I was at this place that sells and regrinds cams and they had a sign up that said non detergent oil is a camshaft killer. Why would this be? and if it is bad, is it okay to use for break in then switch back to detergent oil?

 

what oil is non detergent?
i though all oil r detergent.

 

Why would you want to run a non detergent oil anyway?

 

its used to break in engines that have been built in a clean room.

 

only clean rooms? i thought that everyone uses it to break in their motors. anyways any ideas why its bad for cams? its gotta be something to do with the detergent oil getting rid of the **** in there

 

If it wasn't built in a clean room, you really want detergents. Otherwise all the dust is not going to get picked up by the oil.

 

ic so anyone on why this could be bad for cams?
