99/GTS 720 Rotax Oil type

[gray]

Just got a Seadoo gts with a Rotax 720 engine. I know the oil wars and
can seem to find anyone that really has a straight answer yes or no on say
QuickSilver oil in a 720 Rotax. At walmart they had the following.

1.)"QuickSilver Premium" at 21.00 for TW3 rated I know this will not work.
2.)"QuickSilver PWC 2 cycle" at 23.00 per gal. that says its a API-TC for Seadoo, Yamaha Etc. Will this work Yes!!! or No!!!! in a Rotax 720 engine
3.)"QuickSilver Synth" at 28.00 per gal. Question I thought I see on a seadoo
post that the Rotax needed some Ash content to the oil. Or are the Synth oils so good that ash content is not a issue.

thanks allot for your time and help on this oil question, gray

I always use the Seadoo brand XP-S synthetic. Here is the recommendation from seadoo, any other oil you use must meet these requirements.

Never use 4-stroke petroleum
or synthetic motor oil and never
mix these with outboard motor
oil. Do not use NMMA TC-W, TC-W2
or TC-W3 outboard motor oils or
other ashless type 2-stroke oil. Avoid
mixing different brands of API TC oil
as resulting chemical reaction may
cause severe engine damage.

Im not hung on Quicksilver could be Pennzoil oil API-TC for Rotax 720 engine.
But they are OK to Use as long as they are not mixed with others or for the 720 Rotax is the full say Quicksilver Synth better or not needed vs. API-TC
oil????
thanks gray
