I'm back, ok, ha ha, you have 5% Nitro fuel. Unlucky! Ok, heres what I would do:

Go on modelsport now and order a gallon of the 30% Big Bang Model Technics fuel.
Go outside, lay your crapp 5% fuel on the ground in a funky pattern (I would make the outline of a "Z" like in the Mask of Zorrow film [8D]), then, get a match, place the match to the fuel and stand back... Nitro burns a cool colour... Seriously dude, don't even bother finishing off your 5%. It should be illegal to use anything weaker than 20% in a car!. lol
