For 2-Stroke outboards that require a 50:1 premix of oil/gas we've put together the following chart to simplify the calculations. Use ONLY 2-stroke outboard motor oil with an NMMA (National Marine Manufacturer's Assoc.) certified rating of TCW3. Never use automobile motor oil in your 2-stroke outboard! TLDI outboards should only be run using TCW3 oil specifically formulated for use in Direct Injection motors. Standard TCW3 oil is not recommended for use in TLDI outboards. The following oils have been tested by our factory and certified for use in TLDI motors: Tohatsu Marine Premium Oil Nissan Marine Premium Oil Pennzoil Complete Marine Synthetic Pennzoil Semi-Synthetic Outboard Oil Mercury Optimax/DFI Oil Yamaha Yamalube 2-M Semi-Synthetic Injector Oil Bombardier RAM Ficht Oil The above oil brands are currently the only brands that have been tested and approved by our factory for use in TLDI systems. Brand names listed are trademarked by their respective owners.Unleaded gasoline with a minimum octane rating of 87 is necessary; however, we recommend using an octane rating of 89, if possible, for best performance.
