I heard synthetic is not the way to go. Petroleum based is

Interesting enough, Mercury has gone back to petro based oils for their drives:

In our gas turbines in the power world we always uses a Mobil 1 Type senthitic oil because it would not break down with heat.
Heat is the key. Combustion engines don't develop enough heat to warrant full blown synthetic oil. At least thats what I read.Quote:

Additionally, my friends that own a large transmission/powertrain shop tell me that they can ABSOLUTELY see a major difference in the wear characteristics on the big landfill trash truck transmissions/quarry trucks/UPS truck manual gear boxes/rear differentials where they have switched to full synthetic in those shops...
I do know that without ZINC and other additives, your chance of a flat tappet cam failure is quite high ESPECIALLY in the break in period...
Thats all I know about engine/gear box oils :)
Just changed the truck oil at 3500 miles and next the RV.
2001 Ford with a 7.3 450,000 miles 15qts change oil every 10,000 and a filter in between at 5000.
Circle boat with a 509 14qts once a season unless there's something that doesn't look right.
Family jet boat 10qts once a year
All running synthetic oil
