A Reader Asks: I use AMSOIL Interceptor 2-Stroke Oil in my snowmobile and I’m wondering if it can be used in our older Mercury outboard engine?

AMSOIL INTERCEPTOR Synthetic 2-Cycle Oil

AMSOIL Interceptor is ideal for snowmobiles, but not suitable for outboard engines.

Answer: The short answer is no. AMSOIL Interceptor Synthetic 2-Stroke Oil is the best possible choice for your snowmobile, but it is not appropriate for your outboard engine. While both your boat and snowmobile have 2-cycle engines, it is easy for many to assume that any 2-stroke oil is cross-compatible. This is not the case as notably different 2-stroke oil chemistry is required for each application.

The water cooling, relatively low RPM and tame tuning of outboard engines means that combustion chamber temperatures of your outboard are drastically lower than the internal operating temps in your snowmobile engine.

Because of this difference, outboard engines require a two-stroke oil with the NMMA TC-W3 designation. TC-W3 oils have “ashless” detergents that keep the combustion chambers, exhaust ports and spark tips clean. Ashless oils are designed to prevent deposit build-up and spark plug fouling in the outboard engines.

Your snowmobile requires a “low-ash” two-stroke oil which is usually identified by the API TC specification. Low-ash detergents form a trace amount of ash deposit upon combustion that is promptly ushered out of the exhaust pipe. Low-ash detergents do an outstanding job of keeping the combustion chambers, variable exhaust power valves and spark plug tips clean in hot-running, high strung snowmobile engines.

Using a low-ash 2-stroke oil formula in your outboard would be inviting deposit build-up in your exhaust ports and potentially fouled plugs. Over time, this is a recipe for very poor performance.

Conversely, ashless 2-stroke oils for outboard engines are ill-equipped for the high-heat, high RPM existence of snowmobile engines. Ashless TC-W3 marine 2-stroke oils are optimum for outboard engines, but will form very troublesome deposits in snowmobile engines.

Here are some better AMSOIL 2-stroke options for your outboard engines.

A reader asks: I have a 2012 Sea-Doo RXP-X 260 with the 1493cc supercharged/intercooled 4-TEC engine. I know some Sea-Doo owners use Shell Rotella 10W-40 diesel oil and others swear by BRP XPS Semi-Syn Oil? What is the correct AMSOIL engine oil recommendation?

AMSOIL 10W-40 Formula 4-Stroke® Marine Synthetic Motor Oil

AMSOIL 10W-40 Marine is a superb choice for Sea-Doo supercharged 4-TEC engines.

Answer: As you have the supercharged Rotax 4-TEC engine, using the proper motor oil is vital. AMSOIL 10W-40 Formula 4-Stroke Marine Synthetic Motor Oil covers all of the bases in terms of protection and performance for your engine and may very well be the best choice on the market.

The first consideration for your engine is that the motor oil is compatible with the slip-clutch on your supercharger. Regular motor oil for gasoline-powered cars and trucks contains friction modifiers which can cause excessive supercharger slippage. AMSOIL Marine 10W-40 does not contain friction modifiers and it possesses the ideal frictional properties for consistent supercharger performance. The synthetic makeup of this product also fights extreme heat, so the service life of supercharger slip washers and bearings is optimized.

While the Sea-Doo owners using Shell Rotella diesel oil may have cheap oil, AMSOIL 10W-40 Formula 4-Stroke Marine Synthetic Motor Oil not only offers 100% synthetic performance, it also delivers an anti-rust and corrosion package that is designed to protect marine engines both in-season and during storage. This measure of protection alone is well-worth the upgrade to AMSOIL Marine 10W-40. AMSOIL products have always performed well versus BRP XPS Oils, so we can confidently suggest that AMSOIL Marine 10W-40 will be a solid upgrade over the partial-synthetic XPS Summer Grade 4-Stroke Oil.

For Sea-Doo owners of Rotax 4-Tec models from 2004 to 2007 that still have ceramic slip washers on their superchargers, AMSOIL 10W-40 Formula 4-Stroke Marine Synthetic Motor Oil is 100% compatible with this material and will not weaken these washers. There was a myth out there ten years ago suggesting that synthetic oil could damage these ceramic washers, but AMSOIL performed extensive testing to debunk this theory.

Most Sea-Doo owners of 2004-07 models have upgraded their supercharger’s ceramic slip-clutch washers to metal (or should be considering this upgrade service). Regardless of whether your model has ceramic or steel supercharger washers, AMSOIL Marine 10W-40 will be perfect for your Sea-Doo 4-TEC engine.

