I have a 1999 BMW 528i, and the Fuel MPG use to read at 5.9, I took it in for service and now it reads at 17.5. I was told that is should be reading at 20.0 or above. I would like to know if anybody knows what exactly the FUEL MPG should be reading out.

I also put a full tank of gas in the car and the total millege that registered was 289 mpg, should I be getting at lease 300?

If somebody can help me with this, that would be great.

Thanks

you need to reset the mpg meter to start an acurate reading of your driving style check your owners manual on how to.
