Anyone noticed a difference in mpg this last week or so?
I have not driven my car for 3 weeks as I get a company van every other week, got back in it last Friday run around on fumes for a day the fueled with bp ultimate. Since filling the obc is showing 34 mpg where as on shell v power it struggles with 30-31mpg normally and my driving has not changed I don't think.

I know the obc is not very good to go on, but overall it's pretty accurate when worked out on a tank to tank full up.

Just curious if its weather or fuel quality related? I assume the temperature increase has made a difference but its quite suprised me, to some it might be minimal but to me it's alot

Yeah I've notice an improvement now the weather has warmed up....

Higher ambient temperatures will be causing this to be noticed.

It's definitely made a difference or a mix of both, either way it's good

Lol I've noticed a big difference this week too its as if its ran on fumes all week so far as normally I'd have used like a quarter of a tank and its only used half of that and I've hammered it everywhere

Normally stop using winter fuel in April too, that will see a good couple of mpg gain.

Yeah I agree, I did that, few ice cubes in the tank, couple of mint leaves, the car loves it.
