I have run about 40 to 50 gals. of gas with pennzoil tcw3 blend not knowing it required api-tc. Bought seadoo use and am fairly sure previous owner used a BRP oil but do not know which.
Question, can i siphon the majority out of the oil tank reservior and add what you would reccomend?
Question, do i need to drain the lines,oil tank, rotary chamber,injection pump and bleed?
Question, what BRP oil would you reccomend?
BRP Mineral / Blend / Full Synthetic
Some have said to run mineral others say blend.
Gets confusing. Have had no problems with 717.
Changed fuel lines and filters.
How do you vacum tank and lines with shop vac.

Any info would be appreciated. The more detail the better. Thanks for your time and info.
Thanks again, Ronnie from north carolina

api tc is always recommended but not always required.

i personalty use tcw3 because im cheap and my 657 overheats at 205 degrees (well below the temperature tcw3 starts to break down at).

Run the mineral BRP oil, that is what is factory recommended for this motor. Get to Walmart and buy a $7 hand pump and siphon out the existing oil from the tank and fill up with the good BRP mineral and you'll be good to go. No need to get too crazy and clear out the oil lines because you might introduce air into them and seize you engine.
