AMSOIL XLT 10W30 Synthetic Motor Oil is convenient and cost effective. They last longer than conventional petroleum motor oils, saving time and money. Motorists traveling 10,000 to 20,000 miles per year will find this product as a time saver. AMSOIL XL 10W-30 is now rated for 10,000 miles or 6-months which ever comes first using the oil filter of their choice.

This is the best choice for vehicles prone to engine sludge problems limiting the oil change interval. See the AMSOIL Technical Service Bullitin regarding this issue. "Using AMSOIL in engines with possible sludge issues"

AMSOIL Extended Life “XL 10W30” (XLT) Synthetic Motor Oils exceed the current performance requirements for gasoline engines and deliver exceptional performance by controlling wear and maximizing fuel economy.

AMSOIL Extended Life Synthetic Motor Oils provide peace of mind. The oil drain interval recommendations for many of today’s vehicles extend well beyond the traditional 3,000-mile interval, some up to 12,000 miles with electronic oil monitoring systems. And unlike petroleum oils that have 3,000-mile maximum recommendations, AMSOIL XL Oils provide 7,500-mile/six-month drain intervals or longer where stated by vehicle manufacturers or indicated by oil life monitoring systems. When using AMSOIL XL Synthetic Motor Oils, protection and performance are not sacrificed with longer drain intervals.

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.

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 vehicle.

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 10W30 Synthetic Motor Oil is fuel-efficient as it reduces friction-related energy loss. Expect better fuel economy compared to conventional, non-fuel-efficient motor oils. Customer feedback indicates competing brands rapidly cause a loss in mileage as they reach 5,000 to 7,000 miles. AMSOIL's XL line will remain in grade through the 10,000 mile guaranteed interval.

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 10W-30 Synthetic Motor Oil is engineered to resist sludge and carbon deposits better than conventional oils. Our 10W30 XL promotes clean operation for longer-lasting, better-running engines. Dispersants hold up to prevent further deposits at drain time.

Lower Fleet Maintenance Costs
Cost conscious business owners and fleet managers benefit from the extended drain intervals and wear protection of high quality AMSOIL XL Synthetic Motor Oils. While frequent oil changes are costly, time consuming and inconvenient, longer drain intervals reduce costs (labor, used oil disposal, facility demands) and improve environmental image. Fleet owners have made XL 10W-30 their product of choice to simplify maintenance while the life of the vehicle is extended too.

Bid Appropriate
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:

XLT 10W-30 Synthetic Motor Oil

  • API SN, SM...
  • ILSAC GF-5, GF-4...
  • ACEA A1/B1
  • GM 6094M
  • Chrysler MS-6395N

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.

In gasoline-fueled vehicles, AMSOIL XL Synthetic Motor Oils are 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.
