[Dub_Dan]

its a strange one i hope someone can shed some light on please...
my car does 580ish miles to a tank 70-75 mph motorway but it only reads 44 ish mpg is there something wrong telling the car that im doing less mpg?

thanks

That's prob about right if u use the expansion space in the tank too. If you do 65 it will be higher mpg.
