With the exception of our outboards which have oil injection systems, Nissan 2-stroke outboards require a 50:1 (2.5 ounces of oil for each gallon of gas) oil/gas mixture after the initial break-in period. Nissan outboards which have oil injection will automatically mix the correct amount of oil and gas depending on the engine requirements; you don't have to pre-mix your oil & gas with these systems. We've put together a handy chart to help you calculate the amount of oil/gas to mix.

With the exception of our outboards which have oil injection systems, Tohatsu 2-stroke outboards require a 50:1 (2.5 ounces of oil for each gallon of gas) oil/gas mixture after the initial break-in period. Tohatsu outboards which have oil injection will automatically mix the correct amount of oil and gas depending on the engine requirements; you don't have to pre-mix your oil & gas with these systems.

For your 2-stroke outboard, be sure and use only 2-cycle outboard oil, with an NMMA (National Marine Manufacturers Association) certified rating of TCW3. Never, never, never use automobile oil in your 2-stroke outboard. You can find Nissan 2-stroke outboard motor oil at your local dealer.

No, all Swisher Trimmer/Mowers are 4 cycle engines that have a separate oil fill. No mixing is required.

Since these engines have no sump to hold oil for engine lubrication, like nitro, the oil comes from the fuel. You need to mix your pump gas with a specific amount of 2-stroke oil, in order to provide the engine with the lubrication (and cooling) that it needs. What oil? Well, there are many topics about this, but the key here is to get a good performance 2-stroke oil.

For your 2-stroke outboard, be sure and use only 2-cycle outboard oil, with an NMMA (National Marine Manufacturers Association) certified rating of TCW3. Never, never, never use automobile oil in your 2-stroke outboard. You can find Tohatsu 2-stroke outboard motor oil at your local dealer. 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 mixture should be 50:1 using a good quality petroleum-based oil such as that offered by Husqvarna. Never use synthetic oils in the fuel/oil mixture.

There are many different mix ratios, the gas oil mix should be indicated on the fuel cap of your machine, or in the owners manual. Use the chart below as a guideline only:

For the 2-stroke models, any 5/32" x 1" (4mm x 24mm) shear pin will work just fine. There are two types of shear pins available; brass and stainless steel. Brass shear pins will "give" if you strike an underwater object, however, brass shears pins may also break more easily if shifting or accelerating too quickly. Stainless steel shear pins are much harder than brass shear pins and won't give if striking an object and may cause damage to the prop.

Most motorcycle tuners will suggest a 32-1 mixture. This does depend on the type of oil you use, assuming that you are using quality oil, generally a synthetic or semi-synthetic lubricant. Keep in mind changing mixtures can vary the jetting, so find what works and stick with it.

The standard engine mixing ratio for Gas and Oil is 50 to 1, however some brands of pocket bikes using off brand engines may need a mixing ratio for Gas to Oil at 25 to 1. Be sure to read your owners manual before fueling your pocket bike. A new engine should have a richer mixture of 40 to 1 for the first tank of fuel to help with proper break in. Do not use a mixture of less than 40 to 1 as it will be too rich and may foul the spark plug.
