AMSOIL XL Extended Life Synthetic Motor Oils provide better wear control, high-
and low-temperature protection and increased fuel economy compared to conventional
oils. Formulated with extended-drain boost technology, AMSOIL XL Synthetic Motor
Oils provide superior performance for up to 10,000-miles/six months, or longer when
recommended in owner’s manuals or indicated by electronic oil life monitoring
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
Extended-Drain Boost Technology
During normal engine operation, the combustion process creates acidic by-products
that can lead to internal component corrosion and a reduction in the life
expectancy of the engine oil and engine itself. Formulated with extended-drain
boost technology, AMSOIL XL Synthetic Motor Oils employ high-quality synthetic base
stocks and a unique additive chemistry to neutralize acids longer than conventional
oils. The extra additive package effectively raises the Total Base Number (TBN), a
measure of an oil’s useful service life, and provides superior protection and
performance throughout the entire drain interval.
Lower Maintenance Costs
Cost-conscious motorists, business owners and fleet managers benefit from the
extended drain intervals and wear protection of AMSOIL XL Synthetic Motor Oils.
While frequent oil changes are expensive, time consuming and inconvenient, longer
drain intervals reduce costs and environmental impact, while increased wear control
can reduce maintenance costs. With AMSOIL XL Synthetic Motor Oils, motorists
realize the convenience and cost savings of extended drain intervals while also
providing vehicles with maximum protection.
Improve Fuel Economy
Formulated with friction modifiers, AMSOIL XL Synthetic Motor Oils are
fuel-efficient oils that reduce friction-related energy loss. They provide better
fuel economy compared to conventional, non-fuel-efficient motor oils.
Maintain Low Emissions
AMSOIL XL Synthetic Motor Oils are friendly toward modern emissions control
systems, promoting proper operation of catalytic converters for optimum service
life and low exhaust emissions.
Hot- and Cold-Engine Protection
AMSOIL XL Synthetic Motor Oils are multi-viscosity formulations. Compared to
conventional oils, they better resist the effects of thermal breakdown, including
evaporation and viscosity loss, while remaining fluid in cold temperatures for
easier cold starts and fast start-up circulation.
Keep Engines Clean
Fortified with detergent and dispersant additives, AMSOIL XL Synthetic Motor Oils
are engineered to resist sludge and carbon deposits better than conventional oils.
They promote clean operation for longer-lasting, better-running engines.
AMSOIL XL Synthetic Motor Oils fulfill the requirements of most public and private
purchasing bids. They are cost effective, making them ideal where synthetic motor
oil is specified.
AMSOIL XL Synthetic Motor Oils are excellent for use in all types of
gasoline-fueled vehicles. They are recommended for all domestic and foreign
vehicles requiring any of the listed performance specifications:
