AMSOIL 5W-30 Synthetic Small Engine OilA reader asks: Our company has several Generac generators that run on liquid propane and natural gas. These generators run in severe winter temperatures and summer heat. Do you have an engine oil that will be suitable for all-season use and is compatible with LP and natural gas fuels?

Our answer: Yes, we have the perfect motor oil for your LP/natural gas-powered Generac generators. AMSOIL 5W-30 Synthetic Small Engine Oil ticks every box. This product is a high-quality replacement (and a tremendous upgrade) for the conventional Generac SAE 30 Motor Oil.

What Makes A Good Motor Oil For Generac Generators?

Here are the features that make AMSOIL 5W-30 Synthetic Small Engine Oil the perfect oil for generator applications.

  • Suitable for engines powered by LP, natural gas, gasoline or diesel fuels
  • Delivers commercial-grade wear protection
  • Pours down to -44°C (-47°F) for excellent winter start-up protection
  • Robust synthetic chemistry withstands long days under load
  • Resists oil consumption and deposit formation under extreme heat
  • Contains anti-rust and corrosion ingredients for protection during periods of inactivity

Can Car Engine Oil Be Used In LP Or Natural Gas Generator Engines?

Automotive motor oils are not suitable for liquid propane or natural gas-powered generators. Car motor oil would tend to break down relatively quickly and be prone to oil consumption. Passenger car motor oils are simply not designed to work with LP or natural gas fuels.

To sum up, we can’t think of any reason as to why AMSOIL 5W-30 Synthetic Small Engine Oil would be anything but perfect for your generators.

Photo Credit: Sledmagazine.com

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.

A reader asks: We have a variety of compressor and hydraulic systems in our plant. Our technicians frequently complain about difficulty with seeing clear oils in sight glasses. We’ve even had situations where production has been temporarily halted because we mistakenly believed that a reservoir was below the safe level. Do you offer a coloring that darkens the oil? It would help us with “hard to see” oil levels on sight glasses.

Our Answer: There is a product for coloring oils that is readily available. Heavy-equipment maker Caterpillar offers oil-soluble dyes that are suitable for most compressor, hydraulic, R & O and transmission fluids.

We have spoken to people that have had very good results with this product in hydraulic oil reservoirs. It immediately makes clear oils much more visible in sight glasses and on dipsticks.

These dyes are available from most CAT heavy-equipment dealers. CAT dealers are located all over the world. Please note that we do not sell CAT brand oil dye and have no affiliation with Caterpillar Inc.

Applications And Mixing Directions For CAT Oil Dye

Caterpillar Oil Dyes are available in the colors blue or red. They are soluble with most industrial hydraulic, compressor or gear oils where increased visibility is desired. It is best to consult your CAT dealer to ensure that the dye product is compatible with your intended application.

The recommended mix ratio is 16000:1. This means that 1 US ounce of dye will treat 125 US gallons of oil. The metric ratio is 6 milliliters of color to 100 liters of oil.

The Cat dye container size is 8 US ounces (240 ml). The entire container can treat 1000 US gallons (3785 liters) at the recommended mix rate.

Cat Oil Dye Part Numbers

Blue dye- New part number: 486-1536 (Old part number: 9U-5032)
Red dye- New part number: 486-1535 (Old part number: 9U-5031)

A Warning About Using Oil Dyes

Oil dyes are generally very concentrated. It is vital to wear gloves when handling oil dyes. Any contact with skin could lead to long-term staining.

In conclusion, oil dyes are an easy, safe and commonly found solution for clear industrial fluids.

AMSOIL Signature Series Max-Duty 5W-40 Synthetic Diesel OilA reader asks: I’ve got a 2018 GMC Sierra 2500 with the L5P Duramax diesel engine. I see that 15W-40 oil is suggested for this engine. Can I use 5W-40 in the winter?

Our answer: Yes, you can certainly use 5W-40 in winter (and summer) in your Duramax. While 15W-40 is suggested as the predominant viscosity for your engine, GM does recommend 5W-40 for temps below -18°C (0°F). AMSOIL’s official stance is that their 5W-40 synthetic diesel oils are safe and perfectly suited for year-round use under all conditions and loads. Naturally, 5W-40 is highly recommended for winter use, but there is absolutely no downside to using it in summer as well.

We offer two synthetic 5W-40 diesel motor oil options. The ultra-premium AMSOIL Signature Series Max-Duty 5W-40 and the value-priced AMSOIL Heavy-Duty Synthetic 5W-40.

Is There Any Advantage To Using 15W-40 Over 5W-40?

No. Remember that both 5W-40 and 15W-40 have a 40-weight viscosity. Note that both are offering roughly the same viscosity protection at operating temperature.

