About AMSOIL Interceptor
Interceptor is AMSOIL’s premiere two-stroke snowmobile injector oil. It is a direct replacement for Ski-Doo XPS 2T E-TEC Synthetic Oil, Polaris VES Full-Synthetic 2-Stroke Oil and Arctic Cat C-TEC2 Synthetic 2-Stroke Oil. Interceptor is widely known for its ability to keep variable exhaust power valves clean. It provides exceptional wear protection and optimal throttle response. As a result, Interceptor is one of AMSOIL’s most popular products (and for good reason).

AMSOIL Dominator Synthetic 2-Stroke Racing Oil could be considered the best product in its category on the planet. But we spend far more time talking customers OUT of buying Dominator for snowmobiles than selling it. Let us explain.
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.
Below is a list of the 2020 Polaris snowmobile line-up along with an AMSOIL Synthetic Oil suggestion for each model and engine option.
There are a few new Polaris models for the 2020 season. The highlight is a new specialized mountain sled called the RMK KHAOS. They have also introduced an economical 550cc mountain machine called RMK EVO. Touring enthusiasts might be interested in the 600 INDY Adventure. Polaris also created a high-octane, do-it-all sled in the INDY 850 XC 137.

Here are our oil recommendations for the 2020 Ski-Doo snowmobile line-up.
Ski-Doo’s product line sees modest changes for 2020. However, one of the big highlights is the revamping of Expedition line of touring/utility sleds. These models now ride on Ski-Doo’s top-shelf REV Gen4 chassis. Another interesting addition is the optional “Expert” package for the Summit X mountain sled. The Expert package is tailored for serious back-country powder carving.
There is an interesting Ski-Doo-related update regarding AMSOIL products. Ski-Doo now dictates that injector oils must meet the JASO FD oil standard for their E-TEC 2-stroke engines. AMSOIL Interceptor meets and exceeds the JASO FD specification. Therefore, the JASO FD spec has now been added to the Interceptor label.
Below is a list of the entire 2020 Ski-Doo snowmobile line along with the correct AMSOIL synthetic oil recommendation for each model and engine option.
AMSOIL Synthetic Products For 2020 Ski-Doo Snowmobile Models
AMSOIL Interceptor Synthetic 2-Stroke Oil For E-TEC Engines
Interceptor delivers all of the performance and protection offered by BRP 2T E-TEC Full-Synthetic Oil. However, Interceptor is available at a lower price (request a price list with the form on this page). Interceptor has been fully and thoroughly tested in E-TEC engines. Our customers have logged hundreds of thousands of real-world miles with Interceptor in E-TEC motors. The clean RAVE valves, exceptional performance and world-class protection leaves no doubt. AMSOIL Interceptor is the ultimate E-TEC injector oil.
AMSOIL Synthetic 2-Stroke Injector Oil
Why not replace XPS 2T Carb Premium Mineral Oil with full-synthetic injector oil at a lower price? AMSOIL Synthetic Injector Oil is perfect for any recreational or work snowmobile. It is even suitable for older Ski-Doo models with RAVE valves. Interceptor is our dedicated E-TEC oil, but this product can be used in any other Ski-Doo 2-stroke engine. AMSOIL Injector Oil delivers clean operation, outstanding performance and great wear protection at a value price. It can also be used as a premix.
AMSOIL Formula 4-Stroke 0W-40 Synthetic Oil

A reader asks:I’ve got a 2015 Ski-Doo Summit X 800R with a BoonDocker turbo kit. BoonDocker suggests their T2C 2-Stroke Injector Oil. I’d like to go with an AMSOIL option. Would Dominator racing oil or Interceptor be suitable for turbo use?
The main reason is cleanliness. Ski-Doo E-TEC engines are low-emissions and very high-tech. Clean engine internals and power valves are absolutely vital for proper operation. Interceptor is loaded with detergent additives. These additives prevent carbon and varnish deposits from forming. Interceptor has undergone exhaustive testing to prove its worth in Ski-Doo E-TEC engines. It is ideal for all of the latest 2-stroke motors.
Dominator 2-Stroke Oil is purely a racing oil. It is meant for engines that are frequently torn down. For that reason, it does not need to contain the level of detergents that would be preferable for E-TEC engines. Another vital factor is that snowmobile engines used for recreational riding may not run hot enough to completely burn Dominator’s additive package. This may apply even to turbo-charged engines used in hard trail and mountain riding.
Interceptor will deliver exceptional wear control in turbo-charged 2-stroke engines. It would not be considered a “step down” from Dominator for this application.
Two-Stroke Oil For Turbo Kits With A Separate Oil Tank
Some 2-stroke snowmobile turbo-chargers receive oil directly from the stock oil injection system while some kits utilize an add-on oil tank. Two-stroke oil is often suggested as the turbo lubricant in these auxiliary tanks. AMSOIL Interceptor is an ideal product for use in these cases. One of the main requirements for turbo lubrication is fast flow in cold weather. Interceptor pours down to -56°C (-69°F). It provides consistent turbo bearing protection during cold weather.
AMSOIL Interceptor also offers a wide range of top-end features. These include low-smoke, world-class wear protection, low-friction, resistance to extreme heat, internal corrosion prevention and a competitive price tag.

