Nothing about ultra-high viscosity oil, only an explanation of ZDDP and an advertisement for Joe Gibbs oil. Do they even make a formulation for common sump/gearbox engines (like motorcycle engines)?

ZDDP content was reduced in most motor oils because it can damage catalytic converters. It's still available as a stand-alone additive.

All Motocross/ATV engines with wet clutches XP7 also MX1 Click Here For More Info

Wow, $19/qt! Doesn't say anything about anti-shear additives or street bike use. As long as an oil doesn't contain friction modifiers, it's wet-clutch compatible.

We don't want ultra-high viscosity oil. We want oil that maintains the starting viscosity the longest.

The clutch and gears are what tear up our oil. They act like hammers on the oil molecules.

This is why Amsoil's tremendous amount of (published) testing on viscosity longevity is relevant to us as motorcyclists.

If your best dino oil loses 50% of its viscosity in 2,000 miles but the Amsoil MCF 10W40 goes 10,000 miles before even beginning to lose viscosity, which would you chose, even if the Amsoil cost three times a much?

That poor gentleman can't even pronounce dialkyldithiophosphate. I seriously doubt he's educated in the premise of it's usefulness beyond what he's told to say.

That would be a mistake,,,

Based on this advertising drivel and the gentleman's lack of familiarity I would not view my comment as a mistake. For any of us on this forum to be awarded the STLE's Certified Lubrication Specialist (CLS) rating we would simply have to state that we have 5 years in the lubrication industry and pass a three hour, 150 question multiple-choice test. That's it. (a 70% is all that's required to earn certification)

If this gentleman wants to impress then I'd love to hear his explanation of how alcohol is reacted with phosphorus pentasulfide with a neutralized resultant and then mediated with zinc oxide. This is how ZDDP protects camshafts. This guy is a goofy clown selling oil for a company that doesn't even make oil.

edit: I pulled up the STLE's directory and Mr. Lake C. Speed Jr. will lose his certification on 04-01-2013 if he doesn't re-test for renewal. Also, a small bit of research shows that this oil is formulated by Lubrizol. The CAS number for the active ingredient of the above listed oil for wet-clutch applications is 7783-06-04. This is simply hydrogen sulfide. The MSDS lists hydrogen sulfide in this product at a rate of <.1%. This is a very poor showing for lubricant that brags about their ZDDP loading and charges $19 per quart.

Don't allow yourselves to be duped guys. Stick with name brand and certified lubricants that the mfgr recommends.
