What octane do you guys run?
I'm relatively new to the PWC world, but I've been riding off-road motorcycles and ATVs for the bulk of my life. I've always ran BP 93 octane in my two strokes, but I was recently told that my jet ski doesn't need premium. What octane fuel do you guys run?

87. More octane doesn't improve performance unless the compression is increased or the engine is boosted. Too high an octane can actually hurt performance.

I have to wonder how old that article is, as it talks about the new TC-W3 oils. I've never seen any significant coking of the piston skirt, and I think most carbon deposits are the result of oil, not gasoline. The article also seems to imply that the pistons contact the cylinder walls to dissipate heat--I don't think so.
While I think the ethanol that is put in gasoline is a major problem, I really don't think 87 octane gasoline is a problem.
