brands of oil??

[Doug H.]

WHAT WEIGHT OF OIL DO YOU GUYS RUN IN YOUR JET BOAT AND WHY? SYNTHETIC? OR BLEND? 10-30 OR STRAIGHT 30?

[MAXIMUS]

I use Torco straight 50 weight.

[Squirtcha?]

Valvoline 20W50 full synthetic.

[GlastronGuy]

I had been running Torco 20W50. The last time I bought oil, no one had it. I bought Valvoline VR1 Racing, 20W50. It actually seemed to hold up a little better than the Torco.
I also run Pro Blend additive.