We can offer AMSOIL 10W-40 Formula 4-Stroke Marine Synthetic Motor Oil at the lowest price in Canada or the United States. Contact us for a wholesale price list using the form on this page or call us at 1-800-748-5781.

A few years ago, we posted an article on How To Polish Tarnished Headlights Using A Mother’s Powerball Mini. While this process is effective on headlights with minor blemishes, there are cases where a more intensive course of action is required. When headlight lenses are moderately to severely hazed, really only one method is truly effective and that is using automotive-grade sandpaper. This easy, inexpensive repair can restore the headlight lens and dramatically improve night driving safety. Below are the steps to perform this task along with an image slideshow.

While you may be hesitant to take to your headlights with sandpaper, don’t be concerned. The sandpaper used is of a very fine grit which will polish off the tarnished plastic, as well as smooth out minor dents and imperfections. The key throughout the sanding process is to constantly keep the headlight wet as you sand. This is a wet sanding process, so if you never let the work area dry out while you polish, all will be well.

While we are confident on the safety of this process, go through the following steps on a corner of your headlight first before performing this on the whole lens. All of the items needed are inexpensive and available at any auto parts store.

Items Needed

  • Automotive sandpaper sheets in 1000, 2000 and 3000 grit (this is the finest grit).
  • Masking tape for painting
  • A water spray bottle
  • Metal polish or headlight polish.
  • Meguiar’s PlastX Plastic Polish
  • Rags, polishing cloth or paper towels.

 

Step One
Soak the sandpaper sheets in a pail of water for 20 minutes as you prepare to start. They soak up the water and improve the wet sanding performance.

Step Two
Clean off headlight lens of any dirt, dead bugs or grit of any sort.

Step Three
Using painting masking tape, mask off surrounding painted and grill areas to prevent accidental damage.

Step Four
Spray the headlight with water and using the 1000 grit sandpaper, sand in a horizontal direction using a short, fast polishing motion with light to moderate pressure. After you have completed the headlight in a horizontal direction, start again in a vertical direction until you have covered the damaged area. Do not sand in a swirling motion. Again, keep the area wet at all times. Perform the sanding process with the 1000 grit paper until you are confident that you have removed most of the tarnished material.

Step Five
Wipe down the headlight lens and inspect your work. The lens will have a definite haze, so do not be alarmed by this. Start sanding with the 2000 grit sandpaper, again covering the lens in a complete horizontal direction and then crossing it in a vertical direction. Remember to spray the lens with water to prevent dry sanding while you work. Sand with the 2000 grit paper several times.

Step Six
Wipe down the lens and then start the wet sanding process with the 3000 grit paper. This fine sandpaper grit performs the final polishing. Do keep in mind the lens with still be hazed when you complete the sanding, but the headlight polish and final polishing with Meguiar’s PlastX will remove this.

Step Seven
Polish the lens with metal polish or headlight polish, we used Fix-It Headlight Polish from Walmart. Go through this step several times.

Step Eight
Complete the final polishing with several applications of Meguiar’s PlastX.

Bonus Tip
Meguiar’s PlastX is a very handy item to have around your shop and home. We have used it to reduce scratches on car radio displays and cordless phone displays. PlastX also revitalizes taillight lenses. It will even safely remove rust on shower surrounds. This is a high quality product that we have appreciated for many years.

Note: We do not sell any of the items listed in this article.

A reader asks: I’ve got a 2003 Sea-Doo Sportster LE Jet Boat with the “947” 951cc Rotax 2-stroke engine. What would be the correct AMSOIL 2-stroke oil for this engine? If this helps, here is an excerpt from my owner’s manual:

Caution: Do not use NMMA TC-W, TCW-2 or TCW-3 or other ashless type two-stroke oils.

Answer: Sea-Doo Rotax two-stroke engines are bit unique in that they require an oil designed for the API TC specification rather than an oil with the NMMA TC-W3 specification (which is commonly specified for marine engines). So with this being the case, our recommendations are either AMSOIL Interceptor Synthetic 2-Stroke Oil (premium choice) or AMSOIL “AIO” Synthetic 2-Stroke Injector Oil, which is a great replacement for XPS semi-synthetic or mineral 2-stroke oil. Let’s explore BRP/Sea-Doo’s reasoning for suggesting 2-stroke oils that differ from other personal watercraft and boat engine makers.

