just got back from a trip went 488 miles round trip some city driving and rest highway used 20 gals avg. 24.4 mpg. i had just put in a K N air filter .seems it might have helped a little as i usaully get around 22 -23 on this stretch of road. going on a longer trip next month will check it again. this is going about 65-75 mph. i re-set the computer while driving and car said i was getting 26 -27 mpg so anyone who does that is not getting a true sample. always use miles divided by gallons to get a true mpg.and best to use 3 to 4 tanks to get a good avg.
