AMSOIL Synthetic Motor Oils Provide Maximum Protection

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

By offering maximum protection and performance for extended drain intervals, AMSOIL synthetic motor oils provide value like no other motor oil can. Whether a customer prefers shorter extended drain intervals or wishes to take advantage of full length 25,000-mile/one-year intervals, AMSOIL offers a value package that helps them receive the most for their money.

Value Package I

For customers who 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 or oil analysis is employed, AMSOIL XL Synthetic Motor Oils easily remain suitable for continued service far beyond the recommended 7,500 miles.

While 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.

Value Package II

AMSOIL extended drain synthetic motor oils 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 for up to 25,000 miles or one year, whichever comes first.*

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 35,000 miles or one year, whichever comes first.*

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 used in conjunction 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. That's value.

Value Package III - Diesel

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.

For complete, updated AMSOIL diesel oil drain recommendations for 2007 and newer diesel engines, see the Revised Diesel Oil Drain Interval Recommendations.

Value Package IV - Motorcycle

AMSOIL Synthetic Motorcycle Oils are recommended for use up to twice the motorcycle manufacturer change interval (miles/hours) or one year, whichever comes first, in engines, transmissions and primary chaincases. 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 filter other than 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.

*See the AMSOIL Product Information and Drain Interval Chart for specific drain interval recommendations based on product and driving style.

Premium AMSOIL Synthetic Motor Oils offer the longest drain intervals on the market, unsurpassed protection and performance that effectively extends equipment life and improved fuel economy, saving customers money at the pump and reducing the nation's dependence on foreign oil.


"AMSOIL INC. warrants that the use of its lubricants will not cause mechanical damage to any mechanically sound equipment when AMSOIL INC. products are used in full compliance with the company's recommendations and instructions."


FULL WARRANTY


AMSOIL synthetic motor oils are formulated to surpass engine test specifications, offering protection far greater than competing motor oils for extended drain intervals. Most synthetic oil manufacturers make no claim to extended drain intervals, deferring to the maintenance schedule provided by the vehicle manufacturer. With its unparalleled oil and warranty program, AMSOIL offers consumers unprecedented protection and economics.


Another AMSOIL First

More than 20 years ago, AMSOIL began using the NOACK volatility test as a comparison tool and measurement of quality. Back then, nearly every oil tested side-by-side with AMSOIL synthetic motor oils failed, and those that passed barely squeaked by. Other oil companies paid no attention to NOACK results until Ford Motor Company made it a requirement for service fill oils, validating what AMSOIL had said all along.


THE NOACK Volatility Test
The NOACK Volatility Test determines the evaporation loss of lubricants in high temperature service. The more motor oils vaporize, the thicker and heavier they become, contributing to poor circulation, reduced fuel economy and increased oil consumption, wear and emissions. AMSOIL Synthetic Motor Oil resists high temperature volatization better than other motor oils. AMSOIL Synthetic Motor Oil maintains peak fuel efficiency and reduces oil consumption and emissions.

AMSOIL Now An ISO Certified Manufacturer
AMSOIL recently received ISO 9001:2000 certification of our Quality Management System (QMS). NSF International Strategic Registrations is the registrar that has verified our QMS meets the requirements of the ISO 9001:2000 standard, the most widely utilized quality standard throughout the world for quality management systems.
