i've assumed for years, and agree with you, amzoil is a cult!

 

amzoil = snake oil!

 

I know this is an aold thread, but I thought I would chime in. I have been riding for 20 years. (I know that is just a fraction compared to some guys). I have put hard countless miles on each of my bikes. I have never had an issue with rotella. I put 30K miles on a 2003 GSXR 1000 and had hundreds of launches (Drag Racing) on that bike, and when I sold it it still had the stock clutches. I am a believer in Rotella. All of my bikes since 98 or so have ran Rotella Dino oil.

 

Couldn't find simple Rotella T, but (hesitantly) bought the Triple protection. Says "additive technology" and reduces engine wear, but meets jaso ma. Also found this if anyone is interested:

Here is the email from a Rotella engineer that I found on the Shell forums.

"We recently ran the JASO MA friction test on Rotella T with Triple Protection 15W-40, Rotella T Synthetic 5W-40 (CI-4) and our soon to be introduced (within the next 2 months) Rotella T Synthetic 5W-40 CJ-4.

All three oils passed the wet clutch friction test. Rotella T Synthetic 5W-40 (CI-4) has more than 1.2% ash (JASO MA spec limit) so it can not be classified as JASO MA. However, Rotella T with Triple Protection 15W-40 and our soon to be introduced Rotella T Synthetic 5W-40 CJ-4 do meet JASO MA."

Thank you for your interest in Shell products."
