Mercury formulated 8M0230196 specifically for direct fuel injection (DFI) 2-stroke engines operating at reduced oiling rates and higher combustion temperatures. Always confirm the correct oil specification in your engine owner’s manual before use.

Package Size Note
Canadian listings identify 8M0230196 as a 10 L package. Some North American catalogs describe the same SKU as 2.5 US gal / approximately 9.46 L. This reflects market labeling differences only — the oil formulation is identical.

Parts Desk Insights
The 10L container is the right choice for OptiMax owners who go through oil regularly, or for shops and marinas doing DFI oil services on multiple boats. The cost-per-litre advantage over the 4L bottle adds up quickly if you’re running a high-hour OptiMax season. The key thing to nail before ordering: confirm your engine’s reservoir calls for “OptiMax Oil” or “DFI Oil” — if it does, this is your product. If the reservoir or manual says Premium or TC-W3, that’s a different oil. Running standard TC-W3 in a DFI system can cause carbon buildup in the injection components over time, which is one of the more avoidable service headaches we see on these engines.
