Spring marks the time to store your snowblower and prepare your lawnmower, pressure washer, generator and other equipment for another season.
Make sure to change oil before storing equipment. Used oil contains acidic byproducts that can damage the engine if allowed to sit for months.
If you neglected to change oil in your lawnmower or other equipment prior to fall storage, now is a great time to do that.
Use a high-quality small-engine oil, not simply an inexpensive automotive oil
While easy to assume small equals simple when it comes to engines, the opposite is often true.
Compared to liquid-cooled automotive engines, air-cooled small engines run hotter; operate under constant load; generate more contaminants (with many not using a filter); and are exposed to mud, dirt and rain. Plus, they’re often overlooked when it comes to maintenance.
Most small-engine oils, however, are just re-labeled automotive oils, which are formulated with fuel economy in mind, not engine durability.
AMSOIL Synthetic Small-Engine Oil, in contrast, isn’t merely a re-labeled automotive oil – it’s designed specifically for the unique demands of small engines. It contains a heavy dose of zinc anti-wear additives to protect against wear for maximum power and engine life. It also contains potent detergency additives to fight harmful deposits.
Look at the bottom image of the valve-guide area in a Honda* 5-hp engine tested in the AMSOIL mechanical lab. A competitor’s oil resulted in heavy deposits that caused the valve to stick. In fact, the technician who tore down the engine couldn’t remove the valve due to excessive deposits. Had this engine been in the field, it would have been a matter of time before it failed, leading to a costly repair or replacement. AMSOIL 10W-30 Synthetic Small-Engine Oil, in contrast, minimized deposits and kept the engine running strong.

Motorcycle Oil for your Motorcycle? Ok, so it’s different but what makes AMSOIL better?
Motorcycle engines and automotive engines function differently, and the lubricants that service them have different requirements. Six crucial differences between motorcycle and automotive engines are outlined below to illustrate why oil engineered for motorcycles is the best choice for your bike.
Operational Speed: Motorcycles tend to operate at engine speeds significantly higher than automobiles. This places additional stress on engine components, increasing the need for wear protection, and subjects lubricating oils to higher loading and shear forces. Elevated operating rpm also promote foaming, which can reduce an oil’s load-carrying ability.
Compression Ratios: Motorcycles tend to operate with higher engine compression ratios than automobiles, which places additional stress on engine components and increases engine operating temperatures, placing greater demands on motorcycle oil to reduce wear. Higher operating temperatures also promote thermal degradation of the oil, reducing its life expectancy and accelerating the formation of engine deposits.
Horsepower/Displacement Density: Motorcycle engines typically produce more horsepower per cubic inch than automobile engines, which exposes the oil to higher temperatures and stress.
Variable Engine Cooling: In general, automotive applications use a sophisticated water-cooling system to control engine operating temperature. Similar systems can be found in motorcycle applications, but most are air-cooled or use a combination air/oil design. Operating temperatures in air-cooled bikes can skyrocket in stop-and-go traffic, promoting oxidation and causing oil to thin, reducing their load-carrying ability.
Multiple Lubrication Functionality: Many motorcycles have a common sump supplying oil to both the engine and transmission. In such cases, the oil is required to meet the needs of both the engine and the transmission gears. Many motorcycles also incorporate a wet clutch within the transmission that uses the same oil.
Inactivity: Whereas automobiles are used on a daily basis, motorcycle use is usually periodic and, in many cases, seasonal. These extended periods of inactivity place additional stress on motorcycle oils. In these circumstances, rust and acid corrosion protection are of critical concern.
No matter the conditions or the bike, AMSOIL synthetic motorcycle oils deliver the premium protection and performance your bike deserves. They are designed to control oxidation and maintain viscosity at higher temperatures, promote consistent clutch feel and lengthen clutch life, reduce engine stress and control wear and deposits in high-compression, high-temperatures motorcycle applications. V-twin or metric, AMSOIL has you covered.
Now for the Extreme test!! Hold on to your hat for this one, I was so impressed by this I thought I would grab the text from this AMSOIL brochure. So glad AMSOIL added this whole testing wing to the AMSOIL Center with bays capable of doing multiple tests at once. Watch the video which demonstrates the test laid out within the paragraphs.
V-Twins Get Hot
Harley-Davidsons* and other bikes with big V-twin engines generate significant heat, especially in low-speed parades, in rally traffic or on long climbs on hot days. Motor oil plays a critical role in cooling these big air-cooled engines, and even more so in low-speed operation with limited wind generated to cool the bike. If the oil can’t withstand the heat, its ability to protect your bike is compromised.
AMSOIL Synthetic Motorcycle Oil Protects in Extreme Heat
To demonstrate its extreme-heat protection qualities, AMSOIL 20W-50 Synthetic Motorcycle Oil was subjected to a dynamometer test designed to simulate conditions even more extreme than the demanding stop-and-go driving conditions of a motorcycle rally or parade route.
A 2012 Harley-Davidson FXDB Dyna Street Bob* motorcycle equipped with AMSOIL 20W-50 Synthetic Motorcycle Oil was subjected to a strenuous low-speed test cycle, with significant idle time broken by short bursts of engine revving and little to no air moving across the cylinders. Like most Harley-Davidson motorcycles, the Dyna Street Bob features an air-cooled V-twin engine, which relies on cooling fins arrayed along the cylinder walls to conduct heat away. To create the most-severe operating conditions possible, the electronic temperature controls, which safeguard the motorcycle when temperatures reach dangerous levels, were deactivated. The combination of low airflow and inoperative temperature controls allowed the test lab to subject the oil and engine components to intense heat not normally experienced in the real world. Cylinder temperatures reached more than 500°F, and oil temperatures exceeded 300°F – temperatures well into the range where oils begin to break down and often lead to catastrophic failure.
500°F is No Problem The extreme temperatures were no match for AMSOIL Synthetic Motorcycle Oil. After nearly 70 minutes of torturous testing and heat exposure, oil analysis revealed no change in oil viscosity and only minor levels of oxidation, TBN depletion and wear (see graphs).
Dyno Test Results
Not only did AMSOIL Synthetic Motorcycle Oil prevent the engine from overheating and seizing during the extreme dyno test, it did so without losing chemical integrity or ability to protect vulnerable engine components. This stands as further proof that AMSOIL Synthetic Motorcycle Oil provides outstanding protection in even the most compromising and severe high-temperature riding and idling conditions, providing peace of mind that your air-cooled V-twin is protected even in low speeds on hot days. Your bike should never get this hot. If it does, AMSOIL has you covered.
