Please lets try to keep this as an oil thing only!
As many know I was on the wrenchs as an OMC and Volvo tech which brings me to the following question! I believe most all of us have noticed how warm our drives get while running on a flushette talking with -0- exhaust going through, I feel most of the temp is due to oil weight. Volvo ran 30wt for a guzillion years with great longevity, the OMC electric shift ran a thinner blend yet also with good gear life but was a crappy drive in other respects. Why do we now run these 70-90wt oils that contribute to drive temps when we have syn oils that are of lighter weights. Just an example Mobil 1 is like water but like other syns does a good job, why can't we run a high quality 30wt syn and get good results life wise and better speeds? Yes I am running Merc HiPo but switching to Spectro for better drive life.