The main advantage that 5W-40 offers is faster oil flow during cold-starts.

It is true that 15W-40 has been the predominant diesel oil viscosity for decades. The reason that 15W-40 was a mainstay was its relatively slim spread between the winter weight (15W) and the operating temperature weight (“40”). With previous generations of motor oil technology, a wider spread between winter weight and operating weight (such as 5W-40) was more prone to shearing and thinning.

AMSOIL Heavy-Duty Synthetic 5W-40 Diesel Oil.Today’s motor oils (especially synthetic oils) have a much more linear viscosity across the temperature spectrum. As a result, they are much less prone to being too thick in the extreme cold or thinning out in extreme heat. Therefore, a good 5W-40 will provide flawless protection all year-round.

That is why a 5W-40 can now safely replace 15W-40 for year-round use.

What Is The Difference Between AMSOIL Signature Series Max-Duty and Heavy-Duty Diesel Oils?

Signature Series Max-Duty is AMSOIL’s most sophisticated formula. It delivers their absolute best wear control.

In the Detroit Diesel DD13 Engine Scuffing Test, Signature Series beat the minimum standard by 600%. Heavy-Duty Series beat the standard by 400%.

Signature Series Max-Duty is overbuilt for extended oil change interval capability. Heavy-Duty Series should be changed at the interval suggested by the manufacturer or by the oil life monitor.

Heavy Duty Series has a lower price tag. It was brought to market for commercial fleets, the installer market and value-minded consumers.

We can sell AMSOIL Signature Series Max-Duty and Heavy-Duty Series 5W-40 in Canada and the United States. Contact us using the form on this page for a wholesale price list.

AMSOIL Upper Cylinder LubricantAMSOIL has released a brand-new gasoline additive for cars and trucks. AMSOIL Upper Cylinder Lubricant is an inexpensive additive that has three key functions.

What Does AMSOIL Upper Cylinder Lubricant Do?

First of all, this product provides lubrication to the very top end of the cylinder. Tight tolerances in engines can prevent adequate amounts of motor oil from reaching the very top of the cylinder. This product delivers a shot of lubrication by way of the fuel. It also lubricates fuel injectors and pumps.

Second, as Upper Cylinder Lubricant contains detergents, it also keeps fuel injectors and combustion chambers clean. This maximizes fuel mileage and performance.

Third, Upper Cylinder Lubricant contains powerful anti-corrosion ingredients. Most of today’s regular and mid-grade gasoline has ethanol content. Ethanol attracts moisture. This can promote corrosion inside your engine. This product neutralizes moisture and provides an anti-corrosion coating on engine parts.

What Are The Applications For New Upper Cylinder Lubricant?

This product should be used in gasoline engines in automotive/light-truck applications only.

It is not suitable for diesel engines or 2-cycle motors. It is also not intended for use in small engines or recreational motors.

Doesn’t AMSOIL P.i. Performance Improver Already Provide These Features?

AMSOIL P.i. Gasoline Additive is a cleaner only. It does not provide the upper cylinder lubrication or the anti-corrosion features offered by Upper Cylinder Lubricant.

P.i. is an ultra-powerful fuel system cleaner that only has to be used every 4000 miles (6500 km). It is meant as a periodic cleaner or to clean exceptionally dirty fuel systems.

Upper Cylinder Lubricant is less than half the cost of P.i. It is an affordable product that can maintain fuel injector and combustion chamber cleanliness with every fill-up.

Great Choice For Gasoline Direct injection Engines

Gasoline direct injection (also known as “GDI”) engines are prone to severe combustion chamber and intake valve depositing. Regular use of AMSOIL Upper Cylinder Lubricant can prevent the formation of these carbon deposits. The occasional use of AMSOIL P.i. will also help to keep GDI engines very clean and running strong.

AMSOIL Vs. Lucas Vs. Sea Foam

AMSOIL commissioned independent testing to examine this product’s anti-wear properties. The testing compares AMSOIL versus Lucas Upper Cylinder Lubricant, Sea Foam Motor Treatment and straight regular gasoline. AMSOIL outscored Lucas by 18%, Sea Foam by 20% and stand-alone regular-grade gasoline by 21%.

AMSOIL 5W-30 Synthetic Small Engine OilAMSOIL has released a 100% Synthetic 5W-30 Small Engine Oil. This product is ideal for any utility or lawn/garden engine requiring a 5W-30 or straight-30 motor oil. This oil is suitable for small engines powered by gasoline, diesel, liquid propane or natural gas.

Why Did AMSOIL Make A 5W-30 Small Engine Oil?

