    Default MPG adjustment on Op.com

    Has anyone fiddled with the MPG adjustment on Op.com? On the BC, it'll show ,say 47mpg but on paper it'll be 41mpg. I've adjusted the figure down twice after my last fill ups (once I worked out the actual mpg on paper), but can't seem to get the BC's mpg close to the actual mpg.

    Anyone had any success?

    Trip computers are notoriously inaccurate. I think its something you have to accept. My friends Audi is about 20% optomistic compared to working it out on paper and the dealer says thats normal!!
