AMSOIL Interceptor is the Jet Ski Oil

Better than OEM in Performance and Better in Price

Jet Ski 2-cycle Injector Oil Choices

Here at the Sioux Falls store we do sell a good amount of our 2-cycle injector oils for sleds in the winter and even more for Jetskis in the summer. The main product we’ll cover here is our top recommendation, AMSOIL Interceptor 2-Cycle Injector Oil.
Seems we hear from Yamaha Waverunner customers the most, then the Sea-Doo. Both sell a injector oil which as the customer soon finds out is expensive and offers no advantage to ours.
AMSOIL is the company that makes the 2-cycle injector oil one of it’s primary subjects as for technology because AMSOIL’s employees are MAJOR Snowmobile users and Jet-Skis use the same engines. AMSOIL also dominates the 2-stroke oil industry for all heavy use where these machines are needed to either win races or used for decades in work..


AIT1GSo that said, there is no reason to spend more money for an inferior OEM product such as the Ski-Doo XPS2. AMSOIL (here at the Sioux Falls Store) we sell three products which meet or exceed it’s performance level at various price points. First, the AIO Injector Oil which was designed to be similar to all OEM products only with AMSOIL’s better quality additive packages for about $15 less per gallon, then #2  the Interceptor (AIT) is the step up or designed to be the pinnacle of the industry. It’s about 90% of our sales and power valve life between cleanings is more than twice as long and less smell/smoke – better quality for at least $6 less per gallon.

Two Grades of injector oils  – Best: AMSOIL (AIT) Interceptor and AMSOIL (AIO) 2-cycle Injector Oil multi-purpose. Use the Dominator for racing.

AMSOIL INTERCEPTOR Synthetic 2-Stroke Oil is engineered for use in direct-fuel-injected (DFI), electronic-fuel-injected (EFI) and carbureted two-stroke Jet-Skis (and Snowmobiles), including those made by Yamaha, Kawasaki,  BRP*/Ski-Doo Sea-Doo* (Rotax* E-TEC* engines), Arctic Cat* (C-TEC 2) and Yamaha*.

Use where API TC oils are specified. Use as injection oil or 50:1 premix (2.6 oz. per U.S. gallon of gas). INTERCEPTOR is compatible with most conventional and synthetic two-stroke oils; however, for best performance, mixing oils should be minimized.

Jet Ski Sioux Falls Fun

The good news is that many powersports retailers and service shops are now carrying the Interceptor due to customer demand.  If you own or manage inventory at a dealer give us a call. Customers love the fact that the AMSOIL product does not affect factory warranties and by a wide margin offers less needed long term maintenance due to the reduction of deposits in the intake or fuel (exhaust power valve) system.

Powersports and Small Equipment Fuel Treatment

One Clear Choice in Engine Deposit Control

Turbos and GDI engines suffer from Deposits. Take no chances! Use AMSOIL

Leading the Field In Deposit Protection

Quality is Key

5W-30 Signature Series has you protected

Testing proves AMSOIL Signature Series 5W-30 Synthetic Motor Oil provides more complete protection against damaging deposits than its competitors.

The push toward smaller, fuel-efficient yet powerful engines has driven the development of several key technologies. Gasoline direct injection (GDI) and turbochargers are now common features of passenger cars and light trucks. By 2020, industry experts predict that nearly every new vehicle will feature GDI technology, and the vast majority will be turbocharged. While these advanced technologies enhance performance, they also present serious challenges to motor oil.

The Turbocharger Trade-Off

Turbochargers push more air into the engine’s combustion chamber, providing better fuel-economy and performance but also creating intense engine temperatures. They often operate above 150,000 rpm on exhaust gases exceeding 1000°F. These extreme conditions cause some motor oils to break down and solidify into harmful deposits.

Vehicle manufacturers have long recommended different service intervals based on “normal” or “severe” driving conditions. Turbocharged vehicles are automatically included in the severe service category due to the extreme heat they generate. Motor oil with unique properties is required to combat the effects of intense temperatures.

Proof of Protection

AMSOIL Signature Series 5W-30 Synthetic Motor Oil was tested against two competing brands to determine its level of protection against deposit formation in high-heat applications.

 protects against harmful deposits on turbochargers 4X better than Mobil1® Extended Performance and 3.6X better than Royal Purple® in industry-standard testing*.The TEOST 33C test (ASTM D6335) is an industry-standard bench test that simulates turbocharger operating conditions. According to the American Society for Testing and Materials (ASTM), it is “designed to predict the high temperature deposit forming tendencies of an engine oil.” To meet the API SN Resource Conserving and ILSAC GF-5 motor oil specifications that are often recommended by vehicle manufacturers, a 5W-30 motor oil must limit total deposit formation to 30 mg or less.

