I'm sure this has probably been done before, but it'll be interesting to see what the regulars get.
I'm not talking about MPG - I'm talking about how many miles you get out of your tank when you fill up until you refill.
No diesel comments please

I put in £63 of Optimax a couple of days ago which was almost exactly 50L of petrol. On my clock I had 277 when I reset it.
About 200 of those miles were driven round the highlands with a pretty heavy foot. The rest were start / stop town miles.
