What does the rc nitro cars run on?

Question

im going to get a rc car and i want to know what fuel it runs on

Answer 1

They can actually run on up to 30% nitro fuel.  It can be purchased at your local hobby shop or online, about $25 a gallon from where I am from.  As for parts, there numerous amounts of sites out there that sell nitro RC parts, my favorite is towerhobbies.com.  

Answer 2

5%-15% Nitro. The same fuel jet planes use only a small (not pure )amount. This is a very expensive hobby. You will have to buy glow plugs and these are harder too find anymore. Especially the longer ones.
