Quicksilver DFI 2-Stroke Marine Engine Oil – 208L Drum
Engineered specifically for direct injection 2-stroke outboard engines, this full-drum supply of Quicksilver DFI oil keeps high-performance marine powerplants running clean and protected through demanding on-water use. The 208-litre drum format is the right choice for marinas, commercial operators, and high-volume boating operations that go through oil regularly and want to reduce per-litre cost.
What It's Designed For
- Mercury and Mariner OptiMax direct fuel injection (DFI) outboards
- Any Mercury or Mariner 2-stroke DFI engine requiring a dedicated DFI-rated oil
- High-cycle commercial and charter applications where bulk supply makes operational sense
Why DFI Oil Is Different
Direct injection engines run leaner fuel-to-oil ratios and at higher combustion temperatures than carbureted 2-strokes. Standard TC-W3 oils are not formulated for these conditions. This oil is purpose-built to handle the heat, reduce carbon deposits on injectors and power valves, and maintain consistent lubrication across the RPM range — protecting your investment in a high-output powerhead.
Key Characteristics
- Formulated exclusively for DFI and OptiMax 2-stroke outboard engines
- Helps minimize injector fouling and power valve sticking
- Supports clean combustion and reduced exhaust smoke
- 208L drum — ideal for bulk dispensing at a marina or service facility
- Part number: 8M0229803
Parts Desk Insights
Best use case: This drum format is the go-to for marina fuel docks, outboard service shops, and commercial fishing or charter fleets running multiple OptiMax or DFI-equipped engines. If you're servicing a single recreational boat, consider a smaller container size. For a related DFI oil option, see the Mercury 2-Cycle DFI Oil 8M0230194. If your engine calls for a TC-W3 rated oil instead of a DFI-specific formula, the Mercury Premium TC-W3 2-Stroke Oil 858021KC1 is the appropriate alternative.
Compatibility note: Always verify your engine's oil specification in the owner's manual before ordering. OptiMax and DFI engines require this dedicated oil — substituting a standard TC-W3 oil can void warranty coverage and cause long-term injector and power valve damage.
