So drove up to Lake George, NY on Sunday.
I ended up having to stay on cruise control because I was cruising at 80, without even realizing it.

I filled up on 93 ( it was 3.66 a gallon)
drove 280 miles round trip
average speed DIC 68mph
average MPG 32.5 mpg

I am impressed

I have noted on the web and even yesterday another SS owner and most are getting 26-27 city and 31-32 highway.

Mine also showed these number coming from Dayton.

Not me, best I've done so far is 23.67. I've got a little over 3,000 on the clock so far.

Yeah i can't seem to get above 24 no matter how hard i try. I've only got 1100 miles. Average speed is 38 MPH. I rarely get on the gas.

That's great for a 68mph average.



55mph =37mpg
60mph=35mpg
65mph=32.5mpg
70mph=29.5mpg
75mph=25mpg
80..well i never drive that fast long enough to know.

This is what I believe youll see if you use cruise. I dont use cruise so my number will be 2-3mpg higher across the range.

Drag is everything. Speed=fuel consumption.

??? Not that driving the SS like you stole it is a bad thing, but DO YOU? Reset everything and check you highway cruise MPG's vs the ones I posted above. If that is what you see, the culprit is your foot.

You guys are simply having more fun in your SS than me. I have a 37 mph average over the last 400 miles and can't seem to keep it above 35mpg.

"Getting-on-the-gas" should be defined by your vacuum gauge going above zero. On the highway i don't let it pass above negative ten (-10) if I can help it. I 1-3-5 shift. Or 2-4/5 shift on a downhill.

I've gotten 26+ MPG on the first two tanks, doing a lot of local driving and then getting on it quite a few times recently.

I'm almost always in vacuum. Even when im first taking off it barely goes into boost. Highway i keeep it between negative 10 & negative 20.
