welcome to the RC craze, to get things straight, I haven't seen really anyone here with parts for that truck for sale, ever consider something more "hobby grade", like an Assocated GT2, or a HPI firestorm 10T, as for fuels, 20 is "bashers blend", and 30+ (more like 33%) is "racers blend", I can't sadly answer any other questions, but I would personally consider one of the vehicles mentioned, the one you are looking at, may look downright cool, but as for replacment parts, and being able to withsand the riggors of a beginner to RC, I think you are better off with a different vehicle[>:]
