So recently, I entered a fill up for my truck, and when I looked at the calculated mpg there is no way it calculated it correctly. Trip miles were 223.1. Data requested is miles since last fill-up. Cost per gallon was entered, at $2.669.
Total gallons was 16.710. now someone please explain to me how 16.710 gallons used in 223.1 miles calculated to 22mpg, which is what fuelly is trying to tell me.
