Oil/Gas Mixture Chart
For outboards that require a 50:1 premix of oil/gas we've put together the following chart to simplify the calculations.

Only use 2-stroke outboard motor oil with a 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.

The gas and oil mixture is 50:1 (25:1 during the initial break-in period).

Since trying to mix 1.28 ounces of oil for a half gallon of gas is a little difficult to measure, many people find it easier to purchase a 6 gallon fuel tank and mix 1 pint of oil (16 ounces) with the gasoline. Then use the 6 gallon tank to fill up your individual tank that you will be using on your boat.

During your initial break-in period you should use a 25:1 (double oil) mixture. See your owner's manual for complete details or view our Break-In Chart on-line.

 Conversion Information
128 ounces = 1 gallon
1 ounce = 0.0296 liters
16 ounces = 1 pint 1 gallon = 3.789 liters
2 pints = 1 quart
4 quarts = 1 gallon


Example of calculation:
GALLONS X 128 (ounces) / RATIO = OUNCES OF OIL TO MIX WITH GAS
6 gallons X 128 (ounces) / 50 (50:1 ratio) = 15.36 ounces of oil for 6 gallons of gas.
6 gallons X 8 (pints) / 50 (50:1 ratio) = 0.96 pints of oil for 6 gallons of gas.
