I have a 1990 240sx fastback with only have 20-24 mpg. is that ok or hella bad that I need to rebuild? what about you guys? what you guys have on your car?

 

about the same. you should be good. i had a automatic 98 ka. with the cruize set i wasnt even getting that good.

 

I get anywhere from 22-25 mpg on bad alignment. Hopefully with an alignment and the 10k mile maintainance i'm getting soon, that'll bump up.

 

i used to get artic's mileage about 60k ago. approaching the big 100 i'm pullin 20/24. i've also got intake/exhaust/plugs/wires... i don' think they'll mess up mileage more than 1mpg or so.
These are older cars, they just don't get great mileage. it's sad that an LS1 gets 24/29.

 

My engine's approachiing the 75k mark

 

i get 24/25, stock w/ intake. not bad. could be worse

 

I get like 22/23 on a 1995 240. Nothin close to what I was told I would get. But my foot is always in the tank.

 

i used to get around 29-30mpg but since i got my ac fixed, i get around 27-28mpg. car is stock with 130k miles.

 

how can you get such high gas mileage. I dont' think the menu said that high? what gas you using? octane 91?

 

i'm using 93 & not getting that good, i need to tune my engine more!

 

That's insane! Even with A/C fixed, that's awesome. Hopefully I get that much once I get all my maintainance done.

 

yea i get around 28/30 in my 95' 240.


nice numbers i'd say

 

If I drive my car super-normal (no mountain runs, no freeway blasts, you know) I have gotten around 27-29 before, this on 87 with a 95 KA pushing over 183k miles.

But that doesn't happen anymore... I have a slipping clutch, bad tires, brand new A/C, and I usually get about 21 or so mpg (until I can tuned her up again).

BTW Arctic alignment won't stay no matter what you do until you replace that front crossmember.
