Re: Amsoil??
Goto to their product info page both of their 2-stroke oils are reccomended for air and water cooled engines. Their both reccomended for tc-w3 use. This is both of their 2-stroke oils Here's what they say:<br /><br />100:1 PRE MIX<br /><br />APPLICATION RECOMMENDATIONS - ATC 100:1 PRE-MIX<br />AMSOIL Synthetic 100:1 Pre-Mix 2-Cycle Oil (ATC) is recommended for all water-cooled and air-cooled pre-mix applications. A mix ration of 100:1 is recommended for normal duty service in applications such as motorcycles, outboard motors, snowmobiles, weed eaters, lawn mowers and chain saws. For "severe service" applications, richer mix ratios of 50:1 to 80:1 are recommended. These include racing motors and hot operating workhorse motors that continuously run for extended periods of time.<br /><br />AMSOIL Synthetic 100:1 Pre-Mix 2-Cycle Oil is recommended for all pre-mix applications specifying TC-W3, API TC, JASO FC and ISO EGD. It is recommended for use with gasoline fuels only, and is not recommended for oil injection systems.<br /><br />Outstanding Low Temperature Performance<br /><br />Both AMSOIL Synthetic Injector Oil and 100:1 Pre-mix Oil mix readily with fuel even in low temperatures. However, AMSOIL Injector Oil with its -45°F pour point and SAE #4 miscibility and fluidity rating, is better suited for severe cold. It is recommended for use in injector systems as well as 50:1 pre-mix. Also, AMSOIL injector oil will help ease starting because it does not solidify or get gummy in the motor which allows it to turn over more freely.<br /><br />SERIES 2000<br /><br />Applications<br />AMSOIL Series 2000 2-Cycle Racing Oil is recommended in air or water-cooled two-cycle motors where NMMA TC-W3, API TC, or JASO FC oils are specified. It is excellent for both racing and recreational use in snowmobiles, outboard motors, personal watercraft, motorcycles and ATVs. AMSOIL Series 2000 2-Cycle Racing Oil is not recommended for use in aircraft or for use with nitromethane or alcohol fuels.<br /><br />Recommended for use at a 50:1 mix ratio or as an injector oil for both racing and recreational use. Also recommended for use in all oil injection systems. Recommended for use with catalytic converters.<br /><br />Keeps Engines Clean<br />AMSOIL Series 2000 2-Cycle Racing Oil contains additives that have been tested and proven to provide superior cleanliness in both air and water-cooled motors. AMSOIL Series 2000 2-Cycle additives inhibit the formation of deposits in the ring grooves, in the combustion chamber and on the exhaust power valves. With AMSOIL Series 2000 2-Cycle Racing Oil rings do not stick and spark plugs do not foul from carbon deposits, and exhaust power valve maintenance is minimized.<br /><br />Compatibility<br />AMSOIL TCR is compatible with TC-W3 lubricants and most other two-cycle oils. For best performance, cross contamination should be minimized<br /><br />For more info goto their web site or call them.
