XL 5W-30 Synthetic Motor Oil

Omaha’s #1 best selling AMSOIL Product

Great for any vehicle, the XL series by AMSOIL is one of the top sellers in our Omaha store. While we suggest the Signature Series for you highest performance vehicle the XL really now has become our best value for all vehicles. 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 boosted to deal with sludge, deposits, old seals, hot-spots, extreme variations in temperature and the ability to hold it’s viscosity over the 12,000 mile or 1-year period.

For some the XL line’s greatest feature is the price! It was created to make the highest quality product within a reasonable and acceptable price level for non-automotive enthusiasts.

Call the Omaha 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.MSOIL 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.

AMSOIL XL is available at the Omaha Synthetic Warehouse store in 0W-20, 5W-20, 5W-30, 10W-30 and 10W-40 viscosities.

Boosted Protection For Extended Life

Resists Oil Breakdown

AMSOIL Extended-Life 5W-30 100% Synthetic Motor OilXL Synthetic Motor Oil maintains its fluidity (viscosity) under the most extreme conditions. Some oils break down and significantly increase in viscosity after extended periods of high-temperature operation. These changes can cause excessive oil consumption, engine deposits, accelerated wear and difficult cold-starts. The GM Oxidation and Deposit (GMOD) Test consists of a 5.7L V8 engine running at 293ºF (100º hotter than normal) for 100 hours. These severe operating conditions test an oils ability to control viscosity increase, deposits and oil consumption. The testing revealed that AMSOIL XL Synthetic Motor Oil provides 64 percent more protection against oil breakdown1 than required by the GM dexos1® Gen 2 specification, ensuring protection in extreme temperatures.

Protects Pistons from Low-Speed Pre-Ignition

XL Synthetic Motor Oil features unique chemistry proven to protect your engine against the harmful effects of low-speed pre-ignition (LSPI). LSPI is the spontaneous ignition of the fuel/air mixture prior to spark-triggered ignition. Most new engines feature gasoline direct-inject (GDI), often coupled with a turbocharger. These technologies heighten the possibility of LSPI events, which can destroy pistons and connecting rods. A properly formulated motor oil is critical for protecting your engine against LSPI.

Original equipment manufacturers (OEMs) like GM have addressed the issue by designing tests to determine a motor oil’s ability to prevent LSPI. XL Synthetic Motor Oil achieved 100 percent protection against LSPI2 – zero occurrences were recorded throughout five consecutive tests.

Keeps Engines Clean

AMSOIL XL Synthetic Motor Oil is fortified with detergent and dispersant additives. Its boosted additive package effectively raises the total base number (TBN) to neutralize acids and resist sludge, corrosion and carbon deposits. XL provides 25 percent more cleaning power3 to help keep your engine running smoother, longer.

Reduces Maintenance

Motorists, business owners and fleet managers benefit from the boosted engine protection of AMSOIL XL Synthetic Motor Oil. Frequent oil changes are expensive, time-consuming and inconvenient. The extra protection built into XL can provide extended drain intervals up to 12,000 miles or one year4, if you choose, allowing you to change oil on your schedule, reduce maintenance, save money and reduce waste oil.

Maximizes Fuel Economy & Maintains Low Emissions

XL Synthetic Motor Oil is licenced by the American Petroleum Institute (API) to meet and exceed the requirements commonly found in owner’s manuals. It excels in fuel-economy testing, earning the additional “Resource Conserving” designation5 from the API. XL is also friendly toward modern emissions control systems, promoting proper operation of catalytic converters for optimum service life and low exhaust emissions.

API SN Plus: In the Fast Lane

AMSOIL is ahead of the game with three lines of motor oil that achieved 100 percent protection against LSPI.1

You can always expect AMSOIL to be in the lead. Quality and performance is where our dedication lies. No stockholders to cloud the decision making process!!
