Engine Compatibility
The strongest supportable fitment for 8M0149213 is Mercury 3.4L V6 and 4.6L V8 outboards, plus other four-stroke outboards up to 150 HP where 10W-30 is specified. That is the clearest current OEM guidance tied to this oil family.
Serial Number Fitment Notice
Match this product by the engine oil specification in the owner’s manual or service manual rather than by serial number alone. The key check is whether the engine calls for 10W-30 4-stroke marine oil, because this is a lubricant selection decision rather than a hardware fitment part.
When This Part Needs Replacement
Replace or refill with this oil as part of normal scheduled engine-oil service for compatible 4-stroke marine engines. In practical service terms, this oil is used when performing routine oil changes or seasonal maintenance on engines that specify 10W-30 marine oil. That guidance follows Mercury’s description of the oil as a 4-stroke marine-engine lubricant for those applications.
Installation Notes
Use 8M0149213 only in engines that call for SAE 10W-30 4-stroke marine engine oil. Check the owner’s manual or service manual before use, and confirm the correct viscosity and oil type for the engine family being serviced.
Alternate/Superseded Part Numbers
Current sources reviewed identify 8M0149213 as the Mercury 1-gallon SKU for this 10W-30 synthetic blend oil package. Related Mercury and Quicksilver 10W-30 synthetic blend oil listings exist in other package formats, but the exact SKU requested is the 1-gallon Mercury-branded version.
Parts Desk Insight
With engine oils, the most important match is the viscosity and engine family requirement, not just the brand name on the bottle. For 8M0149213, checking that the engine specifically calls for 10W-30 4-stroke marine oil is the best way to avoid ordering the wrong lubricant for the service.
