i have an 90 runner and the gas mileage i am getting on a regular basis is terrible, i am getting between 14-15 miles per gallon. the truck has 31x10.5x15 tires on it and a 2" body lift, will either of those be part of the lack of mileage? i have recently done a tune up on the truck:
plugs
wires
cap
rotor
pcv valve
air filter

is there anything else i can do to help improve the mileage?


thanks for any help offered

Which engine do you have? If we are talking about the 3.0, 14-15 mpg is about average.

If that is city milage and V6 then like chickenlover says, thats normal. I get 18-19 highway.

A 2" body lift?? w/31 doesnt sound like it looks too good..... {No offence intended!}

:complain: Thats pritty much the best your gonna do w/that setup...

The only thing you can do to help mpg is get a small truck and put your runner up for 4x4 only

dont know if my last post went through so i will try again

sorry about not putting all the info on the truck
its a 22re with an auto tranny, and the mileage is all highway

thanks for the help

check for vacuum leaks....that and bad o2 sensor are the most common causes of crappy mileage.

consider yourself lucky to get that with the 3.0 and a 2 inch body lift. im stock and im gettin 12-13.

you oughta be getting more than that on a 22re. whats the mileage? i'd bet o2 sensor also.

I get about 19.5 MPG based on mostly highway use. That is in a 4x4 pick up, 22RE and 235/75/R15 tires.

A 4Runner might be a little less but not by 4-5 mpg.

I get about 12-14 on the highway and 10 -12 in the city with the 3.0 on a stock suspension with 31X10.50's. But then I am in dire need of a tune up and I just put on a Flowmaster exhaust.

I'm hoping with new plugs, wires, etc. and a new o2 sensor I can get up around 15 or 16.

On a different note, has anyone tried the Yokohama Geolander M/T's?

Oxygen sensor sounds like the culprit.

oxegon sensor might be the culprit. Try a sea foam treatment did wonders for my '88 22re!

'87 22R .. just actually figured out my mileage yesterday. 21.5mpg highway.

31x10.5 mud rovers movn about 70-75mph the whole time 5th gear. one tank of gas got me 330 miles.. Give or take the last gallon in the tank [below the E mark =)]

the odometer reads a little over 140,xxx but who knows if its the original cluster, the previous owner who lied about everything else told me the motor was rebuilt about 20,000 miles ago but i am starting to doubt that, as i previously stated i did a full tune up about 1.5 months ago, had the exhaust re done with a regular no name muffler but all new piping since the old had rotted through, the only thing i didnt do is the o2 sensor, it doesnt seem to have any vacuum leaks but i only looked where i knew to look, also someone had mentioned sea foam, i did a can thru the gas tank and a can thru the brake booster and didnt seem to make too much difference
