40W oil causing wear problems over 30w?
Many seem to disagree on the pelube issue. But I agree it can't hurt.
only "hammer mechanics" disagree on prelube. race engines are always prelubed.
wanna hear the difference? start your unrun overnight engine with the engine
compartment open and listen to the sounds you hear. let the engine warm up,
shut it down and restart, listening again. One hell of a difference in sounds.
