I got 330 miles on a full tank one time, and that was the day i bought it driving it home. Since then, I've been getting any where from 210-250. I dont really vtec it too much, but then again, I do have fun on the backroads of VA. But I think the weather defintely plays a big role on our MPG.

i filled up today and got 300 miles to the tank. It only took me 10 gallon to fill up so that makes it 30 mpg. I do a lot of highway driving. This was with occasional burst in vtec. Normally, I get 26.5-27 mpg. I log my mpg on every fill up. Pretty good I must say.

I usually get 210-230, i usually run it to the last bar. Fill up about 10.5-11 gallons. Which is not too bad 20+ mpg.

On my supra i was happy to get 14+ mpg, good looking supra, crazysupratt! Are you on the supraforums? My sn is hkssupra91 on supraforums. I miss my 1jz.

Something that you guys have to remember when the ambient air temp drops the air is more dense. Hense you use more gas getting the denser air to burn. Thats why you lose gas mileage.

yup I am

on my supra, the best I got was 25 mpg, this was going to Las Vegas for SILV06. Just highway driving and not in boost. I couldn't belive it. I normally get 18 mpg on it with mix of city/highway with occassional boosting

hmm,

Well I knew ethanol and the cold air would make a difference, but ethanol has been in the pumps for a few months and soo has the cold air.

I woulda noticed it if those two things did make a drastic change. I guess i'll see when the weather changes...

maybe i'll try a tornado ! or atleast some fuel injector cleaner...my S has wayyyy too many miles...
