Sierra 10W-30 4-Stroke Marine Engine Oil, 30 Gallon Drum
Sierra 10W-30 4-Stroke Marine Engine Oil, 30 Gallon Drum — Product description
Sierra's SAE 10W-30 premium blend 4-stroke marine engine oil in a full 30 gallon drum. NMMA FC-W certified for outboards and inboards, built to fight saltwater corrosion and moisture. Sized for marinas, fleets, and busy service shops that go through oil by the case.
Sierra's SAE 10W-30 4-stroke marine engine oil is a premium blend built for the wet, hard-working life of a boat engine. This is the 30 gallon drum, so it's aimed at fleets, marinas, and busy service shops that go through oil by the case and don't want to keep cracking open quart bottles.
It carries the NMMA FC-W rating, which is the one that matters for four-stroke outboards and inboards. That means it's formulated to fight the corrosion and moisture that saltwater and layup season throw at an engine. It also meets the API SJ, CF-2, and CH-4 service categories, so it covers a wide spread of gas and diesel applications.
If you're running a single boat, a drum this size is overkill. But if you're changing oil across a dock full of engines, buying in bulk drops your per-quart cost and you're never caught short mid-season. Pump it, log it, done.

Frequently asked questions
Is this oil NMMA FC-W certified?
Yes. It carries the NMMA FC-W rating, the standard four-stroke marine spec for outboards and inboards, so it's formulated to handle the corrosion and moisture that come with life on the water.
How much oil is in the drum?
This is a full 30 gallon drum, sold as a single. It's meant for high-volume use like marinas, fleets, and service shops rather than a one-off oil change.
Can I use this in both gas and diesel engines?
It meets API SJ for gas engines plus CF-2 and CH-4 diesel service categories, so it covers a wide range of four-stroke marine applications. Always check your engine maker's recommended viscosity first.
What viscosity is this oil?
SAE 10W-30, a common all-around grade for four-stroke marine engines. Confirm it matches what your engine manufacturer calls for before you fill.
