M135 - costs about £50 to fill up, get about 350 miles to a tank. Does 31mpg pretty much everywhere, regardless of how its driven.

Audi A3 1.8 TFSI 160bhp

Official figure is 42mpg combined. I've only measured it once so far and it got 31.2mpg, that was a good mix of driving. Not very impressed. That was on regular unleaded.

I'm trying to run the tank down low as I dare, then I'm going to fill it up and remeasure. Will then be filling up with super unleaded (sainsburies version).

So far I've got just under quarter of a tank left and have covered 305 miles. Believe it's a 55 litre tank.

Mazda RX-7 FD still on stock twins but pushing more boost.

Costs between £60-75 depending on whether the Shell station is on or off the motorway.

I typically get 250-300 miles to a tank but do a lot of highway driving when using the car. I average anywhere between 19-24 mpg.

If I have a tank that is mostly city driving or stop and go then less than 250 miles and more likely around 15 mpg.

On the track I average about 6-7 mpg.

What a weird question?

Unleaded is currently between £1.05 and £1.31 depending where you are filling up. So that is over a 25% variation before you start.


Hence why the MPG figure is the only one that matters.

I actually prefer to see a £ per week figure though. The difference between a car doing 30mpg and one doing 40mpg sounds loads, in reality it can be such a small percentage of overall running costs that is really does make any perceived savings a nonsense, especially for those doing sub 15k miles a year.


My E350cdi used to see 33mpg calculated, my E350 petrol sees 29mpg calculated. Doing 20k miles a year it is not worth worrying about.
