Hey Guys, I'm about to do my 10 hour service on my Mav. Of course the book recommends the XPS brand, But then goes on to say if XPS is not available to use a four stroke 5W 40 with at least one API rating of Either SJ, SL, or SM. On another thread a guy recommended Shell Rotella T6 Full Synthetic. When I got down to the auto parts store The Rotella T6 was for Diesel Engines, That put a lot of doubt in my mind, so that was out. All the motorcycle oils were 10W 40. And most of the car oils were 10W 40. The only oil I could find With 5W 40 was Castro Edge Full Synthetic. It had an API rating of SL and SM, so I decided to go with the Castro. Here are my concerns, In the manual it say to use 4 stroke oil, not specifically motorcycle oil. . . .Last time I checked cars are four stroke engines. . . .Is there really a difference between 4 stroke motorcycle oil and car oil ?? Would you guys run the common 10W 40 motorcycle oil instead of the weight recommended 5W 40 car oil ?? What's your opinion of that Castro full synthetic 5W 40 ?? Finally. . . .What are you guys running ???
THANKS for all your input, and hopefully this could help other guys out. . . ..
