Thanks Weldangrind, I think you are right, makes sense. Of all my reading about MC's, I never heard of anything like that.
About the oil, I don't need the W in 15W40, the coldest it gets here is in the low 70's but you can't buy straight 30 or 40 weight oil.
For that matter I can't even buy Sauerkraut, not even in a can. Too bad because pork is a big thing here. LOL
