What kind of gas mileage are you guys getting from your mr2 turbo? I'm Getting 230miles on a full tank. Is that any good?

Uh, guys, we're talking PREMIUM!!!!!! :whatthe: Anyway, I get about 10/100 (that's 10 litres per 100kms - that's how we do it up here in the great white north!). That means the occasional flooring, but mostly conservative driving, and 100% in the city. That equates to about 30mpg I think? Maybe a little less?

One time I set my boost controller to max (about 13psi), I got about 170kms on one tank. :eek: Setting the boost control seems to make the car run rich or something, even if you're not boosting. I even use my A/F gauge to try and save gas...

Miles per tank isn't a useful measure because everyone has a different threshold for refilling. I usually wait till the warning light is solidly on, which is somewhere around 270 miles. You need to divide the miles you drove by the amount of gallons you put in at the pump.

My 93T gets me 22mpg usually, and I drive way too fast. When I take it easy I get about 25mpg.

mileage

what are you people getting city for a full tank because im getting 175 from full to a little over empty. high im getting 25mpg i might just take off my hks bov and go back to the stock bov or get the recirculating fitting. any ideas on how i can improve gas mileage because i dont have the money right now get the car dynoed and it wouldnt help because i dont have a wideband o2 sensor to tune the fuel curve. so please any ideas..

Checking miles per tank is not and cannot be accurate. Each gauge is slightly different an they do not even read incremently, ever notice it goes down faster under the 1/2 mark?
The best way to check mileage is to completely fill up, drive a majority of the tank away and fill it completely up again. I would suggest using the exact same gas pump both times.

See how many gallons it takes and then see how many miles you went.
Miles per gallon is going to give you a much better idea of where you are at, but that is not even exactly accurate.

Testing it this way, you should see 24+ mpg with highway, unboosted driving.
Driving around town and boosting a lot is going to bring that down.
I get about 28 mpg in Hyde on the higway, but I get about 7-to-11 mpg when racing.
