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 rigorous standards than other lubricant companies. The process begins by selecting raw materials based on quality and performance, not price. AMSOIL quarantines and tests all incoming raw material to ensure it meets the company's strict performance standards before accepting it for use. Every product AMSOIL manufactures is tested every time it is blended to ensure maximum quality and consistency. This ensures AMSOIL users receive the same high performance every time they purchase AMSOIL synthetic lubricants.
