Affect of fuel temperature on performance?

What is the the affect of fuel temperature on the performance of Formula One cars?

Cooler fuel can give a car a performance advantage.



It is denser, so it can take slightly less time to refuel a car or marginally more fuel can be added in the same time.



Cooler fuel would also give a slight power advantage for about three laps before returning to the temperature out on the track.



Eddie Jordan says: "If you put chilled or cool fuel into a car you get between 5 and 10 horsepower increase."



However, the total advantage for each car over the race distance is almost certainly no more than a second.

I'm sure you're referring to the cool fuel controversy that put off the World Championship results for about a month. Cool fuel has some advantages. It supposedly makes the car go faster. Over the distance of one race, it adds about 2-3 seconds of advantage. Secondly, by cooling the fuel, you can somehow manage to fit more of it into the tank. These are the effects of cool fuel.

Im not an engineer but I believe cold fuel gives a power bonus, so there's more horse power, so there's better pickup.
