Click here to check out the latest technical study and comparison of AMSOIL INTERCEPTOR® Synthetic 2-Stroke Oil and XPS-2 Synthetic 2-Cycle Oil and their ability to protect against engine wear and deposits. Direct fuel injection (DFI), sophisticated computer programming, targeted electronic oil injection and other developments have enabled a new era in two-stroke powersports engine design. Modern engines offer an unprecedented combination of increased power, improved fuel efficiency and reduced emissions. The increased level of performance comes at a price: Modern engines encounter increased heat, friction and stress while often using less oil to lubricate and protect vital engine parts. […]

Product focused – AMSOIL products are featured front-and-center with plenty of opportunities to “Buy Now” and “Learn More.” Multiple ways to shop – Consumers are offered the opportunity to browse by product category (motor oil, grease, etc.) or by equipment type (ATV, auto/light truck, etc.) and […]

The Petroleum Quality Institute of America (PQIA) has recently issued a number of consumer warnings regarding low-cost lubricants on the market that could damage engines and transmissions. PQIA issued an alert in January for Super XXX and Liberty Gold Plus SMO motor oils; an alert in December for Super Star, Royal Star, City Star and Royal lubricants; and an alert in November for City Star and Everclear automatic transmission fluids. Among the problems cited with the lubricants are very low viscosities, lack of additives and high silicon levels. AMSOIL has earned a reputation in the industry for manufacturing to more […]

AMSOIL products were promoting environmental sustainability long before it became fashionable. Today, AMSOIL’s environmental management system extends well beyond the products and has been registered to the ISO 14001:2004 standard.   In 1972, AMSOIL produced the first synthetic motor oil recommended for 25,000-mile/one-year drain intervals. It struck a blow against the wasteful practice of changing oil every 3,000 miles/three months. Today, many lubricant manufacturers have followed the AMSOIL lead and introduced extended-drain motor oils of their own, while original equipment manufacturers (OEM’s) now recommend drain intervals of up to 15,000 miles, and longer if using electronic oil life monitoring systems. […]

Reasons for Motor Oil Consumption AMSOIL Inc. issued Technical Service Bulletin (TSB) MO-2004-04-03 several years ago outlining reasons for motor oil consumption. Forty reasons are listed, two of which are oil-related, and the balance of issues are mechanical in nature. (The two oil-related reasons are “dirty oil” and overfilling the crankcase). It should be noted that a degree of consumption should be anticipated in all engines. What is considered normal oracceptable, however, will vary from one engine or application to the next. Some OEM’s (original equipment manufacturers) will not entertain oil consumption complaints from customers unless consumption is greater than one quart […]

The Functions of a Lubricant Modern motor oil is a highly specialized product carefully developed by engineers and chemists to perform many essential functions. A motor oil must: Permit easy starting Lubricate engine parts and prevent wear Reduce friction Protect against corrosion Keep engine parts clean Minimize combustion chamber deposits Cool engine parts (heat transfer properties) Seal combustion pressures Resist foaming (air bubbles do not lubricate and cause wear) Aid fuel economy Motor oil quality has changed dramatically in the past 30 years, and new demands on lubricants in modern engine designs call for oils that meet stringent requirements. Think […]

AMSOIL and Warranties The Magnuson-Moss Act is a U. S. federal law which states that a manufacturer may not require the use of a specific brand of aftermarket product, including lubricants, unless that part is provided by the manufacturer free of charge. (emphasis added). Misleading OEM Practices OEM’s often suggest in owner’s manuals, advertisements or through dealership personnel that motorists and enthusiasts must use the OEM-branded oil to comply with the new vehicle or equipment warranty. Some OEMs include warnings of catastrophic engine failure should a non-OEM oil be used. These tactics are especially pervasive in the powersports market and […]

A Comparative Study of SAE 5W-30 Synthetic Motor Oils Over many years, AMSOIL Inc. has been known in the industry as the “king of comparison.” One of the reasons for this is what many people know about motor oils is only what they read in an advertisement. As a result, AMSOIL has endeavored to educate consumers to the actual differences between lubricants, synthetic and conventional. Synthetic lubricants can provide benefits conventional oils cannot provide. In addition, all oils are not the same, even synthetics. All oils, synthetic or conventional, are not created equal. We believe that an educated consumer can make an informed decision. […]

 An Evaluation of AMSOIL Signature Series Multi-Vehicle Synthetic ATF and Signature Series Synthetic Motor Oil Operated under Severe-Service Conditions for Extended Drain Intervals Few applications place more stress on lubricants than taxi cabs, particularly those operating in the desert heat of Las Vegas, NV. The combination of excessive idling, stop-and-go driving and high ambient temperatures creates the ideal scenario for lubricant failure, resulting in sludge formation and catastrophic component failure. Fleet vehicles, heavy-duty pickups, work trucks and other commercial applications operate under severe service. In addition, drain intervals are getting longer. For engines and transmissions to last as designed and […]
