i'm not always right, its you thats always wrong
i jsut like to prove a point, i don't even know why you would want to put nitro cleaner in your engine, i've forgotten what was said, but common sense says, if nothings present, nothing can do harm, whether it removes the existing lubrication or not, as already stated fuel will go in and re-lube it before it even combusts for the first time as everybody knows the fuel goes it through the crank case anyway.
