12 1/2% Nitro, good fuel, all we used to run in the BVM ducted fan engines years ago.

K&B 100= 5%

K&B 1000- 25%

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

From the K&B 45 ducted fan engine owner's guide:


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.
