What mpg should I be getting, just picked up the rents from the airport, 100 mile round trip on the m6, in 6th, doing 50mph in a speed trap area, couldn’t get above 35mpg?
Noticed the temp gauge dropping to 0 the faster I went and go up to halfway on idle and slower speeds and occasional big waft of fuel?
Is the thermostat sensor off causing overfuelling? I’ve had to replace this on every model gti I’ve owned but never used to get to halfway?
