I was just wondering what the accuracy of the stock instruments is like? How does it gather the MPG? Would a scanguage benefit me and if so how? I'm sure there will be more questions. Thanks for any input.
I hear the stock mpg gauge is fairly accurate (usually within 2 mpg). I'm not sure how it gathers its readings exactly. A scangauge will still be of benefit as it can monitor a lot of other things.
I know that it calculates how much gas has been used every 1/10th of a mile. I'm pretty sure it just takes how many miles you've gone and then divides that by the gallons of gas used.
I know this is probably in other threads, but while I'm at it, how much do scan gauges cost and where can I get one?
