Jason, Dave's cam pitting was with the Amsoil. He doesn't use Amsoil anymore....
No doubt Amsoil is into the MC market. And they have had a great rep for a long time with motoryclists. But, for the price is it worth it when there's horror stories like what happened to terrebandit's Bandit. Read Dave's link above, he did a good job of documenting the experience. I remember when he went through that ordeal and it was a nightmare.
All BA's prior surveys tend to support the following favorites:
Syntheitcs:
Shell ROTELLA T Synthetic 5W-40
Mobil 1
Dino Oils:
Castrol GTX 20w-50 or 10w-40.
The most popular has been GTX 20w-50. Motorcyclists in all walks of life have been using this in their bikes for decades with great results...
Eventhough Synthetics get rave reviews by customers and are praised by oil company supporters. Is it really needed when you're gonna change your oil regularly anyway? and a good dino has always been fine until synthetics appeared in the market... My opinion: is it probably is a better product, but why use it when its overkill and a wallet drainer. Is my engine going to jump and scream "Oh boy, Synthetic ! Wahoo!"... Doubt it, unless I'm using a race engine on a drag strip redlining every shift nd changing it after every race day....
If you really have to have synthetic, try Shell Rotella T 5w-40.
Another plus is Walmart carries it by the gallon...
If you wanna use what motorcyclists have proven works in terms of wide spread use and success proven through the ages, try Castrol GTX 20w-50.
It's cheap, and can be purchased at Walmart by the quart or gallon.
The most important thing is change your oil and filter regularly, and don't use paper based filter like fram or reuse oil filters.
Good luck on your info quest... There is so much info on the subject it's clouded, confusing, promotional based, etc... it's mind numbing...
