From AMSOIL.com http://www.amsoil.com/faqs/faq8.aspx?zo=1132530
Although AMSOIL has publicly stated that its XL motor oils are Group III based and its other motor oils are PAO based, specific formulary information beyond that is exclusive and proprietary. AMSOIL views synthetic base oils the same as it views additives.

The XL line is GRPIII and the others are PAO.

Don't forget about the AMSOIL MCV 20w-50 Motorcycle Oil, great stuff.

All this hocus pocus about base content is going to eventually hit the Ralph Naders of the world that realize in about 100,000 miles or so that their engines are worn more than expected after paying premium oil prices and are upset and want to do something about it.

It will be almost impossilbe to remove the Mobil 1 oil cap from the Porsche. Same with the BMW. Castrol has all the OEM business.

We supply all the BMW dealers in Indiana with their BMW oil which Castrol fills...

I think we can debate this forever and really never know the long-term effects, if any. I choose to continue to use Mobil 1 in my Avalon and Denali (5W30) and in my 496 MAG (15W50) regardless of their base content. As long as I use the proper weight and change it regularly I cannot see ever having an oil related engine failure.

I havn't read this thread in awhile. What's the consensus on using mobil gold cap for a 502 and should mobil's gear oil be used instead of merc drive oil? Haven't looked at this thread all winter, things might have changed in 58 pages :)

At this point M-1 V-twin 20W-50 would be the logical choice.

Drive oil results are mixed and M-1 works well but so does Mercury.

Hydro, are you based here in Detroit??

also what about Schaeffers?? My dad and I run it in our vehicles..

he has 235k on a 98 lincoln 4.6 32V...and changes it at 9k

I love their product. It seems like it does not get enough run about how good it is???

Great Info here

I know the diesel guys love Schaeffers. I tried their synthetic grease once and it separated too much. I would get a face full of oil out of my grease gun trying to grease my truck. All greases separate some but this stuff was terrible.

This analysis was after changing the oil at 50 hours (20 hours on the oil)

Oil in both engines fell out of grade. When a 20w50 is new the 210 value should be between 85 and 110 SUS. One engine is 79.5 SUS and the other is 84.4 SUS. The latter viscosity being better than the first test.

So scratch the 20-50 gold cap, and go to the v-twin oil instead? Is the V-twin oil that much better?
