Let me see if I have this right.

Cold fuel is the most efficient for burn and performance.

Fuel temperature goes up after going thru the fuel filter, fuel pump, and when under pressure thru the feed rails, etc.
If a turbo is used, the atomized fuel will be warmed even more by the compressed warm air from the intercooler.
Auto fuel has a lower temp of where it will vapor lock.

On warm days I know of several people have injected engines who burn auto fuel, use the coolest tank for take off and landings.

How does the oil added to fuel in the tank affect temperature/performance of the fuel?  Does it keep it cooler?
