Ok so Ive been thinking about this a lot. You dont typically see 5qt jugs of motorcycle oil, ever. So cost saving bulk is not going to be an option. Synthetic MC oil is very expensive at $10+ a quart. With Rotella being JASO-MA certified how in the F would anyone not want to use this oil over anything? You can get it in 5qt jugs at a decent price at Walmart and its been more than proven to run well in a motorcycle and is all over the internet how well this oil runs in motorcycles. Other than brand preference is there much of a reason to use any other motorcycle oil over Rotella if your seeking JASO-MA certified oils?
