Data Bulletin 

AMSOIL XL 10W-30 (XLT) Extended Life Synthetic Motor Oil is designed to provide better wear control, improved high- and low-temperature protection and increased fuel economy compared to conventional oils. Amsoil XL 10W-30 (XLT) Synthetic Motor Oil is formulated with extended-drain boost technology. It provides superior performance for up to 10,000-miles/six months, or longer when recommended in owners’ 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. Amsoil XL 10W-30 (XLT) 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.

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 10W-30 (XLT) 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.

Bid Appropriate

Amsoil XL 10W-30 (XLT) 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 10W-30 (XLT) 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:

XLT 10W-30: API SN (Resource Conserving), SM…; ILSAC GF-5, GF-4…; ACEA A1/B1; GM 6094M, 4718M; Chrysler MS-6395


Amsoil XL 10W-30 (XLT) Synthetic Motor Oil is compatible with conventional and other synthetic motor oils. Mixing Amsoil XL 10W-30 (XLT) 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 10W-30 (XLT) Synthetic Motor Oil.


In gasoline-fueled vehicles, Amsoil XL 10W-30 (XLT) 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.
