AMSOIL First in Synthetics and Best Motor Oil

Does motor oil expire? Yes, motor oil does go bad over time. The estimated shelf life for motor oil is 5 years when stored between 45ºF and 80ºF and at a temperature that does not fluctuate significantly. A sealed oil bottle is ideal for maximum shelf life. On the other hand, when motor oil is […]

Why use AMSOIL Synthetic Small Engine Oil? Protect your investment with 100% Synthetic oil that is specifically formulated to solve the problems that plague small engines, including wear, power loss, oil consumption, harmful carbon deposits, and stuck rings and valves. It helps homeowners, landscapers, contractors, and other professionals get more work done and save money.

9 Reasons to Make the Switch to AMSOIL Synthetic Small Engine Oil Shear-stable, high-film-strength formulation fortified with a heavy dose of zinc anti-wear additives. Does not thin out due to mechanical shear, ensuring a thick lubricating film for maximum wear protection. Zinc chemistry forms a durable barrier that protects against metal-to-metal contact. Reduced oil consumption

HIGH-TEMPERATURE / HIGH-SHEAR TEST (ASTM D5481) HIGH-TEMPERATURE / HIGH-SHEAR TEST (ASTM D5481) simulates shearing conditions at elevated temperatures.  The viscosity of the oil is measured at 302 F (150 ° C) under shearing forces, and results are reported in centipoise (cP).  The higher the test result, the greater the level of protection offered by the

NOACK VOLATILITY TEST (ASTM D5800) Simply put, lower oil volatility offers reduced oil burn-off and keeps valves clean. When comparing motor oils the industry maximum limit is 15%. When choosing an oil, the lower the Volatility percentage is better. NOACK VOLATILITY TEST (ASTM D5800) The most common method used in measuring oil volatility is the

CLEVELAND OPEN CUP TEST (ASTM D92) The Cleveland Open Cup Test (ASTM D92) measures flash and fire points of an oil. This test is intended for fluids having a flash point of 175 ° F (79.4 ° C) and above. A fixed volume of fluid is heated at a uniform rate while open to the

Pour Point Test Method While certain regions may never have to contend with extremely cold temperatures, it should be noted that lubricants with lower pour points may also aid in increased fuel economy, energy efficiency, and ease of starting. The most common method for determining the pour point of oil is the Standard Pour Point

Understanding Cold Crank Simulator Viscosity The COLD CRANK SIMULATOR (CCS) Viscosity Test is used to determine the internal fluid friction in motor oils with a “W” grade designation. This test is calculated in cP units as well, and measures the amount of energy required to overcome the resistance present in a lubricant that has been
