i was turned onto royal purple 10 w 40, seemed to do the job no complaints, any thoughts?
True. I am a firm believer in motorcycle specific oils. Of coarse people with disagree but the problem with car oils is the lack of Zinc/Phos (now days it is really bad)and they do not have good shear resistance additive. The trans and engine sharing oil is very hard on oil. Will car oils work? Of coarse they will. It is not the best oil you can use in your bike though. Saving 20 to 30 bucks on a oil change when you have thousands in your bike does not seem like money well spent to me. Never has.about the rotella.....I have been using for years with no issues. However, rumor has it that the formula has changed. This was recently posted on another forum I visit.
Shell Rotella Motor Oils (A diesel oil commonly used in sportbikes) are now API-SM rated (Versus the SG Rating it previously held).
What Does This Mean?
-Lower Concentrations of ZDDP
-Lower Concentrations of Phosphate
-Addition of Wear Additives & Friction Modifiers
*Friction Modifiers cause wet clutch slippage
In Laymans Terms.
-Anyone whose bike has a Wet Clutch should consider discontinuing their usage of Shell Rotella Motor Oil (Its safe to use their SG Rated oil if you still have some).
What Should I Use Instead?
1. Use what's recommended by your motorcycles manafacture at a minimum if you are unsure of what to use.
2. For further recommendations & explanation read the next section.
Can anyone confirm or deny this? I actually have a gallon sitting in my basement right now, but I keep forgetting to look at it to see if it's true or not. If so, and it's no good for bikes anymore, they're going to be missing alot of business next quarter.
