I have a 2005 ZX3 with five speed manual and I drive mostly highway and I only average 27.5 mpg and I'm not heady footed.

Damn. I should move to OR.

Gas alone would save me like $300 a year.
Cool thing keeping record of fuel consumption... I should have done the same, I don't even have my car reciepts in order, however I don't plan on selling the car anytime soon...

that made with a spreadsheet, or do you have a car maintaince Log application?

Interesting results. I kept a similar tally when I first bought my '02 ZX5. The lowest I ever had was 23mpg, all city driving, lots of idling. The best I've had was pure highway driving to Toronto, speed pegged at about 62 mph. I got 35 mpg that time. When my wife drove on the way home, we were doing about 68 mph and the milage dropped to 31 mpg. The aerodynamics really effect the Focus.

I have a 2010 ford focus sel, and just got a remote start put in at the dealer, on friday 2/4/11. I have noticed since then my mpg average is around 15 the highest it went was 19. I was getting about 25 mpg. Could they have messed something up or is it the cold, currently 4 or 5 degrees Fareinheit.

Thanks
