Its as good a guide as any, but don't forget there's also a very handy little fuel gauge on the dash that actually works! When that hits the bottom line you'd best be looking for a station.So when my gauge says 60 miles till refuel. Does that mean I'm out of gas in 60 miles, or does it mean in 60 miles I get a warning light/beep, and I really have another gallon or so? I've only filled my tank once so far, and it was still at 1/4 tank.
It has been recommended to me to never use the last couple of gallons in the tank. That eventually there is sediment that can shorten the life of the engine over time. Does this make any sense?
How low?Not to me it doesn't, any sediment is always going to settle to the bottom of the tank where the fuel pick-up is located all the time whether the tank is full or otherwise. What does make sense is the fuel pump is cooled by the fuel, when the tank is extremely low it could lead to premature pump failure if repeatedly run low.
