Read your Operators Guide and you will see that you MUST use only API TC Low Ash Oil. You do not need to use Sea Doo's brand which is quite expensive when compared to other brands.
Now, depending on the engine in your Doo, i.e., 587-687, you can use Quicksilver PWC (synthetic blend)(silver container) which is best for a 587-687 because is contains 70% mineral oil.
If you have a newer Doo, 787 and above, you need full synthetic, which Quicksilver also manufactures in a black container.
Do not use Quicksilver Premium even though it is API TC because it is Ashless and your rotary needs the ash.
Don't mix oil brands.
