Mobil 1 Extended Performance was just made available 2/1/05. The Gold Cap is better than the Red Cap because, amongst other things,

We know that, and we know that it is a superior oil, but what we don't know is if it's properties have changed such to make it now unacceptable to use in a wet-clutch application.
The old 15w50 redcap was just fine, although Mobil would have us us only MX4T or V-Twin (at $10/qt from a cycle shop).

Personally, I'm switching to M1 Truck & SUV, probably for my Tundra as well as the bike.

I saw a oil analysis done on Extended Perfomance 10w30 and put the numbers on a post in the General section. Very few changes they made vs the old mobil 1. Zinc,Boron, Phosphorous went up and moly went up to somewhere in the 70s. I'm going to use it as I'm sure the changes to the 15w50 were simillar.
