My 86 4runner is not getting very good gas milage at all. Its getting about 130-140 miles to a full tank and there is no leaks anywhere and seems to run great anyone have any tips on fixing or improving gas milage?

dont speed, dont punch the gas, shift early...

Kiroshu

no dude i drive it normaly its a 5-speed and i usually shift it around 3rpm or less trust me its somethin else.

haha i have the same problem just in a 95 pickup...ive been wondering the same thing, yes i do drive the SH** out of it, but it seems like im getting horrible gas mileage.

Kiroshu

It has the following new parts on it that could contribute to this:
New Spark Plugs
New Spark Plug wires
New Distriubtor cap
New Rotor button
New Coil
New Fuel Filter
New Fuel Pump
New Air filter

Soo... I'm at a loss for what else to tweek...

Kiroshu

Yea man i dunno I thought it might be emissions but its not throwin any codes so yea...

I usually upshift around 1500 and get around 22 mpg with my 88 / 22re... have pulled 350 miles out of a tank

Kiroshu

Well like i said i usually shift bellow 3 depending on whats going on in traffic. I've have 2 V6 5-speeds and drove them the same way i've drive my truck now and gotten 250miles out of thier tanks....so yea but still my truck gets like alittle over 100 miles out of a tank and its empty...

Kiroshu

I'm sure shifting it 1000 less with not give me 250 more miles to my tank either....

abecedarian

Well, you haven't tried...
... so ....
I guess aggressively driving my Firebird and getting about 10 mpg, then being light on the throttle and getting nearly 20 means nothing... after all, it's a 400 cubic inch V8, not a 2.4 Litre 4 cylinder.

Kiroshu

.....dude when ive had v6's that got better gas mialge and drove them the same way normally its not the freakin driver. I had an 88 3.0 5-speed 4runner and it got about 240-270 miles to a tank which is good for a v6 and it had 289,000 Miles on it. My truck i drive now the gray one in pic, i drive exact same way as my old 88 3.0 and its only getting me alittle over 100 miles to a tank no leaks of fuel. so yea. Gearing up at around 2000-2500 rpm

abecedarian

so you have a truck that burns some extra fuel. I'm guessing you have checked your timing, plug gaps, compression... no?

Your cold start injector isn't leaking?

Should I continue?

Kiroshu

Timing is perfect and plugs as well, compression i have not checked due to lack of equipment. If the compressions off its not by much cause it runs superb

I've driven a 2cyl engine that gets anywhere between 5 mpg and 40 mpg (depending on how it's driven) and you're gonna tell me that by default a 4cyl should get better mileage than a 6 cyl?

Kiroshu

If they are droven the same way in the same condtions in the same town same trips same area and same tune-ups i would make a rough prediction yes.

abecedarian

I can cruise around all day on my CX500-TC and get 40 mpg. When it comes down to it and I want to womp on a ZX7, I get 5 MPG.

abecedarian

In a nutshell- generalizatons are just that- generalized.

Kiroshu

Your really not helping one bit at all.....you do know that right?

abecedarian

I appreciate the argument but it's led us nowhere.

I can get 20 MPG out of my 88 (my avatar) driving around town. I shift early and don't hit the throttle hard.

Maybe the fact I'm anal-retentive about timing, TPS adjustments, etc. helps.

Kiroshu

eh well I supose i could try going easier on the old girl since shes pretty old and high miles. I think i'll try shifting earlier and seeing if i get a difference...