This product joins 10W-30 and 10W-40 products in AMSOIL’s Small Engine Oil series.

Some small engine manufacturers (Honda comes to mind) suggest the use of a 5W-30 oil. Therefore, it makes sense for AMSOIL to have one in their line-up. With a cold-pour-point of -44°C (-47°F), this product is also the perfect oil for small engines that run in the winter.

Regardless of whether an engine is operated in extreme heat or cold, AMSOIL Synthetic 5W-30 Small Engine Oil will surely be a popular product.

How Is Small Engine Oil Different From Car Engine Oil?

Modern cars and light-trucks are equipped with all sorts of emissions sensors and devices. Some motor oil ingredients such as zinc can cause issues with these components. Therefore, modern automotive motor oils require a fairly sophisticated formulation approach. As small engines do not have emissions sensors and catalytic converters, AMSOIL is able to load this motor oil with anti-wear additives like zinc and phosphorus.

There is also another benefit to using this small engine oil over regular car motor oil. AMSOIL added significant anti-rust and corrosion ingredients that would not be found in automotive motor oils. Small engines are frequently stored for long periods. They may also be left outside or operate in wet conditions. This ability to prevent internal rust is a benefit to almost any small engine.

Highlights Of AMSOIL 5W-30 Synthetic Small Engine Oil

  • Suitable for a wide variety of small engines
  • Provides commercial-grade wear protection
  • Capable of staying in service for long intervals
  • Withstands extreme heat and heavy-loads
  • Delivers instant oil flow during winter start-ups
  • Resists oil consumption
  • Prevents deposit formation
  • Protects against internal corrosion during storage and operation in wet conditions
  • For small engines powered by gasoline, diesel, liquid propane and natural gas

Suitable Applications For AMSOIL 5W-30 Synthetic Small Engine Oil

  • Lawn and garden equipment
  • Snow blowers
  • Generators
  • Water pumps
  • Compactors
  • Mobile welders
  • Compressors
  • Pressures washers
  • Log-splitters
  • Masonry equipment
  • Skid-steers
  • Grain augers
  • And many more

Where Can I Buy AMSOIL 5W-30 Synthetic Small Engine Oil?

We can sell this new 5W-30 Small Engine Oil in Canada and the US. We have wholesale programs for individuals, commercial operators or retailers. Feel free to contact us for a price list using the form on this page.

AMSOIL Metric 15W-50 Synthetic Motorcycle OilA reader asks: I’ve got a Ducati Monster 1200. AMSOIL Metric 15W-50 Synthetic Motorcycle Oil is suggested for this model. This engine revs up to over 9000 rpm, so it needs oil with good wear protection and foaming resistance. What is the zinc and phosphorus content of this oil? I can’t find this information anywhere.

Our answer: The fixation on zinc and phosphorus content in motorcycle oil is old thinking. With today’s ashless additive technology, zinc and phosphorus levels are far less relevant for some motor oils. Let us explain.

AMSOIL Metric 15W-50 carries the JASO MA2 and API SM specifications. The JASO MA2 oil standard signifies that a motorcycle oil is safe for catalytic converters. High levels of traditional motor oil additives like zinc and phosphorus can damage catalytic converters. Therefore, alternate technology has to be employed in order for the oil to provide adequate wear protection.

Metric 15W-50 Synthetic Motorcycle Oil employs the latest “ashless” additive technology. Therefore, it has less zinc and phosphorus than some of AMSOIL’s more traditional motorcycle oil formulas.

Why Zinc And Phosphorus Numbers Are Not Important Anymore

Let’s compare the zinc and phosphorus content of AMSOIL V-Twin Synthetic 20W-50 and AMSOIL Metric Synthetic 15W-50. The V-Twin 20W-50 has a more traditional formulation than Metric 15W-50.

  • AMSOIL Metric 15W-50- Zinc- 841 ppm, Phosphorus- 767 ppm
  • AMSOIL V-Twin 20W-50- Zinc- 1300 ppm, Phosphorus- 1100 ppm

Based on these numbers, is the V-Twin 20W-50 vastly superior to Metric 15W-50? Not at all! AMSOIL Technical Services tells us that the wear control between the two products is identical. They also tell us that ashless additives bring other advantages.

For instance, when there is blow-by, old-style heavy-metal additives (such as zinc and phosphorus) from can create engine deposits. Ashless additives do not create these deposits.

Conclusion

Ashless motor oil additive technology has revolutionized motor oils in the passenger car and heavy-duty diesel engine oil segments. This technology is also a major player in part of the motorcycle oil market. Simply looking for the motorcycle oil with the highest zinc and phosphorus numbers won’t automatically point to the best product.
