DOMINATOR™ Synthetic 2-Cycle Racing Oil (TDR)

 DOMINATOR Synthetic 2-Cycle Racing Oil
Product Code: TDR • Brand: AMSOIL

Racers can't win what they don't finish. That's why AMSOIL formulators built DOMINATOR® 2-Stroke Racing Oil. This complex blend of oils and additives directly addresses the heat, pressure and friction of race-engineered engines. These engines operate on the edge, yet engine reliability is critical. DOMINATOR does an outstanding job protecting high-performance engines. It adds durability that professional racing teams depend on and delivers confidence so engines can be pushed to the limit.

Product Details

Product Applications

Use in high-performance stock or modified two-stroke engines, including air- or liquid-cooled snowmobiles, personal watercraft, motorcycles (moto X), ATVs, go-carts and outboard motors**. Good for use with coated or non-coated pistons, high-octane racing fuels and exhaust power valves. Compatible with most other two-stroke oils; however, mixing oils should be minimized.

Use in oil-injected and pre-mix applications that require API TC oils. In pre-mix applications, DOMINATOR delivers outstanding protection at 50:1 (2.6 oz. oil per U.S. gallon of gas), although many racers modify the mix ratio to suit their setup. Not suitable for use with alcohol or nitro-methane fuels.

** Not suitable for long-term use in outboard motors as a TC-W3-type oil, although excellent as a race oil for short-term use where motors are periodically inspected.

Product Description

DOMINATOR, an AMSOIL exclusive formulation, lubricates and protects high performance two-cycle motors, both on and off the track. High performance motors, particularly those that are modified, operate hotter and at higher RPMs than recreational motors, and they need good oil for peak performance. DOMINATOR is engineered for racing. It has the right film strength and clean burning properties for "on the edge" operation.

• Provides excellent film strength for high heat, high RPM motors
• Reduces friction for maximum power
• Recommended for use with coated or non-coated racing pistons
• Recommended for use with exhaust power valves
• Recommended for use with high octane racing gas
• Burns clean; Prevents ring sticking and plug fouling
• Provides excellent protection at 50:1 pre-mix or in injection system

Excellent Lubricity and Film Strength

High-performance and race-designed two-stroke engines operate under severe conditions. They are modified for higher compression ratios, higher rpm and leaner combustion, all of which increase heat and pressure. High heat can quickly burn off light oils and cause rapid piston expansion, decreasing piston-to-cylinder wall clearances and increasing the likelihood of piston scuffing and seizure. High pressure can exceed the film strength of low-viscosity oils, which promotes crankshaft bearing wear and pitting.

DOMINATOR is purpose-built for outstanding film strength and lubricity. It is engineered with carefully selected, higher-viscosity synthetic base oils to withstand the high heat and pressure common to high-performance and racing applications. DOMINATOR's anti-friction chemistry is race-proven to provide an extra measure of protection against piston scuffing and bearing wear.

Outstanding Cleanliness

The oil and fuel burned in the two-stroke combustion process leave destructive deposits on the pistons, rings and in the combustion chamber. Excessive deposits can lead to catastrophic engine problems, including ring sticking, exhaust port blocking and pre-ignition.

AMSOIL DOMINATOR is formulated with clean-burning synthetic base oils and powerful high-temperature detergent additives for exceptional deposit control. It helps prevent the power-robbing carbon deposits that cause ring sticking, exhaust port blocking and pre-ignition. AMSOIL DOMINATOR is optimized for severe service.

RACING IS RESEARCH™

During the opening weekend of the 2015/16 AMSOIL Championship Snocross season, professional rider Lincoln Lemieux's Ski-Doo* RS600 suffered a broken hose clamp, allowing the coolant to pump from the system. The intense heat that resulted melted the exhaust power valve covers, O-rings and engine gaskets. DOMINATOR Synthetic 2-Stroke Racing Oil, however, delivered exceptional protection despite the severe conditions. The rings and pistons were still free and the crankshaft turned freely. Scheuring Speed Sports is able to reuse the engine after repairing the melted parts, providing concrete testimony of DOMINATOR's superior performance.

HEALTH & SAFETY

This product is not expected to cause health concerns when used for the intended application and according to the recommendations in the Material Safety Data Sheet (MSDS).

Fantastic two cycle oil

I've been using this oil in my rx8 for a few years now and it is great for premixing with fuel and in the oil injection system. Rotaries need fresh two cycle oil and this stuff works

I have used other higher priced synthetics and this Dominator from Amsoil burns cleaner, gives great protection and costs less! Been running in cr500af for past couple months, will buy again.

Great Stuff

I have heard of Amsoil a long time. This is the first time I have used it. Seems like really good stuff without breaking the bank. I bought a 1 year membership and bought a bunch of supplies for the start of desert season.

THE best

I live in fl where it is hot in the summer. Oil breakdown is paramount on my harley's engine life! With the viscosity and proven quality of Amsoil 60 wt oil it has served me and my ultra classic bike like no other! Oil changes every 20k makes it well worth the couple $$ more for Amsoil than cheap competitor oils. Make it your own choice like i did for everything from weedeaters to my truck!

Great oil so far

I use the dominator pre mix oil in my 2015 Ktm 250 xcw. I mix it at 50:1 with 91 octane pump gas. Have had no problems with it and bike runs great at all temperature ranges. I race hare scrambles and enduros as a B rider so I am putting it through it's paces and it has performed great!

The Best Oil Yet

I have used several other racing oils and have had issues with all of them. Maxima Castor 927 came out of solution when the temperatures dropped. Klotz required regular remixing. I started using Dominator after my last piston change. That was 2 years ago. I haven't bought a piston since. It mixes easily. It stays in solution. The red color makes identifying the fuels easy, especially when the tags fall off the cans...