About Polaris Oil Prices
The prices listed below for Polaris 2-stroke oil products are based on averages from randomly selected Canadian and US Polaris dealers. Retail prices may vary at other locations.
Polaris VES Full Synthetic 2-Cycle Engine Oil Prices
$54.99 in Canada (per US gallon)
$46.99 in USA (per US gallon)
Previously known as “VES Gold Plus”, VES Full Synthetic is Polaris’s most popular 2-stroke oil for their modern snowmobiles. VES Full Synthetic is formulated to keep variable exhaust power valves clean, emit low exhaust smoke levels deliver acceptable wear protection.
We can offer an outstanding upgrade over VES Full Synthetic that provides elite performance and protection for your Polaris snowmobile engine. AMSOIL Interceptor Synthetic 2-Stroke Oil is perhaps the most renowned 2-stroke sled oil in the industry. Interceptor delivers ultra-clean power valves, maximum power output, extreme cold weather performance and low-smoke. Strong positive customer feedback reinforces these claims.
Price of Polaris VES Full Synthetic 2-Cycle Engine Oil Versus AMSOIL Interceptor
Depending on your location, AMSOIL Interceptor can be shipped to your door for 20% to 30% less than Polaris VES Full Synthetic 2-Cycle Engine Oil when using our wholesale programs. We would argue that Interceptor is a significant upgrade over VES Synthetic, so it is really win-win for Polaris owners wanting to use a great synthetic oil.
Polaris VES Race Full Synthetic 2-Cycle Engine Oil Prices
$62.99 Canada (per US gallon)
$52.99 USA (per US gallon)
This is Polaris’s top 2-stroke oil that is designed for racing and high-performance trail use. As VES Full Synthetic covers the needs of most high performance snowmobilers, some Polaris dealers do not stock VES Race Oil. VES Race is designed with a high film strength for extra anti-wear protection. VES Race is basically Polaris’s “severe service” 2-stroke oil.
We offer two AMSOIL synthetic substitutes for Polaris VES Race that we would suggest are a strong upgrade at a better price.
For racing and highly modified snowmobile engines (only!), we offer AMSOIL Dominator Synthetic Racing 2-Stroke Oil. Dominator 2-Stroke has a very high film strength that provides an infallible wear barrier during heavy loads and extended periods of extremely hot operating temperatures. This is the exact formula used by AMSOIL’s snocross racing teams, so you are truly buying professional-grade racing oil with Dominator.
For hard recreational riding with relatively stock engines, go with Interceptor. Dominator 2-Stroke Oil is designed for the extreme heat of racing and/or modified engines. Stock engines will not run hot enough to completely burning off Dominator’s additive package. This applies to all stock engines. AMSOIL Interceptor is a great substitute for Polaris VES Race Oil, no matter how hard you push your stock engine.
Price of Polaris VES Race Full Synthetic 2-Cycle Engine Oil Versus AMSOIL
We can smoke the retail price you would pay for VES Synthetic 2-Stroke Race Oil at your Polaris dealer. When purchasing a case of 4 US gallons, both Interceptor and Dominator are well over of 30% cheaper than VES Race Oil. For most locations, that includes shipping right to your door.
Polaris Premium Blue Synthetic Blend 2-Cycle Engine Oil Prices
$44.99 Canada (per US gallon)
$39.00 USA (per US gallon)
Polaris Premium Blue is a semi-synthetic 2-stroke oil offered by Polaris dealers. It is for snowmobile engines without variable exhaust power valves. This could be for older snowmobiles or newer sleds with the 550cc fan-cooled engine. Premium Blue is designed to provide adequate performance at a moderate price.
We can offer two full full synthetic oils that roundly defeat the semi-synthetic Premium Blue in both performance and price. First we have the “AIO” AMSOIL Injector Synthetic 2-Stroke Oil. It can be used in any snowmobile engine, including those with exhaust power valves. Polaris specifies that Premium Blue should not be used in snowmobile engines with power valves. This implies that it will not burn cleanly enough to prevent deposit formation. AIO Injector offers full synthetic benefits including an exceptionally low cold pour point, robust wear control, low smoke and reduced friction.
At the price point for which Polaris is retailing Premium Blue, our first-rate AMSOIL Interceptor Synthetic 2-Stroke Oil could also be considered as a viable replacement. Interceptor is certainly suitable for older engines, sleds without power valves or the very latest 2-strokes on the market.
Price of Polaris Premium Blue Synthetic Blend 2-Cycle Engine Oil versus AMSOIL Injector Oil
AMSOIL Injector Synthetic 2-Stroke Oil can be shipped to you for around 30% less than you can buy Polaris Premium Blue 2-Stroke Oil. Again this a full synthetic versus a synthetic blend, so in our mind, this is a no-brainer.
The elite quality AMSOIL Interceptor Synthetic 2-Stroke Oil is anywhere from 6% to 15% less money than Premium Blue (depending on your location). Those in the market for Premium Blue may not want to go for this high-end full-synthetic oil. But this illustrates Interceptor’s great value.

