When to Use / Replace?

Use in outboard or sterndrive engines for everyday boating or harsh marine environments. Replace every season or up to 16,000 km (about 10,000 miles) of operation, following your engine manufacturer's guidelines—whichever comes first. Check levels monthly and change sooner if boating in saltwater or after extended idling.

Pro Tip: Mixable with synthetic or mineral oils for top-offs.
