Your 1994 Mercury 200HP Black Max uses Premium Plus (Recommended) or Premium Synthetic Blend. **Q: Is this a tcw3 oil? Is it better than quicksilver premium plus? Can I use it in my 2003 135 optimax?** A: It is not a TCW3 oil, it was formulated for hpdi (high pressure direct injection) engines, specificly Optimax. I use this oil exclusively in my 2002 optimax 135. I run only alcohol free gas and I add Mercury Quickare Fuel Treatment to every tank. **Q: Can i run this oil in my 1996/1997 mercury black max 150 hp efi** A: This oil is not recommended for EFI or carb motors. Use Premium Plus or Premium for your 1996/97 Black Max. **Q: How long does a gallon last in a 115 hp ?** A: depends on how much you use your boat. I fish about 4 to 6 times a month. a gallon would probably last me about 3 months. In my opinion, its the best oil for a Mercury. I have a Mercury 225 opti max ## Frequently Bought Together - Mercury Marine 92-858037K01 OptiMax/DFI 2-Cycle Outboard Oil - Mercury Quickleen Engine & Fuel System Cleaner - Quicksilver 858064Q01 High Performance SAE 90 Gear Lube for Mercury Outboards and MerCruiser Sterndrives, 32 oz --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/1626665-mercury-optimax-dfi-2-cycle-outboard-oil-1-gallon-92](https://www.desertcart.sn/products/1626665-mercury-optimax-dfi-2-cycle-outboard-oil-1-gallon-92) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-06-20*
