How can I increse my gas mileage without loseing horsepower?

I have an 85 Toyota Supra with an inline six non-carberated (fuel injected). I have a K%26amp;N cold air intake. I keep my tires inflated to proper levels. And I only use full synthic oil that I change every 2000 miles. My gas mileage is still less than 20 mpg. Besides changing my driving habbits, what could I try?How can I increse my gas mileage without loseing horsepower?
The easiest ways to increases hp and gas mileage is to;



1.) Add a half-pint accetone (fingernail polish remover) to every three to five gallons of gasoline for 300 to 500 miles. Or have injectors professionally cleaned.

BE ADVISED accetone is corrosive to rubber parts and can result in fuel system failure. (i've never had a problem)



2.) Remove and clean back side of throttle plate, this goo significantly screws up the air flow at part throttle and destroys gas mileage and low speed response. Don't scratch it up or it will get dirty faster(carb. cleaner and toothbrush works). Replace gasket.



3.) Set idle/timing to factory spec. when FULLY warmed-up and be sure to run the factory recommended temp. thermostat only.





Do the above and you will notice a significant improvement in low-speed power and gas mileage!



Consider also running NGK V groove spark plugs and BP gasoline, a new O2 sensor might be in order also.
get a K%26amp;N Cold Air Intake!!! its increases ur mileage %26amp; horsepower!!!

why are you changing synthetic oil every 2000 miles??? fossil oil needs changed less often than that....

Buy Outlaw Octane Booster and try high octane gas just for on tank( unless you use it already)How can I increse my gas mileage without loseing horsepower?
I have found that when I fill up at the pump, the stop will come on on the pump. Waite a while and fill it up some more. You can probably get $5.00 more in it. I had a celica that I did that to and was getting at least 50 more miles on.
not much. there was an article in popular mechanics a few months ago about increasing mpg. they tested different types of gadgets and gizmos that you add to you car, and none of them increased gas mileage at all. some actually DECREASED mpgs. the only thing you can do is drive easier. sorry that is not what you want to hear, but it is the truth. I guess you could look into changing the gearing in the rearend, but that would be major money for any car, especially a 1985 model. save up and buy a Jetta diesel.
Help w/mileage? Car recently tuned up? Check tire pressure. Climb steep hills slowly in low gears.Drive w/o quick stops %26amp; starts.
take out what u dont need
in all honesty, you're wasting a little money on other things which you can just as well be spending on gas....the fully synthetic oil, good as it is, is considerably more expensive per oil change, and you'll have just as good of luck on a good name brand oil, at less than half the cost. A change of the other fluids helps from time to time-such as your transmission fluid and filter(automatic) and changing the oil to synthetic in your gear-box is a good idea, however...the improved viscosity there will help(but will be barely noticed). Keep your air filter clean, run some injector cleaner through on occasion, don't sit and idle your vehicle for very long if you don't have to(like to run the a/c or heaters to warm or cool your car before you drive), don't run the a/c or defrosters(since that also runs the a/c compressor) more than necessary, keep your battery charged up(a low battery will make your alternator work harder, which in turn makes the engine work harder, stealing horsepower, and sucking down gas) make sure your belt(s) are in good shape. Check and keep your power steering fluid up to par(if you have it)..Low fluid in your power steering pump will have the same effect as when you have a dead battery, it will make your power steering pump work harder, again, consuming more gas. Change your fuel filter on a regular basis. Buying higher octane gas won't make a pile of difference, I'd check my owners manual to see what the manufaturer recommends on octane before putting in more expensive gas-the whole idea is to save money, and if you get an extra mile or two per gallon on higher octane gas, but it costs you more, you're not really accomplishing much.
check tire pressure, dont carry heavy things in your car if you dont need to.
all good advice but also running synthetic lubricating oils engine trans rear is proven to reduce friction therefore results in increased mpg. Have heard slick 50 will help but don't have first hand experience.
Installed a vacuum gauge and stay around the economy zone.The gauge will tell you .the best way to handle the gas pedal.Your so call driving habits!!!
use the 89 octane or get a chip
Use brands that improve gas mileage and fuel injectile cleaners in the gas tank. Fuel injectile cleaners clean the valves,and carbuerator.by removing the sludge and buildup, increasing the jet flow for better performance.
