Engine Oil

For optimum engine performance and maximum protection, use the following oil:
Application
All MerCruiser engines
IMPORTANT: Lubrication requirements for catalyzed engines differ from the requirements for noncatalyzed engines. Some
marine‑grade lubricants contain high levels of phosphorus, which can damage the catalyst system on MerCruiser engines.
Although these high‑phosphorus lubricants may allow acceptable engine performance, exposure over time will damage the
catalyst. Catalysts damaged by lubricants containing high levels of phosphorus may not be covered by the MerCruiser Limited
Warranty.
If Mercury MerCruiser Full‑Synthetic Engine Oil, 20W‑40 oil is unavailable, use the following lubricants, listed in order of
recommendation. If you are servicing a catalyst engine, use these for short periods of time only.
1. Mercury/Quicksilver 25W‑40 Synthetic Blend, NMMA FC‑W–rated 4‑cycle MerCruiser oil
2. Mercury/Quicksilver 25W‑40, NMMA FC‑W–rated 4‑cycle MerCruiser oil
3. Other recognized brands of NMMA FC‑W–rated 4‑cycle oils
4. A good‑grade, straight‑weight detergent automotive oil according to the last row of the operating chart below
