So I bought my boat 10 days ago and need to add oil. He used sythetic Sea Doo oil, And I can only find synthetic Quick silver PWC.

CAN I MISS THESE??????????????

[JWLogsdon]

grey bottle for $24. or black bottom for $37. black is full synthetic. grey has synthetics added....which one is everyone using.

I asked this same question in another thread and got the do not mix response . If I am using the BRP full synthetic xps and switch to the quicksilver pwc full synthetic why can it not be mixed, they are both synthetic? if there is a good reason with facts behind it can someone please let me know.

i'd run the oil resivoir low, then top off with new stuff.
