CONVERSION INFORMATION Calculation: Examples:
128 ounces = 1 gallon
1 ounce = 0.0296 liters
16 ounces = 1 pint
1 gallon = 3.789 liters
1 gallon = 3.789 liters
# Liter x 1,000 (mL) / Ratio = mL of Oil to mix with Gas
# Gallons x 128(ozs) / Ratio = Ounces of Oil to mix with Gas
12 liter x 1,000 (mL) / Ratio50 (50:1 ratio) = 240 mL of Oil to mix with Gas
25 liter x 1,000 (mL) / Ratio50 (50:1 ratio) = 500 mL of Oil to mix with Gas
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

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.

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.
