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. AMSOIL XL Synthetic Motor Oil is formulated with extended-drain boost technology. It employs 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.
Lowers Maintenance Costs
Cost-conscious motorists, business owners and fleet managers benefit from the extended drain intervals and wear protection of AMSOIL XL Synthetic Motor Oil. Frequent oil changes are expensive, time-consuming and inconvenient, while longer drain intervals reduce costs and environmental impact. Increased wear control can further reduce maintenance costs. With AMSOIL XL Synthetic Motor Oil, motorists realize the convenience and cost savings of extended drain intervals with excellent engine protection.
Improves Fuel Economy
XL Synthetic Motor Oil is formulated with friction modifiers to reduce friction-related energy loss. It excels in fuel-economy testing, earning the “Resource Conserving” designation from the API.
Maintains Low Emissions
AMSOIL XL Synthetic Motor Oil is friendly toward modern emissions control systems, promoting proper operation of catalytic converters for optimum service life and low exhaust emissions.
Protects in All Temperatures
AMSOIL XL is a multi-viscosity formulation. It resists the effects of thermal breakdown, including evaporation and viscosity loss, while remaining fluid in cold temperatures for easy cold starts and fast startup circulation.
Keeps Engines Clean
AMSOIL XL Synthetic Motor Oil is fortified with detergent and dispersant additives. It is engineered to resist sludge and carbon deposits better than conventional oils. It promotes clean operation for longer-lasting, better-running engines.
AMSOIL XL Synthetic Motor Oil fulfills the requirements of most public and private purchasing bids. It is cost-effective, making it ideal where synthetic motor oil is specified.
AMSOIL XL Synthetic Motor Oil is excellent for use in gasoline-fueled vehicles. It is recommended for all domestic and foreign vehicles requiring any of the following specifications:
- API SN, SM…; ACEA A1/B1
AMSOIL XL Synthetic Motor Oil is compatible with conventional and other synthetic motor oils. Mixing AMSOIL XL Synthetic Motor Oil with other oils, however, will shorten the oil’s 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 Oil.
In gasoline-fueled vehicles, AMSOIL XL Synthetic Motor Oil is recommended for up to 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.
