finally changed to 5w20..max mpg

[90Haccord]

Like title says, finally changed to 5w20 from 10w30 as recommended by my mechanic, gas prices are KILLING me, I hope this helps with some MPG. I've been semi "hypermiling", best so far was 30.4mpg with a 10" sub and amps in the trunk(downgraded from a previous heavy ass system). I changed air filter, aired tires up to max rating. This is an automatic, any other suggestions for MPG? Plugs are decently new, but wires might be old? that effect MPG?

The only shitty thing was 5w20 cost 26.99, 10w30 was only 19.99 why the difference?

Plus, Fuel Filter affects MPG and how dirty your fuel injectors are. You can change your wires too.

Weight reduction..... Lose the sub. Strip the trunk, get rid of anything that isnt necessary for the car to run and be legal. Check out the weight reduction thread.

I knew someone was going to say lose the sub


You are right.....this could be the end of my love of car audio since it seems to cost me so much money.....

I got 35+ mpg with my automatic F22A1 (mods are H23 intake manifold, extra IAB spacer plate, 2.25" catbacke exhaust, PT6 ecu) with a FULLY loaded trunk and back seat and two passengers up front. Obviously, this was all highway. In town, I get about 27-28mpg.

Change your plug wires, distributor cap, rotor, spark plugs, fuel filter, make sure your ignition timing is correct, also make sure your transmission kick down cable is set correctly.

This is a f22a4 90 honda EX auto. I know shit about cars, but I do what I can, I'll change the spark plug wires and check cap/rotor.fuel filter is a little bit above my technical skill I fear...

I only use 100% gas also, I avoid stations with ethanol added into gas like the plague.

The fuel filters on these cars are rather simple, here is a link to a DIY: http://www.cb7tuner.com/vbb/showthre...ht=fuel+filter

Cap and rotor are easy. You just unscrew the 3 screws from the plastic cap on the distributor, and pull it off. Then pry the rotor off (it will be a black plastic circle shaped object on the shaft). Installation with the new parts is just reverse of removal.

Be sure to do your plug wires one at a time so you don't get the order messed up.

hey thanks a million man! Learning all the time, I already did the IACV/FITV cleaning in DIY.

can we run 5w20 in our engines even though it recommends 5w30?

a proper valve adjustment is often overlooked and wil help mpg's as well as give the car more power, run smoother,and more quiet. later.

Ah yes, that was the other thing I was trying to think of!

It made a surprising difference in how much low end power my car had.

I was told by my mechanic who worked at honda as a supervisor for 18 years that honda turned 5w30 spec into "now in 2008 it should really be using 5w20". Kinda backdating the SPECS of the recommended oil from what I understand, 5w30 was recommended in 1990, now its officially changed by honda to 5w20 to keep up MPG requires as stated by our government.

I don't much care for thin oil in old motors. Aside from making leaks a little more pronounced, you've gotta consider that the bearing clearances are a little looser than they were 18 years/200k miles ago

damm you cry over gas mileage over a honda? get a bmw, then we'll talk.

WTF dude? He's just asking how to get the best milage. Your post was absolutely worthless.
