Didn't they have one grade higher than that? If I remember correctly, I thought they had a 280? which I think was like 105 octane, at the pump, for 30-35 cents/gal.quote:

Yep, that's my average MPG in my daily commuting, which puts me through some brutal traffic jams! On a pure highway run I can get over 32 MPG no problem, even with the car being automatic with the optional 3.15 gears. I can't wait to get a C6 someday, they get even better mileage even with having 400hp! The new 6 speed automatic has a 2.56 rear end gear and it's 6th gear ratio is .67. (compare that to my 3.15 ratio with a .70 overdrive and you can see it's a significant drop in highway cruising rpm)quote:

Patman, I hope that is your combined or even mostly city mpg. I get up to 32 mpg on the hwy. and over 20 city. This is with 4.10s, but an M6 (6 speed manual for those who don't know what we're talking about) and not exactly taking it easy. I would think that your car's much better cd (like .28 or so vs. my .32) could make up for your auto trans vs. my manual trans f body, as far as mileage goes?? On top of which your car is lighter by a minimum of 175#! (I have a no option hardtop Z28.)
Tell him to send it my way for a few weeks, I'll be sure to put some miles on that yellow beast!quote:

Patman; that is pretty good considering your driving conditions. I see your point about the C6. I will ask my brother to check the mileage on his once he's broken it in, if he ever does break it in, since he does not drive that thing enough, IMO.
