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

Good link on this, remember that it does not break down..it just gets dirty..

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.

I wonder if a NASCAR runs light weight synthetic oil??

I have been running full synthetic in all of my engines for at least 10 yrs now... At first I was skeptical but after seeing how clean the oil has become between changes AND how GNARLEY the oil in my fathers engines are with CONVENTIONAL oil, Im sold...

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
