Fouling plugs? Update 9/2/08

[spareparts]

i used to use 100-1 amsoil synthetic blend in an old cross flow. Amsoil designed it to replace a 50-1. It worked real good, the engine idled good, but it didn't smoke enough for me, I always wondered if I had mixed the oil with the gas, or had mixed it correctly. Engine never had any issues from running it.
