I been searching the net 2-3 days for the best gear lub to use on my 50 yr old Merc 200 20hp. Found some input here and other sites/forum. I don't know when synthetic oil was first made but I was thinking older vintage motors like mine real oil might be best for them instead of synthetic.
Our local Walmart and Walmart online dosen't have the 80w90 only the synthetic, local auto parts store the same no Merc. 80w90 just the High Performance synthetic. Searched more online and I see why, the oil is cost more than the syntheitic.
So is real oil better for older engines than synthetic. In my search Quicksilver HP cost more than Quicksilver synthetic.
Don't know if its true but one article said once you switch to synthetic you can't go back to real oil. Here's the link and part of the article.

"synthetic oils also cost more than conventional mineral oil, and it’s important to note that the switch, if made, is permanent. The additives in synthetic oil replace all of those in conventional motor oil, but synthetic oil also contains different molecules. These molecules work to preserve the condition of your engine while synthetic oil is being used, but if mineral oil which doesn’t have these molecules is used after the engine has adapted to synthetic, the absence of the molecules can cause engine damage."
