Inspector 1, I'm wondering ... Where does that extra fuel go?
I remember early 1970s GM cars had charcoal cannisters that would get saturated with fuel vapors. Can the extra vapors richen the mixture somehow and waste fuel?
I take it, that it's better to just fill up until the gas pump shuts itself off THE FIRST TIME when refueling? In other words, don't try to squeeze in another gallon or so.
I know in NJ (full serve only) they will top it off to the next higher dollar amount.
Tonight I filled my 300TE and got 19.5 mpg, not topping it off. I had been getting 17 mpg. I'll track this over several tankfuls to see if it's a statistical fluke. If my mileage improves, I'd rather pay $20 than $25 any day
