on a gentle run you can get 25 ish MPG, but get about 5MPG on a track. so from 100-200 miles per tank, (if you can get it full which is an art in itself.
Let's see, 150 mile commute and have it fill up once. That was around 90 miles just under 3/4 slurped out. Taking it easy. Gentle drive up the beacons, 50 miles or so bye bye tank.
I've made it the 200 miles to the Fest on a tankful before. 13 gallons at 20mpg is a theoretical 260 miles range. To be fair, 20mpg is a bit theoretical as well I think my average is 18mpg.
I once got 180 miles out of £40 on my 350 but that was when fuel was not as costly as it is now, lucky if i get 140 miles for that cost now.Have gone to the wedge fest on less than a tank though and that was 165 miles.
Topped up to the brim I can get about 180 miles to a tank when touring in France .... Driving around the UK, 200 ish. That is with filling right to the brim of the filler, giving the car a shake to make sure no air locks in the second tank.
