AMSOIL Lubricant – DOMINATOR Synthetic 2-Stroke Racing Oil (TDR)
AMSOIL oils and additives – lubrication is the last place to compromise.
Amsoil is a US-based lubricant manufacturer known for maintaining extremely high quality standards without the cost-cutting measures that have affected many traditional oil brands. The focus is purely on lubrication performance and engine durability.
In our own workshop projects Amsoil is often a requirement, not just a recommendation. A quality oil is the cheapest insurance you can buy for a tuned or heavily loaded engine.

What should you know about this product?
DOMINATOR 2-Stroke Racing Oil is a 2-stroke oil engineered for minimal friction and maximum film strength in high-RPM, high-heat racing engines. It is optimized for severe service.
The oil burns exceptionally clean and is formulated with powerful high-temperature detergent additives to prevent carbon deposits, ring sticking, and exhaust port blocking. Its anti-friction chemistry is race-proven to provide an extra measure of protection against piston scuffing and bearing wear.
It can be used in oil injection systems or pre-mixed at a 50:1 ratio (2.6 oz. oil per U.S. gallon of gas), though many racers modify the mix ratio to suit their setup.
Important Notes: Not suitable for long-term use in outboard motors where a TC-W3 oil is required. Not recommended for use with alcohol or nitro-methane fuels.
