Quicksilver Synthetic 20W-40 Sterndrive/Inboard 4-Cycle Oil
Quicksilver Full Synthetic 20W-40 Sterndrive & Inboard 4-Cycle Oil
Quicksilver Synthetic 20W-40 4-Cycle Oil is for use in sterndrive and inboard engines. 20W-40 can be used on any sterndrive/inboard engine equipped with or without a catalytic converter.

This oil contains low levels of phosphorous, reducing potential damage to the catalyst. Quicksilver 20W-40 keeps dirt and debris from settling on metal surfaces and provides exceptional rust protection.
