If your ATV or Side by Side sees a lot of water crossings or mud bogs, we have a few products that can protect important components from water damage. Using a gear lube, grease, fuel additive and engine oil that are designed to neutralize the effects of moisture exposure can go a long way toward averting nasty repair bills.

Water Resistant Gear Lube for ATV Differentials

AMSOIL Universal Synthetic Marine 75W/80W-90 Gear Lube Whether your ATV’s differentials call for an SAE 80, 80W-90 or 75W-90, we have a gear lube that can cover all of those viscosities and withstand up to 10% water contamination. AMSOIL Universal Synthetic Marine 75W/80W-90 Gear Lube is suitable for applications requiring an API GL-4 or GL-5 product. Why use a marine gear lube in an ATV? This gear lube has same the extreme pressure (EP) additive content and protective abilities of gear lubes designed for dry land, but it is specifically formulated to withstand water contamination. Water can compromise a gear lube’s extreme pressure properties and promote foaming which can quickly lead to metal-to-metal contact. AMSOIL Universal Synthetic Marine Gear Lube not only reduces the risk of water damage, the synthetic formula delivers all-climate wear control of gears and bearings and also conditions seals to prevent leaks.

Water Resistant Grease for ATV’s

AMSOIL Synthetic Water Resistant GreaseIf your ATV has serviceable grease fittings on u-joints or suspension pivots, AMSOIL Synthetic Water Resistant Grease is our foremost grease recommendation, even if your machine rarely takes a dip. The sophisticated synthetic formula is fortified with extreme pressure additives and is suitable for general chassis, u-joint or wheel bearing service. When the going gets soggy, this grease resists water spray-off, complete submersion, mud, snow and ice. This grease stays put, no matter what you throw at it. For that reason we can’t imagine a better grease for ATV, snowmobile, marine or general-use around your yard.

Fuel Additive for ATV’s

AMSOIL Quickshot Fuel AdditiveGetting water in a differential or suspension pivot will cause problems over time, but getting moisture in your fuel can stop you in your tracks. While it’s unlikely that water can enter your fuel tank during a trail ride, you can’t always be sure about fuel sources along the way. The ethanol content of gasoline absorbs moisture and can cause a severe lean condition when it makes its way into the combustion chamber. It can also cause gumming and depositing. AMSOIL Quickshot Powersport Fuel Additive neutralizes moisture in fuel, allowing it to pass harmlessly through the engine. Quickshot also cleans out existing carb or injector deposits as well as those in the combustion chamber. It even stabilizes gasoline between rides. Quickshot is highly beneficial in any small engine or gasoline-powered toy.


ATV Engine Oil

AMSOIL Formula 4-Stroke 0W-40 Synthetic Motor OilIf moisture makes it’s way into your engine, rust and corrosion can form over time. AMSOIL Synthetic ATV & Motorcycle Oils borrow anti-corrosion additive technology from their marine engine oils to protect engine internals from corrosion damage between rides and during long-term storage. AMSOIL Synthetic ATV Oils also offer benefits such as lower friction, reduced wear, cooler operation and improved start-up protection in any climate. Available in 0W-40, 10W-30, 10W-40, 20W-50 and SAE 60.

Which choice is better for Harley-Davidson transmissions?

A particularly nice feature about AMSOIL 20W-50 Synthetic Motorcycle Oil is that it can be used in the engine, transmission and primary chaincase of Harley-Davidson motorcycles. But some riders wonder if a gear lube like AMSOIL Severe Gear Synthetic 75W-110 or 75W-140 is a better choice. Let’s explore this question.

AMSOIL Synthetic 20W-50 Motorcycle OilFor Evolution 1340 and all Twin Cam engines, AMSOIL’s first recommendation for the engine, transmission and primary chaincase is AMSOIL 20W-50 Motorcycle Oil. For the transmission of these models, they offer a secondary recommendation of AMSOIL Severe Gear 75W-110 and a third option being Severe Gear 75W-140. Some riders claim to experience quieter operation with these options, but are there real world benefits?

First, let’s establish that AMSOIL 20W-50 Synthetic Motorcycle Oil is fortified with anti-wear additives to deliver maximum gear wear control. It is also formulated to resist shearing for long service life. The Severe Gear Lubes will work just fine, but will not offer improved wear control over the 20W-50 motorcycle oil.

