Extended Life XL
Amsoil Extended Life (XL) Motor Oils are formulated for up to 10,000-miles/six month intervals, or longer when recommended in owners’ manuals or indicated by oil monitoring systems. Provides better wear control, high- and low-temperature protection and increased fuel economy compared to conventional oils.
Original Equipment OEM
Amsoil OE Synthetic Motor Oil is specially formulated for the longer oil change intervals recommended by vehicle manufacturers today. Its advanced synthetic technology resists chemical breakdown for maximum wear protection (and peace of mind) well beyond the traditional 3,000-mile oil change interval.
AMSOIL Signature Series Synthetic Motor Oil is engineered to outperform conventional and synthetic motor oils.