What Is The Difference Between API TC and NMMA TC-W3 2-Stroke Oils?

AMSOIL INTERCEPTOR Synthetic 2-Cycle Oil

AMSOIL Interceptor Synthetic 2-Stroke Oil is a premium replacement oil for Sea-Doo Jet Boats.

The main difference between the two specifications is the type of detergent ingredients used. Detergent additives maintain clean combustion chambers and exhaust ports. NMMA TC-W3 is a spec for marine applications that use “ashless” detergents. API TC is a 2-stroke oil specification mainly for dryland use (such as dirt bikes or snowmobiles) and these oils have “low ash” detergent additives. Low ash 2-stroke oils will create a small amount of ash during combustion that is sent out of the exhaust. Ashless 2-stroke oils do not create any ash residue during combustion.

The reason that marine outboard engines and dryland engines such as dirt bikes require these different detergent types in their 2-stroke oils is in the way they operate. Outboard engines have much lower combustion temperatures than dirt bikes or snowmobiles. They also generally see much more stable RPM levels. In outboard engines, ashless 2-stroke oil formulations will burn cleaner under these lower temp operating conditions, whereas API TC low ash oils can foul spark plugs and create deposits.

In high-output dirt bikes and snowmobiles, low-ash detergent additives work very well and maintain clean combustion chambers under these harsh operating conditions. Ashless additives simply aren’t capable of maintaining clean engine internals when exposed to extreme heat.

Long story short, TC-W3 oils burn cleaner in outboard engines and API TC oils burn cleaner in snowmobile and dirt bike engines. Using API TC oils in outboard engines or TC-W3 oils in dryland applications can result in fouled plugs and dirty engine internals.

Why Is NMMA TC-W3 A Problem In BRP/Sea-Doo Rotax Engines?

Sea-Doo engines such as the 947 are derived from the Ski-Doo snowmobile engine family. These engines run hot, create big horsepower relative to their displacement and have variable exhaust valves. The detergents in ashless 2-stroke oils do not have the capacity to maintain clean combustion conditions in these potent engines. The result would be dirty “RAVE” variable exhaust values and performance-sapping deposits. Engine damage could also result. Despite the fact that your Sea-Doo is operated on water, an API TC 2-stroke oil is far more appropriate due to the way your engine is designed and the way it is operated.

Oil Testing: Interceptor vs BRP XPS-2 Synthetic 2-Cycle Oil

Sea-Doo dealers and some message board warriors will insist that BRP XPS-2 Synthetic 2-Cycle Oil is the only oil you should ever consider for your Rotax 2-stroke engine. XPS 2-stroke oils from your Sea-Doo dealer are definitely not the only oil that is compatible with your Sea-Doo engine. We offer a 100% synthetic option that has been proven in testing against XPS-2 and has also been confirmed to be very effective in Rotax engines. Interceptor is far less expensive than XPS-2 Synthetic 2-Cycle Oil while offering improved lubrication (which improves power output) and engine deposit control that is equal to or better and than XPS-2 Synthetic. While the testing is performed in Ski-Doo snowmobiles with the latest Rotax DFI engines, the results are very much applicable to Sea-Doo engine use. See AMSOIL Interceptor Versus BRP XPS-2 Synthetic 2-Cycle Oil in Ski-Doo E-TEC Engines.

We can offer the premium AMSOIL Interceptor 2-Stroke Oil for your Sea-Doo Jet Boat or 2-stroke personal watercraft models at a price that is far better than the XPS-2 synthetic offerings at your Sea-Doo dealer.

Kyle and Jarret Biro once again prove their worth against Western Canada’s best motocross racers.

As we mentioned in our profile of Kyle Biro and his race bike, one of his big goals for 2015 was to have a good showing at the Western Canadian Amateur Nationals at Raymond, Alberta. The racing event was held this past weekend and to say that he accomplished the mission would be an understatement. Biro did not miss a mark all weekend winning Western Canadian titles in the MX2 Intermediate, MX3 Intermediate and Schoolboy classes. Not only did Kyle win the overall titles, he won all nine motos in the process. Kyle guided his Yamaha YZ250F to holeshots in all but one moto, essentially winning every race from wire to wire. For this impressive performance, Yamaha Canada awarded Kyle with a factory support ride for 2016. Kyle will receive a Yamaha YZF motocross bike for the season and along with parts support.

Kyle Biro At Western Canadian Amateur Nationals 2015

Kyle Biro lands a jump en-route to a sweep of all of his classes at the 2015 Western Canadian Amateur Motocross Nationals at Temple Hill Motorcycle Park.

