they say the camshaft and "pushers?" dont like synthetic, that the camshaft would be WORN , and the cylinders will be like GLASSED surface...

ive tried Fully Synthetic oil 5w40, but it just dissapeared.. the engine started consume oil..


but now it is newly rebuild so =) maybe it works better? new oversized pistons and bored 0.5mm... =) it works really fine now =)
