Weighty Matters

Posted by Dakota Jim on August 07, 2004 at 21:19:40 from (152.163.253.103):

I have a tractor that runs just fine. The only problem is that if I work it hard and then cut it back to an idle it seems to have low oil pressure for a few minutes before it comes back up. I assume this is because the oil is thinner. It didn't used to do this. It's pretty old but I don't use it much and I really don't see a major job being necessary to keeping it going satisfactorily. I have been running straight 30 weight in it for thickness reasons to keep up the pressure and that seems to help a little.
But....I have read recently quite a bit about oils and their various weights. The consensus seems to be that most of the wear occurs at start up and I gathered that thinner oils are better in that regard. My question is: Am I better off to run straight 30 weight so it holds better pressure or should I run 10/30 weight for reasons of thinner viscosity at start up? I really don't understand if it is as thick as 10 weight or 30 weight. Will I lose the thickness advantage of a straight weight by using a multi weight? Can some one bring me up to speed?