Kyle Biro is on great form for his next target being the Trans Can Grand National Championships at Walton, Ontario, which takes place next month. Kyle will also participate in the Walton round of the CMRC Pro Nationals which takes place directly after the Trans Can amateur event. As this is Kyle’s first full season as an intermediate amateur, he can compete as an intermediate classified rider and still take part in National Pro races.

Not to outdone, Jarret Biro also had a very strong showing against Western Canada’s best with two podiums. Jarret finished third overall in both the MX2 Junior and the Schoolboy classes. He also finished 7th overall in the MX3 Junior class. A second moto DNF (due to a collision with another competitor) dragged down a strong 3rd in the first moto and 2nd in the third moto.

Jarret also shifts his focus on the Canadian Amateur Nationals as he aims to repeat his impressive podium performance of 2014 against Canada’s best young racers.

The Biro boys have depended on AMSOIL products for several seasons now. Kyle is running the AMSOIL 10W-40 Synthetic Dirt Bike Oil in his four-stroke YZ250F, while Jarret runs AMSOIL Dominator Synthetic Two-Stroke Oil (mixed at 40:1) in his Yamaha YZ125 engine and AMSOIL Dirt Bike 10W-40 in his transmission.

Like most other European car makers, Mercedes-Benz has long had their own motor oil specifications. While some European car owners may grumble about the fact that finding the correct motor oil for the car can be inconvenient (and possibly expensive), these motor oil standards do remove any doubt from the buying process.

Below is an explanation of each Mercedes motor oil standard along with the AMSOIL European Formula Synthetic Motor Oil that complies with the specification. We sell four different European engines oils formulated to meet the specifications for Mercedes-Benz cars and Sprinter diesel vans.

MB 229.1

This obsolete Mercedes motor oil specification was devised for both gasoline and diesel engines back in the late 1990s. The MB 229.1 spec dictated minimum standards in terms of motor oil detergent levels and soot dispersant content. Motor oils suitable for the MB 229.1 specification required high SAPS (Sulfated Ash, Phosphorus and Sulfur) levels. The AMSOIL motor oils that cover the MB 229.1 specification are AMSOIL European Formula “Full-SAPS” 5W-40 Synthetic Motor Oil and AMSOIL European Formula “Full-SAPS” 0W-40 Synthetic Motor Oil.

MB 229.3

For gasoline and diesel engines covering model years from 1998 to 2004, MB 229.3 compliant motor oils also require high SAPS levels. MB 229.3 differs from the 229.1 spec in that it an MB 229.3 engine oil must also be capable of longer oil change intervals and also must reduce friction to improve fuel economy by a percentage point over 229.1. For cars requiring MB 229.3, use AMSOIL European Formula “Full-SAPS” 5W-40 Synthetic Motor Oil or AMSOIL European Formula “Full-SAPS” 0W-40 Synthetic Motor Oil.

MB 229.31

This specification came into effect during the 2003 model year for both gasoline and diesel engines. MB 229.31 motor oils are required to have medium SAPS levels in order to be compatible with Mercedes Bluetec diesel exhaust particle filters and the catalytic converters on the gasoline engines. Higher SAPS levels of some non-compliant motor oils can foul these emission components and cause operational problems. MB 229.31 motor oils must be designed for a service life of up to 15,000 km. AMSOIL European Formula “Mid-SAPS” 5W-40 Synthetic Motor Oil is suitable for cars and Sprinter vans requiring the MB 229.31 engine oil standard.

MB 229.5

For both gasoline and diesel engines, the MB 229.5 specification was released in mid-2002. This specification was designed to be an upgrade over the MB 229.3 spec in terms of fuel economy and oil change interval duration. MB 229.5 motor oils are formulated with high SAPS additive levels. AMSOIL European Formula “Full-SAPS” 5W-40 Synthetic Motor Oil and AMSOIL European Formula “Full-SAPS” 0W-40 Synthetic Motor Oil cover the Mercedes 229.5 engine oil standard.

MB 229.51

Introduced in 2005, MB 229.51 was designed for longer oil life over the MB 229.31 specification in gasoline and diesel engines. MB 229.51 oils must be capable of staying in service for 20,000 km. MB 229.51 oils must have low to moderate SAPS levels to be compatible with catalysts in gasoline engines and diesel exhaust particle filters. Both the AMSOIL European Formula “Low-SAPS” 5W-30 Synthetic Motor Oil and the AMSOIL European Formula “Mid-SAPS” 5W-40 Synthetic Motor Oil are designed for MB 229.51 service.

