AMSOIL Extended Life “XL” Synthetic Motor Oils exceed the current performance requirements for
gasoline engines and deliver exceptional performance by controlling wear and maximizing fuel economy.
AMSOIL XL Synthetic Motor Oils are convenient and cost effective. They last longer than
conventional petroleum motor oils, saving time and money. Motorists traveling 15,000 miles per year need only
change AMSOIL XL motor oils twice, compared to five times for conventional 3,000-mile change intervals. While the
initial fill may be more expensive than conventional oil, mile for mile AMSOIL XL costs less.
AMSOIL Extended Life Synthetic Motor Oils provide peace of mind. The oil drain interval
recommendations for many of today’s vehicles extend well beyond the traditional 3,000-mile interval, some up to
12,000 miles with electronic oil monitoring systems. And unlike petroleum oils that have 3,000-mile maximum
recommendations, AMSOIL XL Oils provide 7,500-mile/six-month drain intervals or longer where stated by vehicle
manufacturers or indicated by oil life monitoring systems. When using AMSOIL XL Synthetic Motor Oils, protection
and performance are not sacrificed with longer drain intervals.
AMSOIL, the leader in automotive synthetic lubrication, produced the world’s first API qualified
synthetic motor oil in 1972. Trust the extensive experience of AMSOIL, The First in Synthetics®, to do the best job
protecting your vehicle.
