Engine Compatibility

The strongest supportable fitment for 8M0230196 is Mercury OptiMax and other direct fuel injected (DFI) 2-stroke outboards. Mercury’s current DFI oil guidance recommends this oil type for Mercury OptiMax 2-stroke outboards and other DFI 2-cycle engines, and the current dealer listing for this exact SKU describes it the same way.

Serial Number Fitment Notice

Match this product by engine oil specification and engine family rather than by serial number alone. The key check is whether the engine is a Mercury / Mariner direct fuel injected 2-stroke outboard that calls for Optimax / DFI oil, because this is a lubricant application decision rather than a hardware fitment part.

When This Part Needs Replacement

Replace or refill with this oil as part of normal oil-tank replenishment for compatible DFI 2-stroke outboards. In practical service terms, this oil is used when the engine’s oil reservoir needs topping up or refilling with the correct DFI-grade lubricant to maintain proper protection and performance. That guidance follows Mercury’s description of this oil as the correct lubricant for OptiMax and DFI engines.

Installation Notes

Use 8M0230196 only in compatible DFI 2-stroke outboard oiling systems. Current dealer guidance for this exact SKU also notes that it is intended for direct-injection 2-stroke engines and not for mixing with gasoline.

Alternate/Superseded Part Numbers

Current SDS and cross-reference sources associate this oil family with related Mercury numbers including 8M0229798, 8M0229800, 8M0229796, and 8M0230194. Current dealer and retail sources also tie the same DFI oil formula to 858037K01 / 92-858037K01 one-gallon packaging.

Parts Desk Insight

With oil listings like this, the most important check is the engine oil type and package size, not just the words in the product name. For 8M0230196, current sources consistently line up around Mercury Optimax / DFI synthetic-blend 2-stroke oil in a 10L package, so confirming the engine’s DFI oil requirement first is the best way to avoid ordering the wrong lubricant format.
