I have been waiting to get a longer run with FC but, i'm now getting about 24.5 mpg hwy and 21.5 city.Before, I was getting 22 hwy and 18-19 city. However I am also about 1500 mi into RX rinse (2 treatments) cycle. Have been using Molabrew w outlaw. I can't tell you whats caused increase in milage but it is definately better. I've had this car for 16 mos and the milage has always been the before numbers consistently. My car only has 87,000 mi. 86 Acura Legend V-6
