Out of curiosity, I decided to start...one tank so far came out to 13.71mpg, with about 50 miles of highway time @ 70mph, two dyno pulls to 5k rpm, and a bottle of Lucas fuel injector cleaner, with another 100mi of in-town driving, much of which had a heavy right foot. The last tank had no highway drives and colder weather, but less of a lead foot...but still only came out to 12.71. Ouch. I really need to get that clutch fan...

What are you guys getting? Post some car specs and driving style...
