AMSOIL Extended Life 10W-40 Synthetic Motor Oil (XLO)

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 systems.



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 engine.

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.

Bid Appropriate

AMSOIL Extended Life XL Synthetic Motor Oils fulfill the requirements of most public and private purchasing bids. These oils are cost effective, making them ideal where synthetic motor oil is specified.

Applications

AMSOIL Extended Life 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:

• API SN, SM...
• ACEA A1/B1

Mixing AMSOIL

AMSOIL XL Synthetic Motor Oils are compatible with conventional and other synthetic motor oils. Mixing AMSOIL XL Synthetic Motor Oils with any other oil, however, will shorten the oil life expectancy and reduce the performance benefits. AMSOIL does not support extended drain intervals where oils have been mixed. Aftermarket oil additives are not recommended for use with AMSOIL XL Synthetic Motor Oils.

SERVICE LIFE

In gasoline-fueled vehicles, AMSOIL XL Synthetic Motor Oils are recommended for up tp 10,000-mile/six-month oil change intervals or longer when recommended in owner's manuals or indicated by electronic oil life monitoring systems. Change aftermarket, original equipment manufacturer or AMSOIL Ea Oil Filter at every oil change.
