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

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

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)

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

Most mobile and stationary hydraulic applications do not require the extreme temperature performance properties provided by AMSOIL Synthetic AW Series Hydraulic Oils, and the new HV Series Synthetic Multi-Viscosity Hydraulic Oils now provide a more cost-effective, high performance alternative to conventional hydraulic oils. AMSOIL Synthetic HV Series Multi-Viscosity Hydraulic Oils are engineered to outperform any oil found in the general hydraulics market. They have very high viscosity indices that far exceed conventional oils. They provide all-season capability and are designed to significantly reduce

AMSOIL HP Injector Synthetic 2-Cycle Oil is now AMSOIL HP Marine™ Synthetic 2-Stroke Oil. AMSOIL HP Marine™ Synthetic 2-Stroke Oil is the high-performance marine 2-stroke oil. AMSOIL HP Marine™ is formulated with MAXDOSE™, a system of advanced additives for "super-clean" operation. It helps prevent deposits that lead to poor performance. In field testing, HP Marine™ inhibited ring deposits that can cause ring sticking and ring jacking (carbon build-up behind the ring, forcing it outward), a phenomenon that occurs in modern DFI

Now - AMSOIL Ea® Heavy-Duty Extended-Life Oil Filters! AMSOIL has expanded the Ea® Oil Filter product line to provide extended service intervals that coincide with the maximum drain intervals of AMSOIL Synthetic Motor Oils for on- and off-road heavy equipment. AMSOIL EaHD Oil Filters are engineered to provide excellent efficiency and capacity throughout extended-service intervals. They are rated at 20 microns absolute, which ranks them among the most efficient oil filters available for heavy-duty applications. AMSOIL EaHD Oil Filters should be
