ive had 3 evos and even my 2.3l 500 bhp+ on a stady run 65 to 75 mph on the mway all did over 30mpg

around town depending how you drive it it can be as low as 15mpg

on track then even 5mpg is all you get

all worked out by the proper way ie filling the tank and working out how many liters off fuel ive used by the milage i have done not like most who just take a guess
