Get an A in ALL fuel mode levels.

Fuel mode is the easiest mode, sometimes even more than Story mode. You can take your time on almost all levels (very few have timers) and coast from goal to goal. Some levels are very unforgiving in that you need to use tiny little spurts of acceleration and float/coast nearly the entire time. Try not to land as it requires more fuel to take off again. Instead float and coast through the goals.

I suggest doing Fuel mode second after Story. The reason for this is because it teaches you better handling and the ability to go slow. Once again, the most difficult level is probably the second last Pizza stage. Same reasons as before; you have a bunch of UFO lasers chasing you and you'e trying to conserve fuel. I did not need to do a bonus platform for the A rank though, unlike Health mode.
