Re: break in oil and afterwards
Well, I am in the same school of thinking after reading about all the cam/lifter failures. The Valvoline VR1-10w-30 has one of the highest film strengths of all the oils 540 Rat has tested (conventional) and enough sacrificial zddp as well. Seems I have to order it in, as the stores don't really have it on the shelves though. At least 540 Rat has developed a test that can rank the oils by strength and that seems to be more than the oil companies themselves have done or at least want to tell you about. I know that folks have personal preferences when it comes to oils and what has worked for them in the past and change is hard. At least more light has been shed on this topic and information is what it's all about.
