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

DOMINATOR® is recommended for use in high-performance stock or modified two-cycle engines, including air- or liquidcooled 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 where API TC oils are specified. 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. See teardown photos below.

Outstanding Cleanliness

The oil and fuel burned in the two-cycle 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™

AMSOIL disassembled the Rotax® motor from Scheuring Speed Sports' Ski-Doo® race snowmobile ridden by Robbie Malinoski during the 2010/2011 professional snocross tour. Both pistons revealed minimal wear and were suitable for continued use. AMSOIL DOMINATOR delivered outstanding protection for Malinoski's Ski-Doo in the most severe environment.

Great Product

Used in a 2017 YZ125 ..... piston wasn't changed until after 30+ hours and it looked like new. Something must be working, I'm guessing the DOMINATOR 2 stroke oil

Dominator 2 stroke oil

Great 2 stroke oil. Burns clean and keeps my bike running strong. Going on 105 hours on the motor with no issues. Run it in everything 2 stroke I own

Great product

Have tried other oils and had loading issues along with fouling plugs. I switched to the Dominator 1.5 years ago and have not fouled a plug since.

Happy customer

We as a family use this in all our 2 stroke toys. My boys race a KTM 50 pro senior & a YZ 85. They run great on this & it's honestly our favorite that we've tried in them. The only thing is the KTM does smoke & we do mix it to the ratio called for.

I ride a high strung, 40+ year old 2 stroke street bike and Dominator 2 stroke oil fits the bill perfectly

Great product will buy again

I use Dominator 2 stroke oil in my dirt bike because that's what the previous owner used at it works great. I've hade no issues and have kept used because of that!

Will buy again

This oil is the best that we have found to use in our 2013 KX 100. While doing our tear down on the bike, there were no scuff marks on the piston, like we have seen with other cheap oils. Would recommend this product to anyone looking to improve the quality of your 2 strokes.

Excellent Product

I am a landscape contractor and run a lot of 2 cycle equipment. I switched to this oil because it costs less than half that of name brand synthetic mixes and it works just as good if not better. I buy it by the gallon which is more practical than the single use bottles. No smoking or fouling of any kind
