I just recently bought my 2000 Honda Accord EX V6 Coupe and i just emptied my first tank of gas and i know i was drving it conservatively with ALL rpms under 3k at all times and i got a shytty 230miles on the full tank. I've seen people getting 300-400miles to the tank on modified V6s. I know my car can get at least another 70 miles out of it but there's something wrong with my car, and i dont know what. What do you think it is? What should i do? Oh, BTW, i do 75%city/25%highway driving.

How many miles to the tank are you getting in your accord? Please specify if you have the I4 or the V6.
