			Around 15-16 mpg around town, but if i mix in some freeway driving, it goes all the way to 17.   This is pretty much unchanged in my '88 Targa from the day i bought it (1992 with 4K miles on it) to today (127K miles) It's driven "rapidly", not "maniacally", no leaks. Needs a quart of oil every 1000-1200 miles, plugs always look good after major service, car is stone cold unmodified, so where's the gas been going?

			1979SC / 3.0 / 2225lbs - 20.1mpg all-time average - best of 25.9 Hoping with new induction and new EFI this year, I'll bring up both of those numbers.

			I've got a related question.  I race an '82 US SC.  I've never gotten serious about how much fuel per unit of time on the track it consumes.  Below about a quarter of the stock tank it starts cutting out on long corners, so I have to leave a margin, but want to finish just a bit above my minimum weight. Gallons per hour? Gallons per minute? Anyone calculated this for an SC on the track? | ||

 I could lean it out a little more I guess and see if that makes much difference

			32 gallons to go 703 miles equates to 22 mpg.  Stayed about 75-80 mph. Last August so 90F out. Real 2.7RS, meaning MFI with correct space cam etc.

			I was searching the forum and found this thread - interesting comment in first post. Deja vu all over again… Anyway, I wanted to post that I am getting a whopping 12 mpg around town, with some aggressive driving. UGH. Seems really poor. Top end re-build 5 yrs ago, Any smoking gun to look for? Jason
