Nissan Marine Outboards - Authorized Distributor Offering Boat Motor Products, Technical Information, & Dealer Locations for the U.S. & Canada."

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!

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.

Oil & Gas Mixture Chart
For 2-Stroke outboards that require a 50:1 premix of oil/gas we've put together the following chart to simplify the calculations.

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:

Nissan Marine Complete Advantage 100% Synthetic Oil
Nissan Marine Premium TCW3 Semi-Synthetic Oil
Tohatsu Complete Advantage 100% Synthetic Oil
Tohatsu Premium TCW3 Semi-Synthetic Oil
Pennzoil 100% Marine Synthetic
Pennzoil Semi-Synthetic Outboard Oil
Mercury Optimax/DFI Oil
Yamaha Yamalube 2-M Semi-Synthetic Injector Oil
Bombardier XD-50 Semi-Synthetic Oil
Bombardier XD-100 Full-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.

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
