Genuine Tohatsu Engine Oil is specially formulated to work with all Tohatsu engines: 2-strokes, TLDI, and 4-strokes. Tohatsu Genuine Oils contain additional additives and detergents to keep your Tohatsu outboard running at peak performance.

 

Oil & Gas Mixture Charts


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 Complete Advantage 100% Synthetic Oil

  • Tohatsu Premium TCW3 Semi-Synthetic Oil

  • Nissan Marine Complete Advantage 100% Synthetic Oil

  • Nissan Marine Premium TCW3 Semi-Synthetic 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.

Gallons of Gas Oil Measurement Mixture Ratio Answer
 

 

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

 

Calculation:

# Gallons x 128 (ozs)  / Ratio = Ounces of Oil to mix with Gas

Examples:

6 (gallons) x 128 (ozs) / 50 (50:1 ratio) = 15.36 ozs 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
