Proper fill-up?
Just as the title implies. When you are filling your car up, do you stop when it kicks off the first shuts off, or do you top it off? Mind you, I do not have a scangauge, I just use the simple math to figure my MPG and keep it in a spreadsheet. I ask this right now particularly because I filled up on Friday or Saturday, and at the gallons when the pump first kicked off I was right around 40MPG, but I topped it off and brought it down to 37.2.
Up until this point, I usually always top it off and I run the tank pretty low. With a 13 gallon tank, I am normally refilling with at least 11 gallons.
I would like to hear from anyone regarding this. But I am very intersted in hearing from those who use a scangauge to see how accurate their gauge is with respect to gallons used and what it actually took to fill it back up to when the pump first kicks off.
