i've been in the nitro racing offroad scene for 15 years and now i'm wondering why massive has come back with excuses of why an engine's crankshaft will go rusty. its only gone rusty since using massive fuel. it never went rusty while i was using AT fuel or when i was using the original cool power all those years ago. i have always run the engine dry and have always used after run . the only change is that i am now using massive's fuel.
i'm not attacking any one i'm just stating the facts.
