K&B 100= 5%
K&B 500= 10%?
K&B 1000- 25%

Dwayne is correct, that the way I remember anyway. You could get it in castor or synthetic oil.

GLOW PLUGS: This engine is designed to use our long reach glow plug (K&B Part No. 7311).
FUEL: We recommend either K&B 500 (12-1/2% nitro) or K&B 1000+ (25% nitro) fuel. K&B 500 will give your engine more economy, and longer life. K&B 1000+ will give your engine more power, less economy, and less life.
