Currently I'm getting about 46.5mpg in my Civic. I commute 64 miles a day (probably 60% interstate, 40% city), I drive a steady 60mph on the interstate, try to coast in 5th gear down small hills, EOC on longer, bigger hills, I don't rev above 2500rpm's and try to get into 5th by 40mph. I have gutted my interior, don't use A/C, etc.... My goal is to get to 50mpg. Is this going to be achievable? What measures should I look into taking to get the extra 4mpg? My car is lowered, 40psi in all tires (may increase this as max sidewall is 51), and I try to coast as much as possible. Car recently had an oil change and air filter. Probably need to change out the plugs and fuel filter as it's been a little over a year since doing that. What other suggestions do you have for me to reach 50mpg? Oh and car has 170k on the clock, but still runs great.