Arctic Cat APV Synthetic 2-Stroke Oil Prices
$85.75 (average) in Canada (per US gallon)
$51.16 (average) in US (per US gallon)
APV Synthetic Oil is Arctic Cat’s all-round 2-stroke oil that is suitable for every model except for those equipped with the C-TEC2 600cc and 800cc engines (more on that below). As the name implies, CAT APV Oil is designed to be compatible with Cat’s variable exhaust power valve system called APV (Arctic Power Valves).

Price Of Arctic Cat APV Synthetic 2-Stroke Oil Versus AMSOIL Interceptor
On average, Arctic Cat APV Synthetic 2-Stroke Oil is 43%* more expensive than AMSOIL Interceptor in Canada. In the United States, Cat APV Oil averages 10.5%* more than Interceptor.
*Prices based on AMSOIL Preferred Customer pricing by the case.
Arctic Cat C-TEC2 Synthetic 2-Stroke Oil Prices
$92.41 (average) in Canada, (per US gallon)
$64.65 (average) in US (per US gallon)
Arctic Cat C-TEC2 Synthetic Oil was designed specifically for Cat’s C-TEC2 600cc and 800cc 2-stroke engines. The C-TEC2 engine is a new generation 2-stroke that employs direct injection and precise electronically-metered fuel and oil delivery. The result is an engine that utilizes every drop of fuel and consumes much less oil than traditional 2-stroke engines. C-TEC2 motors deliver exceptional horsepower relative to their displacement. The huge challenge for Arctic Cat engineers was preventing premature wear when so little 2-stroke oil is consumed. Arctic Cat decided to offer C-TEC2 Synthetic Oil to withstand the operating conditions of the C-TEC2.
We offer a direct replacement synthetic oil that is formulated to deliver dependable wear control in today’s direct injection 2-stroke engines. AMSOIL Interceptor Synthetic 2-Stroke Oil is proven performer in today’s technologically advanced two-stroke engines like the Arctic Cat C-TEC2 engine and the miserly Ski-Doo E-TEC engine. Interceptor provides the best engine protection money can buy for Cat C-TEC2 engines that make the most of every drop of 2-stroke oil.

