Replying to: bolivar (Feb 23, 2007 4:49 pm) Gas mileage is awesome mainly because of the tall 6th gear. Z06 here, and I routinely get 27+ at 70-80 mph. Followed my sons towing a race car on a trailer to Michigan (interstates), average about 60mph---got 32+ mpg. I DO drive an economy car!

Replying to: bolivar (Feb 23, 2007 4:49 pm) I think having a C5 vs. 400hp Z06 or C6 gives just another little advantage in MPG. I've gotten 30mpg on the DIC going from Fernley, NV back to the SF bay area, now admittedly that is a lot of down hill but I wasn't going slow either. Best mileage using the calc and refills was 28.5 for a 500 mile round trip out to Yosemite and back. Then again I get around 7mpg when I go on track. My local average DIC is usually 22/24 with both freeway and local streets, gosh, sitting at lights will kill mileage. Randy Replies to this message: jiminthehills (May 22, 2007 8:10 am)

Replying to: richbf2 (Feb 22, 2007 8:24 pm) The 28 mpg on the highway is a realistic number, HaHave occassionally done better with cruise control on even with the top down in my 2006. Replies to this message: starrow68 (Mar 02, 2007 9:30 pm)

Replying to: starrow68 (Feb 28, 2007 8:44 am) "...gosh, sitting at lights will kill mileage."   I had to laugh at that one...I thought the same thing just idleing while getting out to get the mail from the mailbox. After I got back in the car a couple minutes later, the DIC dropped a half a mile per gallon average....   My 2004 Z06 seems to get a tad less than you folks have described here on the freeway. I'm running 32PSI in the tires, too.   On a recent trip to Vegas from the LA area, I averaged 27 on the way there vs 27.7 on the way back, doing 70 to 80 MPH. The ambient temperature on the way back was from 95 to 60 degrees, with a slight headwind leaving Vegas.   Since there wasn't anything else to do but watch the rear-view mirror and the other poor guys being pulled over by the CHP, I started experimenting w/ trying to maximize the mileage. The difference on the way back could be attributed to running in neutral on the down-hill sections to see what that might do.   All in all, it's one fine economy car!!!   (I should add that the A/C was on most of the time, although I even experimented w/ turning that off on the steepest up-hill sections, too.)

I have a 04 coupe with automatic tranny. Out the door of the showroom the car averaged 31 mpg at highway speed. If I run between 65-70 I alway average over 30. We don't need no stinkin hybrids. Around town I am running about 25 mpg, but of course, I am usually doing cruising in this car. See you at the Woodward Dream Cruise.

Holy cow, I couldn't believe it but on a 250 mile trip (speeds between 50 and 100, 100 only briefly) I got 31 MPG. Tires just all aired up to 33 psi and a new air filter. Can you say economy car!

Replying to: vettever (Oct 15, 2007 9:42 am) Now mileage is all about set up and the 6sp C5 or C6 is going to do amazing things. In my stock engine C5 coupe at 1500 rpm I'm doing just below 70mph and gettin just over 30mpg.   Yesterday I drove two hours to Thunderhill Raceway (137miles) and got 31mpg on the tank I left with when filling up at the last station before the track. I then got about 7.5mpg for the 100+ track miles I did and again got 30+ on the way home.

Replying to: vettever (Oct 15, 2007 9:42 am) I wouldn't run at 33lbs cold pressure.   What I've read, you are going to get significant wear in the center of the tires if you constantly run this high a pressure.   The recommended 30 is better.   Oh, and I recently set a new record for my car. In the southern Colorado mountains, from Durango north at speeds of about 45mph, for about half a tank, I got 33mpg! Another half tank on the trip gave 32mph. No AC, much of this was downhill out of the mountains. Replies to this message: starrow68 (Oct 28, 2007 4:52 pm)