AMSOIL European Car Formula Full-SAPS Synthetic 0W-40 Motor OilAMSOIL has released a brand new 0W-40 engine oil for many popular European applications with gasoline or diesel engines. The AMSOIL European Full-SAPS Synthetic 0W-40 Motor Oil rounds out AMSOIL’s extensive line of Low-SAPS, Mid-SAPS and Full-SAPS engine oils.

Why Is AMSOIL Now Offering A European 0W-40?

AMSOIL already has a 5W-40 European Full-SAPS Oil, so why did they choose to offer a similar 0W-40 Full-SAPS version? The reason is that 0W-40 is recommended for some European cars in winter and it is a fairly popular viscosity in the European motor oil category.

This new Euro 0w-40 meets the following worldwide specifications.

  • Volkswagen 502.00, 505.00
  • BMW LL-01, LL-98
  • Mercedes-Benz 229.1, 229.3, 229.5
  • Porsche A40
  • ACEA A3/B3, A3/B4
  • Renault 0710, 0700
  • API SN/SM

AMSOIL European Full-SAPS Synthetic 0W-40 Motor Oil is an excellent substitute for the following European engine oils.

  • Castrol Edge 0W-40 Synthetic Motor Oil
  • Champion High SAPS European 0W-40 Motor Oil
  • Lucas Oil Synthetic 0W-40 Motor Oil
  • Mobil 1 European Car Formula Synthetic 0W-40 Motor Oil
  • Red Line High Performance Synthetic 0W-40 Motor Oil
  • Shell Helix Ultra 0W-40 Motor Oil
  • Shell Helix Ultra Professional AV 0W-40 Motor Oil

Can AMSOIL European 0W-40 Be Used in Summer?

Absolutely. Keep in mind that this motor oil falls into the 40-weight viscosity category at operating temperatures. This 100% synthetic 0W-40 will not breakdown or thin out when faced with extreme summer heat, heavy loads or turbo-charged engines.

Where Can I Buy AMSOIL European 0W-40 Motor Oil?

Right here! Oildepot can sell AMSOIL European Full-SAPS Synthetic 0W-40 Motor Oil at the best price in Canada and the United States. We ship from 2 warehouses in Canada and 11 in the USA. Contact us with the form on this page or call us at 1-800-748-5781 and let’s start the conversation.

Can AMSOIL’s motorcycle and ATV oils be used in other categories?

AMSOIL Metric Synthetic 10W-40 Motorcycle OilA reader asks: I’m using AMSOIL Metric 10W-40 Synthetic Motorcycle Oil in my Honda CBR600RR. We’ve also got a dirt bike and ATV that call for 10W-40. Can I use Metric 10W-40 in these bikes as well?

Answer: Absolutely. AMSOIL Metric 10W-40 is quite capable in dirt bike or ATV engines and transmissions. Until recently, the “MCF” Metric 10W-40 formula was AMSOIL’s only 10W-40 option for dirt bikes, street bikes and ATV’s. Note that it was used quite successfully in professional racing (both road racing and motocross).

AMSOIL released the off-road-specific Dirt Bike Synthetic 10W-40 earlier this year and its main attribute is the ability to combat clutch fade and slippage under extreme loads. The Metric 10W-40 Motorcycle Oil will provide superb service in dirt bikes, but the Dirt Bike formula is a bit of an upgrade for racing or extreme off-road operating conditions.

As for ATV’s, AMSOIL also released an ATV Synthetic Oil Series earlier this year (including a 10W-40). It too is formulated for severe off-road conditions. Metric 10W-40 would certainly provide commendable performance and protection and would be an upgrade over other ATV oil brands.

All this being said, the ATV 10W-40 or Dirt Bike 10W-40 can also admirably replace Metric 10W-40 in your street bike. The common thread of all of these products is that they are suitable for wet-clutch service and have an elite synthetic composition. Suppose that you need the robust staying power of the Dirt Bike formula for a motocross bike, but you also have a street bike and ATV and want to keep only one product around for convenience. You could easily use Dirt Bike 10W-40 in the street bike and ATV and the same could be said of the ATV 10W-40.

The bottom line is that all of these products are formulated to provide great performance in their respective category, but all of these applications require an engine oil with similar performance characteristics. So one product can be used in street bikes, ATV’s and dirt bikes, provided that they all call for the same viscosity.
