What’s the Best Oil for My Snowblower?

In the event of a snowstorm, it's crucial for your snowblower to start up and assist you in completing the task at hand. However, snowblower engines encounter distinctive challenges that may compromise their reliability, horsepower, and overall lifespan. Thankfully, there are maintenance techniques available that can significantly enhance dependability. One such practice involves the use of a specially formulated small-engine oil.

Despite being used less frequently than other engines, snowblower engines impose greater demands on oil than commonly recognized. In comparison to liquid-cooled automotive engines, small engines typically lack oil filters, endure higher operating temperatures, consistently handle heavy loads, produce more contaminants harmful to oil, and are exposed to challenging elements such as snow, water, and extreme temperatures.

Snowblower engines are often stored in unheated garages or sheds, where cold temperatures impede the oil's flow during startup—a significant contributor to engine wear. Employing a high-quality, purpose-built oil can offer additional safeguards for your snowblower's engine, mitigating the risk of component damage and extending its operational life.

Regrettably, many small-engine oils we've assessed appear to be merely rebranded automotive oils, primarily designed to enhance fuel economy rather than withstand the harsh operating conditions unique to snowblower engines.

AMSOIL's 100% Synthetic Small-Engine Oil is not merely a repackaged automotive oil; rather, it is meticulously crafted from scratch to cater specifically to the demands of small engines. Our formulation is designed to address common issues afflicting small engines, such as wear, power loss, oil consumption, the accumulation of harmful carbon deposits, and the occurrence of stuck rings and valves.

AMSOIL's Synthetic Small-Engine Oil is a robust formulation with excellent shear stability and high film strength, bolstered by a substantial concentration of anti-wear additives. It maintains its viscosity even under mechanical shear, guaranteeing a persistent, thick lubricating film. This results in the creation of a resilient barrier that effectively shields against metal-to-metal contact.

The decline in engine power caused by factors like engine wear, carbon deposits, valve sticking, and piston-ring sticking is a common issue. AMSOIL Synthetic Small-Engine Oil is engineered to counteract ring and valve sticking, actively working to prevent the formation of carbon deposits. Consequently, engines experience sustained maximum power throughout their operational lifespan, enabling more efficient snow removal.

AMSOIL's 100% Synthetic Small-Engine Oil features a saturated molecular structure, providing exceptional resistance to extreme heat. Furthermore, we have enhanced the oil with potent antioxidant additives to reinforce its resilience against damaging high temperatures. The oil's robust detergent additives actively combat carbon, varnish, and sludge, thereby maximizing the engine's operational life.

Even in extremely cold conditions, the oil's naturally high viscosity index and absence of paraffins (waxes) ensure its fluidity and rapid flow, facilitating easier cold-weather starts and swift startup lubrication that reduces wear.