Having a case of Interceptor shipped to your door using our wholesale programs can save you money without compromising performance or engine protection.
*Prices based on AMSOIL Preferred Customer pricing by the case.
Arctic Cat Formula 50 Mineral 2-Stroke Oil Prices
$68.24 (average) in Canada (per US gallon)
$46.99 (average) in US (per US gallon)
Formula 50 Mineral 2-Stroke Oil is offered only for engines that are not equipped with APV variable exhaust power valves. The reason being is that non-synthetic 2-cycle oils do not burn cleanly and have a tendency to clog power valves with carbon deposits. Clogged power valves can lead to power loss and even engine failure. Non-APV engines would include Arctic Cat’s 4000 series engines (500cc), 2000 series engines (565cc), as well as older 2-stroke engines that do not have power valves.
Would you like a full-synthetic substitute for Arctic Cat Formula 50 Mineral 2-Stroke Oil that actually sells for a lower price? We can do that! We suggest using AMSOIL “AIO” Synthetic 2-Stroke Injector Oil instead. It offers all of the benefits you would expect of a full-synthetic 2-cycle oil including low-smoke, reduced engine deposits, exceptional cold weather performance and reduced friction. AMSOIL Synthetic 2-Stroke Injector Oil can even be used in older engines with variable exhaust power valves.
Price Of Arctic Cat Formula 50 Mineral 2-Stroke Oil Versus AMSOIL Synthetic 2-Stroke Injector Oil
The retail price of the conventional Arctic Cat Formula 50 Mineral 2-Stroke Oil Synthetic Oil averages between 29%* (USA) and 44%* (Canada) more expensive than AMSOIL Synthetic 2-Stroke Injector Oil. This includes shipping costs right to your door. AMSOIL Synthetic Injector Oil is a better deal all day long. In fact, the ultra-premium AMSOIL Interceptor is priced very closely to Formula 50.
*Prices based on AMSOIL Preferred Customer pricing by the case.
Conclusion
Oildepot can offer AMSOIL’s full-synthetic 2-stroke oil for your Arctic Cat engine. AMSOIL’s two-stroke oils will improve every operational aspect of your Artic Cat engine at a better price than the oils found at your Arctic Cat dealer. Call us at 1-800-748-5781.
Why Would One Consider A Boat Oil For Snowmobile Use?
There are a couple of reasons why some snowmobilers may wonder about using HP Marine in their winter toys. The first reason is that some sled owners also have 2-stroke boat engines and wish to keep just one product around for both their marine and snowmobile applications. The second possible reason is that Interceptor costs a bit more than HP Marine and some budget-minded riders wish to explore this option.
What Is The Difference Between AMSOIL HP Marine And Interceptor?
HP Marine is an “ashless’ two-stroke oil formula that is suitable for marine applications requiring the NMMA TC-W3 specification. “TC-W3” is an industry rating for outboard two-stroke oils. “Ashless” means that the detergent additives in the oil are non-metallic and will not create any ash deposits in the engine during combustion. HP Marine delivers superior performance in modern direct fuel-injected (DFI) models.
Interceptor is AMSOIL’s offering for high performance, recreational two-stroke engines and is their most popular snowmobile oil. Interceptor is a “low ash” formula for applications requiring the API TC specification. This specification was developed for high output/high RPM two-cycle engines. “Low ash” detergent additives have metallic compounds which form ash residue during combustion. This ash burns up and is evacuated through the exhaust. Interceptor is widely acclaimed for exceptionally clean performance in engines equipped with variable exhaust power valves.
The ashless and low-ash aspects of HP Marine and Interceptor are rarely discussed, but they are vital in drawing a distinction between the two products.
Ashless Or Low Ash- Why Does This Matter?
There is a critical justification for marine two-stroke engine needing ashless detergent additives. Also, there is a reason that high performance two-stroke applications like snowmobiles (and some personal watercraft and motorcycles) require a low-ash formula. It all has to do with operating conditions.
Two-stroke outboards have much lower combustion temperatures than snowmobile engines. They also operate at lower RPM and may see steady throttle positions for extended periods (think trolling). Outboard engines do not have variable exhaust power valves. Ashless formulas are required to prevent engine deposits and spark plug fouling. Low ash oils can create engine depositing and fouled spark plugs in outboard engines.
Snowmobiles engines are put under very heavy loads, have much higher combustion temperature. They also experience widely variable RPM. Most all modern two-stroke snowmobiles engines utilize variable exhaust power valves. Low ash two-stroke oils excel under these conditions that will otherwise strain the limitations of some ashless formulas.
It is important to note that some snowmobile manufacturers strongly urge against using ashless or TC-W3 two-stroke oils in their engines. Ski-doo/BRP is especially vocal on this point.
Does This Mean That HP Marine Is A Lower Quality Oil Compared To Interceptor?
Not at all! It is simply designed to perform under entirely different operating conditions. In fact, AMSOIL does suggest that HP Marine can be used as a secondary option in some applications requiring an API TC (low ash) two-stroke oil. This is due to HP Marine’s high quality synthetic base oil and elite additive package. HP Marine is truly exceptional in its marine domain as it excels in the rigorous Evinrude E-TEC Lean-Mix setting field trial.
Interceptor is one of AMSOIL’s flagship products and is wildly successful in the snowmobile market. Despite its superb protection and performance in high-output two-strokes on dryland, like other low-ash two-stroke oils, it would not be suitable for the operating conditions of the average outboard engine. Excessive engine deposits and fouled plugs could be the result.
Conclusion
So the distinction is simple. Boat- use HP Marine. Snowmobile- use Interceptor for high-performance or newer machines.
For those that own older boat engines and older or non-high-performance snowmobiles, AMSOIL Synthetic Two-Stroke Injector Oil can be used in both applications. This product is designed to excel on water or snow. For Evinrude E-TEC or Mercury Optimax engines, definitely use the elite HP Marine product.
