The most gas I ever fit in:
I decided to go 30 miles AFTER the last bar started blinking and see how much gas would fit. I always fill at the slowest rate and allow the pump to auto-shutoff. This time I even did it manually and added the last gallon even slower, MAYBE this helped?
I rounded up only 6 cents to make an even $15.00. I would never top off any more than this (also I do believe it's not good to suck the bottom gas out of the tank), but I got obsessed with seeing how far I could go!
Does anyone recall that Seinfeld episode where Kramer, and the car dealer, run the car on fumes just to see how far it will go??? LOL
My display was reading 48.3MPG with 406 miles driven = 9.38 gallons fit in.
