I have to admit my gas mileage isnt the greatest. I may be a lead foot at times which will decrease my fuel economy but I still think it could be better. Right now im averaging 20 miles to the gallon including both city and highway. Someone told me that with older vehicles such as mine with 150,000 94 Accord that I change the oil more often such as every 2 months my fuel economy will be better because the oil is cleaner and more like new. Then I thought of loss compression which will also make a difference in fuel economy. So I put engine restorer in there and im about to put another can on my next oil change. Other than doing those two things what I can I do. Ive also used fuel injection cleaner and seems to help a little bit but im still not completley satisfied. Any ideas?

 

150 000 miles is quite high. Usually, when you want to make fuel consumption better you will:

1. give it a complete tune up, including plugs, wires, filters, tire air pressure...
2. try fuel injector cleaner, if not, you may clean them yourself.
3. Try a higher quality fuel. not higher octane, but higher quality.
4. examine coil for possible problems.
5. examine cat for possible problems.
6. examine fuel lines for leaks.
7. examine coolant for proper mixture
8. Timing
9. examine how fast you drive at high speed.

On older cars, the above will bring your numbers up a bit. But it may also be that your engine is getting a bit tired.

You can also try cleaning your EGR ports. That may help a bit.

1. I just recently did a tune including distributor cap, spark plugs and spark plug wires.
2. Ive been using Gumout fuel injection cleaner and seems to help a bit
3. What do you mean by higher quality fuel. I use Shell oil and it seems to be pretty reliable.
9. Highway speeds I drive normally around 75-80 mph on average


4-8 Ill have to check those....

 

I get about 320-330 out of a tank with "spirited driving." So given that the car's range is 370 with an auto tranny and I've got 135K that's not too bad.

 

do a compression check. could be leaking more oil/compression than normal; new o2 sensor should help also and, get the ignition timing at 17o to 19o before tdc

 

27 in the city here in my 91 LX....254,xxx miles on it. In july, I hit 34 miles per gallon on my trip to Myrtle Beach...that was with the air running and cruising at 70.

 

man you guys are getting pretty decent mileage. i'm only getting around 300 a tank and i never rev above 3,000rpm.

 

I have the same problem as hondaracin24 does. I have a 94' EX Sedan with the auto tranny and 160k on the clock. I'm lucky to get more than 300miles to a full-tank. And I only run Chevron or EXXON gas. I have done just about everything I could imagine to better my gas mileage. I've even gone as far as to have the valves adjusted by the dealer. I atttemped the fuel-filter but the dealer told me its a "lifetime" fuel-filter and you need a special tool to remove it. I personally think its because of the 4spd auto is the reason we get such crappy mileage.

 

my compression is good, I don't burn or leak any oil, and I mostly drive in the city with a lot of accelerating/stop and go stuff.
my gas gauge is not working right, but the gas light comes on at about 300 miles if I'm taking it easy........if I'm stepping on it, it comes on at about 260-280 miles. Depending on how I'm driving I've estimated my gas mileage to be from 17mpg on the low side, to 25mpg on the high side.
The more I read, them more this looks normal for automatic 94-95 accord ex sedans.

 

Same stuff with me. I did fuel filter,air filter, plugs, wires, cap, rotor, and a bunch of fuel injection cleaner. I do step on it a good bit, so i come out to around 320 on the 17 gallons.

yeah me to.........I think it's normal. It sounds like the guys who get 350-400 on one tank must have 5 speed manuals with mostly highway miles.

 

I have a 94 LX with 170,000 miles on her and I've always averaged about 300 to 350 miles to a tank. The most I've ever gotten was 450 miles using cruise control and running an interstate the whole tank. Yours sounds about right, with a little thought about driving habits, you may be able to squeeze a little more out of her than 300. We all have different habits that makes our miles differ.

also the lx gets better gas mileage than the ex cause the ex has the vtec motor, and vtec can kick in at any point in the rpm band as long as there's wot......but I'm new to accords so I'm just going by what I have read.

You're new to accords and totally wrong.

First, it doesn't "kick in" at any RPM as long as there is WOT. You obviously have no idea the purpose of VTEC.

And it's the SOHC VTEC...we're not talking DOHC which is much more performance oriented. SOHC VTEC is basically for improved gas mileage without sacrificing driveability.

In the future, if you don't know what you are talking about, you should refrain from posting. It just leads to misinformation.

thanks for the correction but next time (or in the future) save the attitude cause if you read my post it says:

I didn't state it as absolute fact, and last time I checked the rules it states if you are not sure of something, make sure to state that it's not for sure, so don't be a DICK.... cause people like yourself that don't know how to speak to people are more of a problem to HT than people who are unsure of their information.
again thanks for the correction, and I do know the purpose of vtec.....I didn't know that it was for the purpose in the accord that it is in the civic vx (fuel economy)

oh, and by reading, I mean reputable sources, likes edmunds:

More importantly, the EX's engine featured Honda's "VTEC" (Variable valve Timing and lift, Electronic Control) system. VTEC promoted more efficient "breathing" at all engine speeds, meaning there was plenty of power available at low rpm, as well as a satisfying rush as the tach needle sped toward redline </TD></TR></TABLE>

but you probably know more than they do, so forgive my ignorance since I don't have access to your sources of information.

LOL, the point of my post is to tell you that you were misinforming people. Why even bothering posting if you're not sure of what you are talking about?

Go back to edmunds.com and see if you can find another answer...

how's that working for you?
do you need to have the last word? Go ahead, I won't respond to you again.
(hey, at least it works with my 5th graders, they like to have the last word too)
Take care

The words of a person who knows he is wrong and intellectually outdone.

 

so anyway,
I'm going to try a tip a guy at the local gas station gave me, he said that with his accord he get's good gas mileage by using the cruise control whenever possible, and doing the speed limits.
I'm going to check what kind of gas mileage I get for a tank this week by doing it that way.

 

vtec can engage as low as 2300rpm with wide open throttle and enough speed.

What a genius!!!

 

Lay off him already. He admitted he was wrong and he even said he wasn't sure about it in his original post so let it go.
