OK, I'm running a 3.0 4runner stock with 31" tires, and I'm getting aprox 185 miles per tank.

Also, does anybody no if you will get bad millage with a bad CAT?

 

something is wrong with that mileage. with 33's and an auto i'm gettin ~215-230 per tank if i run it down low

 

I got about 205 miles to a tank with my 31's 3.0 auto with 4.56 gears however I think my cat is clogged too and I was wondering what kind of affect that has on it, I felt that i used to get better milleage when my cat did not sound like it does now

 

that is not bad at all now that i exploded my front end with 4.56 i can not wait for the 4.88 that i see you were lucky enough to have stock

 

i get about 300-310 mile per tank on my 98 3.0 auto. i run 265/75/16.

 

So, are you saying that my mileage is bad? This is why I posted this thread, to find out if I have a proble, and to maby see what you all think is causing it.

 

I get 13mpg with my 3.0 on 33 12.50 mt's and stock 4.10's

 

With alot of offroading during the tank the worst ive goten is about 11.7, but with mostly all interstate at 60-65 the best ive goten is 16.5 mpg. This is with 31's and 4.56's

 

i get 15 in my dually no matter how i drive it.
partially cuz it runs ice cold
and partially cuz its been sitting for 4 years until i started driving it

 

lol im getting about the same gas milage with 33's but i also run my truck hard.

lol

but on a good day i can hit about 200.

 

Im just above half a tank and im at 90 miles. UGH!!! Its all city driving but its not bad traffic.

 

I get 18-19 highway/city.

I once got over 19 and 1/2.

I'm running everything stock.

 

I'm just a little below half with 89 miles.

 

13-15mpg about 200mi per tank. this has never changed, ever. even with regular tune-ups, injector servicing, nothing has ever affected the gas mileage.

 

stickeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee eeeeeeeyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy yyyyyyyyyyyyy plz..............

 

Stock 1991 truck, highway is 18-19ish mpg in the winter (I think due to reformulated gas) and 21-22 highway mpg in the summer.

 

sad when a 3.0 is getting better mileage than my 22re... lol

 

x2~!!!!!

 

I get like 200 a tank if I run it really really low, on the highway. The way I usually drive, I'm at about 80 or 90 miles at the halfway mark. Ive kept a log of my mileage since I got the truck:


Maybe bad mileage is a long island thing

Edit: Keep in mind that I haven't compensated for bigger tires, the mileage is straight from the odo...still, it's horrid

 

Well I've had some work done... K&N cone filter, over size 2.5" exhaust, free flow cat and I get around 540kms [335.5miles] to a tank winter/580kms [360miles] summer.
Before I had the exhaust done I was getting around 470kms [292 miles] to a tank, when my cat got clogged it went to around 420kms [260 miles] a tank.
These numbers are from driving about 65/35 hwy/city.

When you get the cat go for a free flow performance cat... they don't cost much more and may even be less then a dealer part and make a huge difference. The 3.0 can be a relatively efficient little mill but you have to open up the intake/exhaust so it can breathe more freely.

edit: I'm riding on BFG AT 31*10.5s
