I got the gas from a Conoco/Phillips 66, and put in 88 octane, No Ethanol.

I'm wondering if the computer knows what kind of gas is being used???, sounds like a really weird question but everytime I would fill up it would only say about 430-450.....about 2weeks ago I got 570!? And when the tank actually finished I got about 555! And this was half hypermilling, and half driving a little more aggressive

Wow almost 36mpg!

 

I've cracked well into the 500+ range on road trips where I'm running 60 or under (non interstate). I've had the DIC showing 38+ on those trips(flat roads), but that is without A/C and once you hit hills and such, it drops.

Living where I live, it's hard to find flat level roads.

 

Cant wait till we get the non ethanol gas up our way
"some say" the fastracs up here will carry non ethanol high octane only
