how to acheive better gas mileage

[ASTCB7]

what can i put in my car to get better gas mileage?

[Djmoua]

a manual transmission.

water.

or a tune.

[PointBlank]

New air filter and spark plugs.

Oil change wouldn't hurt.

Fuel injector cleaner.

having the right amount of air in your tires helps too.

Having your ride at it's peak oem performance will definitely get you the gas mileage.

1. complete ignition tune up. Plugs, wires, cap, rotor.

2. Fuel filter, and clean non restrictive air filter

3. the correct oil and a new filter

If you have any vacuum leaks, these are fuel eaters! Fix them! such as, broken vacuum lines, intake manifold gasket, a worn/old or bad map sensor!

Definitely keep your coolant temps sensors in prime condition! IF they dont see operating temp they wont go into adaptive or closed loop.

Low coolant needs to be topped off!

Keep your valves adjusted right! Make sure your timing belt is in time! a stretching old belt will also start to eat at gas mileage.

Good tires, tire pressure, and good tire alignment is very crucial to mpg.


These are just the quick ones i can think of...

Definitely need to add...

good switching o2 sensors,

non restricting exhaust, a failed cat or partially plugged catalytic converter will cause the engine to work harder to expel the exhaust.

Weak coils will also lower mpg. if you see any carbon tracking inside the dizzy when you change the cap and rotor. you might want to look into a new coil.


also, use the recommend fuel grade. Some people believe that if 87 works good, then 92 will really wake it up. Not so. higher octane ratings slow the burn time down to prevent predetonation. if your car recommends using 87 use, that's the fuel grade the honda engineers found to get the best performance and mpg. Older cars will sometimes be picky and need to have a higher octane gas due to the raised, though minimally, compression due to carbon build up on the pistons. you'll have to play around with a tank or two to see if switching gas grades will fix a slight miss, or make it worse.

02 sensor is one if the most commin things that kills gas milage, get that replace and yall shall see gas improvements

thanks for the feedback

Your own driving habits play a HUGE part in it as well. A heavy foot can cost you 5mpg or more. Drive between 2k and 3k RPM. I always shift at 3 when I'm being conservative.

Also, if you have a lot of heavy shit in your car... get rid of it. I'm a musician, and I would often carry my equipment around in my back seat. 150-200lbs, usually. That extra weight made a noticeable difference in my gas mileage.

Follow a Hummer H2, those things are like bricks...let them take up all the aero drag lol

or option 2:
-get a lip (helps divert air away from chassis underside)
-skinnier tires (less aero drag)
-lower you car (less aero drag)
-use synthetic oil (less friction in engine and more power too)
-dont use A/C when you can
-close all windows when going over 45-50mph

Or just draft a semi...

I tried it in the Fit. I couldn't get it to pull me along enough. Either the Fit is too aerodynamic, or I wasn't close enough.

air pump ... more air in more exhaust out .. i look at it that way... also stock tires not wide ones ..less friction

Mythbusters confirmed (I believe). You just have to be really, really close. Which is dangerously stupid I might add.
