Filled my tank brimful a few days back and have since driven 196miles, 100 of them around B roads at 50-60mph just poking about, and today another 100miles (ish) from cumbria to sunderland, with a few bags of cloths in the car, also sort of pottering, didn't get stuck in any traffic so to speak of.
Usually it pulls 40-53mpg on long runs, usually gets 44-46 I reckon on this run.
Yet average so far is 27!!!!
check my math please:-
196, filled tank just now, and 32.74litres/4.55 = 7.19gallon.
196/7.19gal =???mpg
=27.26mpg right?
What the hell happened? I did this expo as I thought it was costing me a fair bit at the pumps the last month or so. Its been running fine, maybe trying to idle to low and it feels rough when idling at normal temp, not as smooth as it used to.
Only thing that has been done was headgasket etc. I didn't skim the head at first, but stupid me being clever got a water 'weep' hardly call it a leak, so had head skimmed a week later and a new headgasket fitted.
Ever since its been burning fuel alive, but why? There isn't a smell of petrol and no leaks etc.