Let’s point out that the AMSOIL Motorcycle 20W-50 and Severe Gear 75W-110 are identical in terms of thickness at operating temperature. Gear lubes use a different viscosity grade scale on the label to prevent confusion between gear lubes and motor oils. Here is the kinematic viscosity of each product at 100 degrees centigrade as shown in centistokes (cST).

20W-50 Motorcycle- 20.4 cST
75W-110 Severe Gear-  20.3 cST
75W-140 Severe Gear- 27.5 cST

So will a thicker oil offer better protection in Harley transmissions?

No that is not the case. The Severe Gear 75W-140 may offer quieter operation simply because of the thicker viscosity. It doesn’t necessarily mean that better wear control is the result. In fact a thicker oil could potentially result in slightly higher operating temperatures.

Bottom Line

AMSOIL 20W-50 Synthetic Motorcycle Oil aces the FZG Gear Test with a perfect score of “zero” wear and again, is loaded with anti-wear additives to deliver the ultimate in wear prevention. It is also formulated to limit friction for optimum shifting performance.  If you wish to use one of the Severe Gear products, that is no problem. The bottom line is that there is no appreciable advantage to using them over the 20W-50. The convenience of using the 20W-50 in all three holes trumps any perceived advantage in our opinion.

There is a brand new class of off-road vehicle about to hit the market and it is creating quite a stir. It looks one part Segway and one part Abrams tank and is the most fascinating toy we’ve seen in a ages. This innovation is called the DTV Shredder and it is the brainchild of Canadian start-up BPG Werks. DTV stands for “dual tracked vehicle”.

DTV Shredder from BPG Werks

The DTV Shredder from BPG Werks

Basically you stand on the Shredder and use the hand throttle to go forward. To turn the unit, you lean as though you were on a skateboard. A patented CVT transmission changes the speed of the tracks as you lean. It is powered by a Lifan 196cc four-stroke engine that produces about 13 horsepower and generates a top speed of around 30MPH. As you’ll see in the video, the Shredder can traverse virtually any type of terrain. Rocks, sand, snow, water crossings (up to 10” deep), fallen logs and steep grades are child’s play to this track-driven wonder. The handle bar assembly folds down for easy transport and storage.

BPG Werks also has a military version is the works which is a battery/gas engine hybrid with extensive unmanned, remote controlled capabilities.

BPG Werks is about to ship their backlog of initial orders. Base units retail for $4000 (US). The Shredder will soon be available through their dealer network and can also be purchased online for home delivery.

We have a feeling that the Shredder is going to be more that a passing fad and this could very well be the dawn of a new powersport category.

AMSOIL’s Synthetic Automatic Transmission Fluid products are in the news. They are receiving a name change, AMSOIL has released some third-party test results and the specification list has been updated.

AMSOIL Synthetic ATF Name Change

Both the Multi-Vehicle ATF and Fuel Efficient ATF have been rolled into the Signature Series family. They are now called Signature Series Multi-Vehicle Synthetic ATF and Signature Series Fuel Efficient Synthetic ATF. The Signature Series moniker is given only to AMSOIL’s best, so this change emphasizes the elite quality of these two products. Along with the new names, come new labels and a new look. The formulations are unchanged.

Independent, Third-Party ATF Testing

AMSOIL commissioned independent testing on the Signature Series Multi-Vehicle Synthetic ATF under real-world conditions. The ATF was put through the its paces in Las Vegas taxi cabs. As you can imagine, Las Vegas cabs endure continuous stop-and-go conditions in extreme desert heat.

After 100,000 miles of taxi service, used AMSOIL Synthetic ATF samples were tested using the Aluminum Beaker Oxidation Test (ABOT). This test determines an ATF’s ability to resist oxidation. To meet the Chrysler ATF+4 specification, a new fluid must be able to resist oxidation after 500 hours of ABOT testing. As seen in the chart below, the AMSOIL Signature Series Multi-Vehicle Synthetic ATF that had been USED for 100,000 miles in a Las Vegas cab not only passed the ABOT test at 500 hours, but had another 300 hours in reserve over and above that threshold!

AMSOIL ATF TAN Reserve Protection Graph

Suffice it to say, AMSOIL Synthetic ATF’s are engineered to protect your automatic transmission from extreme heat, heavy towing and harsh conditions. A transmission oil change is performed infrequently, so why not use a fluid that will perform and protect with no compromises?