AMSOIL Signature Series 5W-30 Synthetic Motor Oil held the total weight of deposits to 7 mg, well under the 30 mg limit required by the API and ILSAC, while Royal Purple® API 5W-30 and Mobil1® Extended Performance 5W-30 came in just under the limit at 25.4 mg and 28.2 mg respectively. Signature Series 5W-30 Synthetic Motor Oil protects against harmful deposits on turbochargers 4X better than Mobil1® Extended Performance and 3.6X better than Royal Purple® in industry-standard testing*.

*Based on independent, third-party testing of AMSOIL® Signature Series 5W-30, Mobil1® Extended Performance 5W-30 and Royal Purple® API 5W-30 in the ASTM D6335 bench test required by the API SN Resource Conserving specification.

Test results represent the formulations available as of April 2016. Formulations were coded to eliminate bias during testing and samples were tested in random order. An appropriate number of trials of each oil were run to produce results at or above the 95 percent confidence level when compared to AMSOIL Signature Series 5W-30 Synthetic Motor Oil.


Sioux Falls Store Note:

The competition knows these attributes wouldn’t make a difference to the average driver so it is a major needed cost to the stock holders. And that demonstrates precisely the utter difference from AMSOIL and the rest. AMSOIL’s decision makers at the Superior, WI headquarters have had the goal to provide the best uncompromising product for protection and performance regardless of the cost.  Lesser base stocks will suffice the 75% of drivers who are not true enthusiasts or don’t consider operating costs over the long term. Do the math, feel the power and get years more from that engine and transmission. It’s your money – see it go further. AMSOIL is really in your best interests. Use and spread the news about these products!! They do work as advertised!

AMSOIL's Performance in Evinrude E-TEC 2-Cycle Marine Engines

Outboard Protection at a Better Price

AMSOIL is fast becoming the standard in the 2-stroke outboard oils just based on performance. Several OEM’s have a niche requirement for 2-cycle oil that often scares the customer into believing the OEM recommended oil is the only safe choice. While there are many inferior products out there, you can be assured AMSOIL will always be at the front of the technology. And Sioux Falls Marine owners of ALL makes and models will benefit. Make the Synthetic Warehouse your HQ for all your marine lubricants. Although the AMSOIL HP Marine 2-Cycle Injector Oil is covered here, all of our marine two stroke oils perform with the same “built to outperform” commitment.

AMSOIL products are warranty secure so you can rest easy that our products will not cause issues with service requirements in and out of warranty – Guaranteed! Often our product will


The various departments at AMSOIL also work to stay ahead of the equipment trends, OEM requirements and prepare years in advance for specific EPA driven emission requirements well before it’s required for the manufacturer to make the change.

Marine E-TEC™ Field Study

AMSOIL HP Marine Synthetic 2-Stroke Oil provides excellent protection in Evinrude® E-TEC marine engines programmed to the lean-mix setting.

Two Cycle Test Overview

Evinrude® E-TEC™ marine engines are unique in that they offer an alternative, lean-mix setting that allows the engine to use less oil. Whether programmed to operate at the standard mix ratio or reprogrammed to the lean-mix setting, E-TEC engines use sophisticated electronic equipment to monitor conditions, including rpm and throttle position, to determine the appropriate gas-to-oil mixture. To use the lean-mix setting, however, customers must have their engines reprogrammed by an Evinrude dealer and agree to use Evinrude XD100™ oil exclusively, often at a higher cost compared to other oils. Bombardier Recreational Products (BRP®), the manufacturer of Evinrude E-TEC engines, has not established a performance specification against which to qualify other oils.


Determine through real-world field validation if AMSOIL HP MarineTM Synthetic 2-Stroke Oil meets the increased performance needs of reprogrammed Evinrude E-TEC engines operating on the lean-mix setting. Further determine if consumers can safely use HP Marine Synthetic 2-Stroke Oil in E-TEC applications in place of Evinrude XD100 2-Cycle Oil.


In conducting this field study, AMSOIL partnered with SEA-TOW®, a marine rescue organization specializing in non-emergency calls for assistance. Based in Naples, Fla., SEA-TOW typically tows large marine vessels, including yachts and sport cruisers. The engines that power their towing vessels routinely encounter heavyduty, high-stress operation and provide the ideal environment for testing motor oils. Both Evinrude 250 hp E-TEC engines used in the study were initially operated on the standard oil injection setting for 28 hours. An Evinrude dealer then reprogrammed both engines to operate on the lean-mix setting for the duration of the study. The starboard engine’s oil reservoir was filled with AMSOIL HP Marine Synthetic 2-Stroke Oil, the portside engine’s oil reservoir with Evinrude XD100 2-Cycle Oil. The validation period lasted a total of 534 hours; approximately 240 hours were spent under severe-service conditions when the SEA-TOW boat towed marine vessels. The engines were closely monitored for the duration, and upon completion, both were disassembled and rated by a calibrated ASTM rater who evaluated each engine based on NMMA TC-W3 criteria for two-cycle marine engines. Merit ratings for each set of components (e.g. piston skirts, piston rings, etc.) were determined using the appropriate techniques and rating scales as defined in the Coordinating Research Council, Inc. Deposit Rating Manual No. 20. The evaluation included an examination of the condition of all engine parts. Some components received a merit rating based on a 1-10 scale, with 10 representing a component free of defects and 0 representing catastrophic distress. Others received merit ratings indicating the percentage of an area with defects (e.g. the percentage piston skirt area containing scuffing). The average merit rating of each group of components is shown in this study.

