The AMSOIL Value Advantage


Consumers, now more than ever are seeking maximum value from the products they purchase. Since high quality products last longer and offer better performance, they generally provide better value advantages over the long term compared to their lower-priced counterparts. This is especially true when it comes to oils and lubricants. Customers who purchase lower-priced motor oils and practice 3,000-mile drain intervals do not receive maximum value.


AMSOIL Synthetic Motor Oils offer superior protection and performance for extended drain intervals providing value that cannot be matched. Whether you prefer shorter extended drain intervals or wish to take advantage of full length 25,000-mile/one-year intervals, AMSOIL offers products that achieve the most value for your money.

XL Value Advantage


If you prefer shorter extended drain intervals or a lower initial cost, AMSOIL offers its XL line of synthetic motor oils. AMSOIL XL Synthetic Motor Oils are API-certified, full synthetic motor oils with a recommended minimum drain interval of 7,500 miles or six months, whichever comes first. While they don’t provide the level of performance provided by the AMSOIL 25,000-mile oils, the XL line still easily trumps any petroleum-based motor oil as well as virtually all other synthetics on the market. In fact, when an oil life monitor is in use, AMSOIL XL Synthetic Motor Oils easily remain suitable for continued service far beyond the recommended 7,500 miles.


Although WIX Oil Filters are not designed to last the full length of a 25,000-mile oil drain interval, they offer excellent protection, performance and cost effectiveness for 7,500 miles and beyond when paired with AMSOIL XL Synthetic Motor Oils.

Signature Value Advantage


AMSOIL Signature Series 0W-30 Synthetic Motor Oil offers the longest drain interval in the AMSOIL product line, providing second-to-none protection and performance for up to 25,000 miles or one year, whichever comes first*. They remain on the forefront of lubrication technology. Advanced chemistries made from only the finest base oils and highest quality additive packages allow AMSOIL Synthetic Motor Oils to provide unsurpassed protection and performance.


AMSOIL Ea Oil Filters are the highest efficiency filters available to the auto/light truck market. Featuring advanced full synthetic nanofiber technology, Ea Oil Filters provide greater efficiency, capacity and durability than cellulose filters, extending engine and filter life and reducing engine wear. When combined with AMSOIL synthetic motor oils in gasoline and diesel vehicles, AMSOIL Ea Oil Filters are recommended for up to 25,000 miles or one year, whichever comes first. This is signature value.

Motorcycle Oil Value Advantage


AMSOIL Synthetic Motorcycle Oils are recommended for use up to twice (2X) the motorcycle manufacturer change interval (miles/hours) or one year, whichever comes first, in engines, transmissions and primary chain-cases. For Big Twin Harley-Davidson transmissions only, follow the Harley-Davidson recommended drain interval for synthetic oil of up to 20,000 miles or one year, whichever comes first.

When using an engine oil filter other than an AMSOIL Ea Motorcycle Oil Filter, change the filter at standard intervals. For off-road use, change AMSOIL at motorcycle manufacturer intervals. Racing or modified engines are excluded from extended drain interval recommendations. Oil changes are at the owner’s discretion.

Diesel Oil Value Advantage


AMSOIL Synthetic Diesel Oils are recommended for three times (3X) the OEM recommendation, not to exceed 50,000 miles/600 hours or one year, whichever comes first. Drain intervals may be extended further with oil analysis.


AMSOIL has documented fuel dilution issues in some 2007 and newer diesel engines. In some cases this has forced AMSOIL to adjust its drain interval recommendation in those applications to the manufacturer-recommended drain interval.
