Dominator is designed for 2-stroke racing engines only. It is made for very hot operating temps and engines that are pushed to sky-high RPM.
A daily-use trail or mountain sled simply will not run hot enough to completely burn off Dominator’s additive package. What if your engine is modified or even turbo-charged? AMSOIL Interceptor is the more appropriate choice for all recreational use. This is the case regardless of how fast you ride.
Another major consideration is that Dominator’s detergent content is relatively low. The reason for this is that racing engines torn down frequently and run ultra-hot. So there is little need for a significant amount of detergent in the formula. When used in recreational engines, Dominator could contribute to some deposit build-up. Interceptor has a very robust detergent package. For this reason alone, Interceptor is a far better choice that Dominator in high-performance snowmobiles with variable exhaust power valves.
Does Interceptor Offer Less Wear Protection Than Dominator?
In terms of protection and performance, Interceptor is not a step down from Dominator. Dominator has a slightly thicker viscosity than Interceptor. But Interceptor also withstands extreme heat and heavy loads, while keeping power valves clean over extended periods. Interceptor is not a compromise for recreational-use. It provides the perfect balance of performance, top-notch protection and clean operation.
Getting The Correct Oil For The Job
We recently had a call from a customer that owned two Ski-Doo snowmobiles. One with the latest 800cc E-TEC engine and a 550cc fan-cooled engine in the other. He assumed that Dominator Racing Oil was AMSOIL’s best two-stroke oil. Therefore, he believed that he was doing right by his engines by using Dominator.
As a result of our conversation, he chose Interceptor for both machines. He could have used AMSOIL Synthetic Injector Oil in the 550cc fan-cooled engine. But he went with Interceptor in order to keep one oil on hand.
Here are AMSOIL’s three snowmobile 2-stroke injectors oils and a brief description of their intended use.
AMSOIL Interceptor– the premium choice for the very latest high-performance engines. Especially ideal for engines with power valves. A terrific upgrade over OEM synthetic injector oils. Interceptor is one of AMSOIL’s most acclaimed products
AMSOIL Synthetic Injector Oil– A value-priced synthetic 2-stroke oil. Ideal for utility machines, fan-cooled models or older high-performance engines. Suitable for use with power valves.
AMSOIL Dominator 2-Stroke Racing Oil– For racing engines only. Provides industry-leading protection and performance under extreme loads.