Note: Test results describe and represent the properties of two-stroke oils tested from February 2009 through April 2010. Results do not apply to any subsequent reformulations of such oils or to new oils introduced after completion of the testing.

And remember: Sioux Falls Marine owners of ALL makes and models will benefit from AMSOIL in cost and performance. Make the Synthetic Warehouse your HQ for all your marine lubricants. Gear, 2-cycle, 4-stroke and fuel system maintenance. Amsoil compared to expensive Evinrude XD100

Sioux Falls boaters save on 2-cycle Marine oil

The pistons in both engines received nearly identical high merit ratings for varnish, indicating both oils excelled at inhibiting varnish formation. Scratching refers to the alteration of the skirt surface in the form of sharp linear depressions from lapping of mating surfaces by fine particles suspended in the lubricant, fuel, air or embedded in a surface, while scuffing appears as a matte finish. The presence of scuffing is commonly lubricant-related. In both engines, scratching was present at trace to very light levels, represented by the low percentage ratings. Both oils completely prevented piston skirt scuffing, earning perfect ratings of 0.00 percent scuffing.

Amazing 2-cycle injector oil results

Deposits on the piston rings can cause ring sticking and consequent power loss. The top rings and second rings in both engines earned perfect merit ratings of 10.00, demonstrating no piston ring deposits. Merit ratings for crown land and second land deposits were similar for both engines.

Evinrude Head Deposits and Carbon

Excessive cylinder head deposits are undesirable and can negatively affect engine performance. Both oils earned high ratings for deposit control, indicating good cleanliness properties.

Evinrude piston crowns and undercrowns

While undercrown deposits do not impede performance, heavy piston crown deposits can cause preignition and consequent poor performance. Two-cycle oils must resist heavy deposit formation on the piston crown caused by the high temperatures inside the combustion chamber. HP Marine demonstrated strong performance in the area of piston crown deposits.


Connecting rod assembly components are exposed to elevated temperatures and pressures that can rupture the oil film, leading to metal-to-metal contact and wear. The wristpins, crankpin rod bearings and wristpin rod bearings in both engines demonstrated trace to light levels of wear and were found to be in “good” condition according to the calibrated ASTM rater. Deposits on all components were limited to levels not adversely affecting performance.

connecting Rods 2-cycle Evinrude ETEC

The wristpin and crankpin bearing races undergo constant rotational stress, inviting wear. Bearing races in both engines demonstrated trace to light levels of wear and were found to be in “good” condition according to the calibrated ASTM rater. Deposits were limited to low levels in both engines.

Cylinders - totally clean E-TEC

Carbon deposit buildup in the exhaust ports restricts air flow and can cause reduced power and poor overall performance. Both engines displayed virtually no exhaust port blocking, represented by the low percentages. Deposits were likewise minimal, with ratings near perfect 10s. In the area of cylinder bore scuffing, both oils limited metal-to-metal contact and achieved perfect scores of 0.00 percent. The cross-hatch pattern remains visible on the cylinder walls of both engines.

AMSOIL HP Marine Synthetic Two Stroke Oil

Evinrude XD100 2-cycle Synthetic Oil

The crankpins and main bearing journals experience elevated pressures during operation and represent common suffering points. In both engines, the crankpins and main bearing journals demonstrated trace to light wear and were found to be in “good” condition according to the calibrated ASTM rater. Ratings for deposits were nearly perfect for both engines.

Crankshaft Main Bearings Conditions

The main bearings experience intense pressure and represent a common area where metal-to-metal contact can occur. Both oils limited wear to trace to light levels and the bearings were found to be in “good” condition according to the calibrated ASTM rater. Both oils nearly eliminated deposits as well.


As demonstrated in real-world, severe-service testing, AMSOIL HP MarineTM Synthetic 2-Stroke Oil meets the stringent performance needs of Evinrude® E-TEC TM marine engines programmed for reduced oil consumption. Operated simultaneously with an engine lubricated with Evinrude XD100, an identical engine lubricated with HP Marine demonstrated strong performance and excelled in critical-component lubrication. The cylinder bores, for example, demonstrated 0.00 percent scuffing, while the main bearings demonstrated only trace to light wear. The engine also displayed no ring deposits, earning perfect merit ratings. Finally, HP Marine effectively limited deposits throughout the engine and met the increased performance demands required by the lean-mix setting. Results prove the effectiveness of AMSOIL HP Marine Synthetic 2-Stroke Oil in Evinrude E-TEC applications.

AMSOIL fully supports the use of HP Marine as a replacement for Evinrude XD100 in Evinrude E-TEC engines, and warrants its use according to the AMSOIL Limited Liability Warranty (G1363).
