Engine Oil Debate?!
Posted 13 October 2003 - 11:12 PM
I have a 92 Loyale that suffered from the "clacking engine" problem. Following this groups advice I used "Marvelous Mystery Oil" and (for the winter) added a light weight oil (5w30)
Now I wonder that the oil may be too thin and that many of you
suggest 20w50 as the heavier oil will help the oil pressure, and the MMO will thin it down to be just right.
What's the best oil weight to use?
What's the best brand?
How much MMO is enough?
Can I use MMO at each oil change?

Stick to one brand per change, and just find out what viscosity range stops the clacking. Higher than 10w-XX is probably not a good idea for winter use, your pump will be stressed at cold starts.

I've used 4 quarts 20w50 with half a quart (16oz) of MMO, and this seams to be a popular one... mostly for the EA82 boys with weird lifter/oil pump problems.

Course, I DO have the advantage of a heated garage, which I believe does more to keep a northern states engine alive than anything!
