PWC oil vs TC-W3?

[Tiller guy]

If I run my outboard WOT 90% of the time would the Quicksilver Full Synthetic 2-Stroke PWC Oil be safe? Someone gave me 2 gallons of it for free.

I've tried it before, and didn't see or detect any negative effects. But I mostly use my Pennzoil outboard oil though.

PWC engines are very high performance compared to typical outboard engines. PWCs can make 1-3/4 to 2++ HP per cubic inch, and are comparable or surpass racing outboards in that respect. So, the oil they use is probably formulated for high stress and heavy load situations. It might not be a bad choice! Maybe someone on here knows something in detail about it.

I was reading that some of the high performance oils will cause plug fouling in low temp motors. My motor almost runs too clean now if that's even possible?
