Had my car 6 months. 2010 1.6 focus.
When I first got it I would fill up to the max and millage would say 393 miles left.
After a can of bkg44 I think it's called and using v power and tesco 99 a few times, when I fill up with normal fuel I get 410 miles left ?
Coincidence? Or could the trip computer be a bit liberal in its guess work?
Thought I'd ask.
