My 8v only gets about 32mpg and I do nearly 40 miles a day Interestingly though, my coolant temp seems to hardly get above 75 and only really goes up if I've sat for about 10/15 mins. Could this be a similar problem with coolant sensor as well ?
I'VE replaced coolant temp sensor and thermostat and still getting no more than 28mpg.I did just over 80mile last night and averaged 31.7mpg.This thirsty 8v thing seems quite common now..
