakes very little (brakes convert gasoline energy to heat and exaust that enegy to the enviroment--wasteful).D.

Avoid 10% Ethanol fuel mixes... Alcohol burns with less oxygen... it burns much richer... 14.7:1 (fuel to air weight) for gasoline... about 19:1 for alcohol... so you lose fuel economy (about 5% less than pure gasoline). Also unless you car is specifically designed for alchohol use (Flex fuel) you car will suffer some corrosion to fuel filters, aluminum fuel lines, injectors, etc that will become apparent someday.E. You improved the efficiency of you air intake... you can improve the efficiency of your exhaust too... tuned headers and a low flow resistance exhaust system will improve your fuel economy further.

F. The Fitch Device... the only device has a number of benefits including the ability to burn a lower octane (cheaper fuel) without pre-ignition problems. Look into that... do a search on Google for "Fitch Device".

I think the only device on the market that has some measureable benefit.G. Keep track of your fuel economy in a log or spreadsheet. Sources: Ideas .

Here are some tips I go by Don't speed the faster you go the more fuel you use and you will use a lot more there is a big difference so if you can take it 5-10 mph slower you should do that :). Always make sure your tires are properly inflated. Do not warm up your car before you get in it.

On the highway use cruise control since it helps you keep a steady speed you get a little better gas mileage. The last thing I can think of is making the car lighter. Hope that helps!

Some tips to get better gas mileage... 1) Slow down. Do not accellerate quickly. Do not speed.

If you see a red light or stop .

This is for all cars TIP #1: Only buy or fill up your car or truck in the early morning when the ground temperature is still cold. Remember that all service stations have their storage tanks buried below ground. The colder the ground the more dense the gasoline, when it gets warmer gasoline expands, so buying in the afternoon or in the evening... your gallon is not exactly a gallon.In the petroleum business, the specific gravity and the temperature of the gasoline, diesel and jet fuel, ethanol and other petroleum products pays an important role.

A 1-degree rise in temperature is a big deal for this business. But the service stations do not have temperature compensation at the pumps. TIP #2: When your're filling up do not squeeze the trigger of the nozzle to a fast mode.

If you look you will see that the trigger has three stages: low, middle, and high. In slow mode you should be pumping on low speed, thereby minimizing the vapors that are created while you are pumping. All hoses at the pump have a vapor return.

If you are pumping on the fast rate, some of the liquid that goes to your tank becomes vapor. Those vapors are being sucked up and back into the underground storage tank so you're getting less worth for your money. TIP#3: one of the most important tips is to fill up when your gas tank is HALF FULL or HALF EMPTY.

The reason for this is, the more gas you have in your tank the less air occupying its empty space. Gasoline evaporates faster than you can imagine. Gasoline storage tanks have an internal floating roof.

This roof serves as zero clearance between the gas and the atmosphere, so it minimizes the evaporation. Unlike service stations, every truck is temperature compensated so that every gallon is actually the ex act amount. TIP#4: VERY IMPORTANT: Another reminder.

If there is a gasoline truck pumping into the storage tanks when you stop to buy gas, DO NOT fill up-- most likely the gasoline is being stirred up as the gas is being delivered, and you might pick up some of the dirt that normally settles on the bottom. Hope this will help you get the most value for your money Sources: email that was sent to me it works .

1 ChicagoTRS, regarding your answer "Some tips to get better gas mileage...": You bring me another idea... change out your motor oil, transmission fluid, rear-end gear oil, etc with synthetics... they create a lot less friction and can boost rear-wheel-horse power by a measureable amount (10 +HP on a 300 HP engine) and fuel economy as well. Mobile 1 is great to use...

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
