i don't need to but i am starting to keep a very detailed spread sheet with all info like hours, gallons, miles, costs, etc. when i fill up and it would be alot easier to read the hours when it is running while i am filling up because i don't usually turn my truck off when i fill up. sorry for being long winded. i did figure i would not be able to read it whuile it was running so thank yall for your info
