Dennis, I have read very many of your discussions on oil and I know you are very knowledgeable. Iíve seen your UOAs of Mobil 0w40 and was impressed. I couldnít however justify being overly picky and spendy with my oil if I donít take my car to redline all the time. I donít mean to step on anyoneís toes, but if youíre careful and timely I think 5w30 is OK
