GAS / OIL MIXTURE CALCULATOR

To calculate mixtures for other amounts of gas, use our handy calculator below.

Liter 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
1 gallon = 3.789 liters
Calculation:
# 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
Examples:
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.

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.
