Product Description

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.

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 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.

MIXING AMSOIL

AMSOIL XL Synthetic Motor Oils are compatible with conventional and other synthetic motor oils. Mixing AMSOIL XL Synthetic Motor Oils with other oils, 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.

HEALTH & SAFETY

This product is not expected to cause health concerns when used for the intended application and according to the recommendations in the Material Safety Data Sheet (MSDS).

Will always use this product!

Use this in my old Chevy 454 powered motorhome. This motor really works hard and gets Hot. Oil pressure stays up on hottest days and no leaks or oil burning. It's the best protection for my motor that
I can find.

The only lubricant products.

Amsoil has been the only choice in lubricants since 1985, what else needs saying? Multiple BMW motorcycles, my wife's 2000 F150 with many miles, a couple of Suzuki Sidekicks, both high mileage with routine maintenance only. Enough to convince even those with little automotive knowledge.

Happy, happy, happy

This was purchased for a co-worker. He spoke to me about using the products and I explain how there was no better in the market. He is very happy and I feel will be returning for all his lubricate needs.

I will always use AMS oil

I am 71 years old in my second childhood. I have used every kind of oil in my life time. I personally will never use any other oil in my special car other than AMS. I bought a 2013 SI Honda Civic and I put a supercharger, different exhaust and had it dyno tuned and much more. Results over 300 HP to the wheel. I fell safe using this oil up to 6000 miles but I change at 30% not 15%. If you use this oil in your car you will never change to any other. I guarantee that.
