Shell Rotella Oil??

I emailed Shell to get confirmation if the Heavy Duty Diesel Engine was suitable for dirt bikes, and here what I received:

"Yes, Shell Rotella T Triple Protection Oil SAE 15W-40 would be an excellent choice for your application. While the product is primarily marketed for diesel engine applications, it does also meet the requirements of API SM for use in 4-stroke gasoline engines. More importantly for your equipment, it also meets the requirements of JASO MA and MA2 for use in wet clutch-equipped bikes."

Just a heads up, in case some are in doubt. As stated before the local Walmart only carries the Heavy Duty Diesel Engine Oil.
