Gas Mileage!

[JTM]

So my 91' Accord isn't getting the MPG it should be. I get about a little over 200 miles a tank, and sometimes worse. I don't drive crazy, very moderate in my opinion, but I don't do highway driving much. Some stop and go, but moderate. My cousin has a 90' Ex and he gets over 300 easily. So what should I check. I've check air filter, tire pressure etc. I want to replace the fuel filter, but where is it located? a pic would be appreciated.

any check engine lights....i would start with a full tune up

sparkplugs, sparkplug wires, distributor cap and rotor, fuel filter,pcv,air filter,change fluids.....etc,etc.....properly inflated tires

pcv?

What exactly is the pcv valve?
I've got bad mileage too, about 20 mpg, I should be getting at least 25 with the kind of driving I do. How do I check the pcv valve?

PVC is that circle thing that goes into your valve cover and has a thick vaccum hose that goes to the intake manny.

just unplug it from the hose and shake it. if it seems like something is loose inside, then that means it's working.

Are you kidding? Im only getting 350 KMS.. whch is 217 miles... maybe a bit more, but not much... i thought that was good fuel milage.. i replaced just about everything i can think of other then the cap and rotor... PCV valve is just about brand new too -.-

well once on the way to california, i got 367miles on 12.65 gallons but most of the time i'm lucky if i get 300 to a tank, MPT people not MPG lol

No!!! I do a lot of higway driving

Must be why... im always runnin around in the city.

on my first CB that i took, on the drive home(all Highway) i got 33-34mpg the whole way. Thats over 500 per tank. I could've went farther, but i didnt know how the gauge worked n all and i didnt want to risk it.

This was also will me driving a constant 80-90 mph.

I get 400 miles to a tank with my H22, about 50/50 city and highway... not all light-footed, either. The head is also damaged (damaged sparkplug threads in 1 and 3).



When you add performance mods, you often run rich. If you have an intake, header, or exhaust system on there (aftermarket stuff, obviously) you've probably decreased your mileage. The ECU sees more airflow and dumps more fuel. If you want to fix it, your best bet is to get the ECU tuned, which isn't cheap... or learn to do it yourself. Not many people here tune basic NA F22As. It's all H22, F22B, H23, or turbo.

what do you guys consider a tank? Like top it off, and drive until the light comes on? That's what I figure a tank would be. More than likely you don't drive until you break down and then look at your tripometer. Just because my light doesn't go on when I'm real low on gas (found out the hard way ), so i can only guesstimate how many miles per gallon I'm getting.
