Amsoil Small Engine 4-Stroke 10W-40 Equipment Oil ASF

Engine dependability is vital to running a profitable business, yet most small-engine oils we’ve tested are nothing more than re-labeled automotive oils, which are formulated with fuel economy in mind, not durability. That won’t cut it. Compared to liquid-cooled automotive engines, small engines run hotter; operate under constant load; generate more oil-damaging contaminants; suffer from neglected maintenance; and are exposed to dirt, rain, snow and other extremes. Simply put, they’re far tougher on oil that most people think.

AMSOIL Synthetic Small-Engine Oil isn’t merely a re-badged automotive oil. Instead, we designed it from the ground up specifically for small-engine dependability. You can rest assured your engines are protected even during periods of extended use when there’s no time for scheduled maintenance. It’s built to solve the problems that plague small engines, including wear, power loss, oil consumption, harmful carbon deposits and stuck rings and valves. It helps landscapers, contractors and other professionals get more work done and save money

Excellent Wear Protection

AMSOIL Synthetic Small-Engine Oil is a shear-stable, high-film-strength formulation fortified with a heavy dose of anti-wear additives. It does not thin out due to mechanical shear, ensuring a thick lubricating film. It forms a durable barrier that protects against metal-to-metal contact.

Reduces Oil Consumption

In lab testing, AMSOIL 10W-30 Synthetic Small-Engine Oil reduced oil consumption 61 percent compared to three leading 10W-30/SAE 30 motor oils. Its heat-resistant synthetic base oils provide low volatility, excellent viscosity stability and strong oxidation resistance. Engines run longer between top-offs, providing peace of mind they won’t fail due to oil starvation and will run dependably in the harshest onditions.

Formulated for Power

Engine wear, carbon deposits, valve sticking and piston-ring sticking reduce engine power. AMSOIL Synthetic Small-Engine Oil prevents ring and valve sticking while helping eliminate carbon deposits from forming. As a result, engines produce maximum power throughout their service lives, helping you get more work done.

Extreme-Temperature Performance

AMSOIL Synthetic Small-Engine Oil’s saturated molecular structure offers outstand ing extreme-heat resistance. In addition, we’ve fortified the oil with potent antioxidant additives that provide further resistance to damaging heat. Its powerful detergent additives fight carbon, varnish and sludge to maximize engine life. In extreme cold, the oil’s naturally high viscosity index and lack of paraffins (waxes) ensure it remains fluid and flows quickly, providing easier cold-weather starts and fast startup lubrication for reduced wear.

AMSOIL Synthetic Lubricants

AMSOIL specialises in premium synthetic lubricants, filtration products and vehicle maintenance fluids for automotive, motorcycle, four-wheel drive, marine, racing and industrial applications. Founded in 1972 with the introduction of the first API-qualified synthetic motor oil, AMSOIL has continued to develop high-performance products designed to provide exceptional wear protection, resist heat and oxidation and maintain performance under demanding operating conditions. The AMSOIL range includes engine oils, transmission and gear lubricants, greases, fuel additives, filters and specialised fluids for enthusiasts who demand more from their vehicles and equipment.
