Engine Oil Recommendations
We recommend the use of Mercury or Quicksilver SAE 10W‑30

MerCruiser 4‑cycle engine oil or Quicksilver sterndrive & inboard
4‑cycle engine oil. Never use 4‑cycle engine oil that is not certified
to meet or exceed any one or combination of the following
American Petroleum Institute (API) Service Classification SH, SG,
SF, CF‑4, CE, CD, CDII. Severe engine damage may result from
use of an inferior oil.
