i think temp does have an effect, as it's been getting warmer, i've been getting better gas mileageunknownsuperhero said:I get at least 300 to a tank, I have seen 340 and put in 11.6 gals (29mpg). Almost all highway right at 80 or so, even with 30 mins in traffic a day. I use 91, all the time (the highest we get around here). Maybe temp has somthing to do with it, It is around 70 in the afternoon and 50 in the morning when I leave . . . Shit the lowest I have ever seen is 240 and I was on it all the time. Nothing done to my car baut the recall and updates. Weird no one else is getting mileage like this??
Ethanol has less fuel value (BTU/gallon). Ethanol blend should be priced a couple cents lower to compensate for getting less fuel per gallon.jmichna said:...FWIW, I see a noticable difference in mileage between all gasoline and the gasoline/ethanol blends (all gasoline is better). I run 93 octane all the time.
