Great for any vehicle, the XL series by AMSOIL is one of the top sellers in our Sioux Falls store. While we suggest the Signature Series for you highest performance vehicle the XL is a perfect choice for an older car with high mileage. Vehicles which the owner may have been reluctant to try or switch to a synthetic – now there is No Excuse!! AMSOIL’s XL exceeds the performance and quality of competitor brands (we know this because new customers can tell there’s an improvement in the way the car runs and feels.) and is backed by their legendary warranty.  The additive package is designed to deal with sludge, deposits, old seals, hot-spots, extreme variations in temperature and the ability to hold it’s viscosity over the stated 10,000 mile interval or 6-months. The perfect twice per year oil change!

For some the XL line’s greatest feature is the price! Call the Sioux Falls store for the retail pricing, case pricing and our discount program pricing. Call 402-933-3902. Commercial and retail establishments which wish to use AMSOIL products within their fleet or resale AMSOIL products in their shops will find this is a great asset to their bottom line or customer base. Special pricing for those accounts too.

AMSOIL XL (Extended Life) is also perfect for those who depend on their “Oil change by the dash” indicator. Because these indicators may sometimes run on for longer than traditional change intervals the XL is fully able to last as long as some which can go as far as 14,000 miles or a year. (See service life below)

Extended Life 5W-30 Synthetic Motor Oil for 10,000 miles

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 5W-30 Synthetic Motor Oil, motorists realize the convenience and cost savings of extended drain intervals with maximum engine protection.

Improves Fuel Economy
XL Synthetic Motor Oil is formulated with friction modifiers to reduce friction-related energy loss. It provides better fuel economy compared to conventional, non-fuel-efficient motor oils.

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, better than conventional oils while remaining fluid in cold temperatures for easier 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.

Bid Appropriate
AMSOIL XL 5W-30 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 all types of gasoline-fueled vehicles. It is recommended for all domestic and foreign vehicles requiring any of the following specifications:

XLF 5W-30

AMSOIL XL 5W-30 Synthetic Motor Oill 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.
