XL 100% Synthetic Motor Oil – Best Value in Omaha

Our middle tiered synthetic outperforms all our competitions top-tiered synthetic. Better performance, longer life, better price and it’s “Really 100% Synthetic” Something the others can’t say. 

The new XL Synthetic Motor Oil formulation delivers more cleaning power, complete protection against oil breakdown and new extended-drain recommendations.

XL Synthetic Motor Oil (XLZ 0w-20, XLM 5W-20, XLF 5w-30, XLT 10w-30, and XLO 10w-40)

Technology only available from AMSOIL

XL Synthetic Motor Oil features a boosted formulation that delivers more cleaning power and promotes longer engine life. It’s engineered for advanced automotive technology, including turbochargers and direct injection. XL is the perfect choice for enthusiasts who want to do something extra for their vehicles for a great price. The XL out performs all other top tiered oils found in most retail establishments.

  • 25 percent more cleaning power1
  • Achieved 100 percent protection against LSPI2
  • Extra protection that lasts up to 12,000 miles or 1 year, whichever comes first
  • API-licensed to meet the requirements commonly found in owner’s manuals

Fights Breakdown

XL Synthetic Motor Oil maintains its fluidity (viscosity) under the most extreme conditions. Some oils break down after extended periods of high- or low-temperature operation. These viscosity changes can lead to numerous issues:

  • Excessive oil consumption
  • Engine deposits
  • Accelerated wear
  • Difficult cold starts

The GM Oxidation and Deposit (GMOD) engine test simulates severe operating conditions to assess a motor oil’s 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 breakdown, ensuring protection in extreme temperatures.3

XL = Extended Life

AMSOIL XL Synthetic Motor Oil now provides even longer-lasting engine protection. Drain intervals can now be extended up to 12,000 miles, one year or longer when recommended in owner’s manuals or indicated by electronic oil life monitoring systems. This recommendation extends to aftermarket, original equipment manufacturer (OEM) or AMSOIL Ea® Oil Filters as well – simply replace the filter at every oil change.

Protects Pistons from Low-Speed Pre-Ignition

Like Signature Series and OE, XL features an advanced detergent system to protect vital engine parts like pistons and connecting rods. Most new engines feature gasoline direct-injection (GDI), often combined with a turbocharger to boost power and improve fuel economy. These new technologies pose significant challenges to motor oil, one of which is low-speed pre-ignition (LSPI). LSPI is the spontaneous ignition of the fuel/air mixture prior to spark-triggered ignition. It occurs in today’s advanced engines and is much more destructive than typical pre-ignition.

OEMs like GM* have addressed the issue by designing tests to determine a motor oil’s ability to prevent LSPI. The GM test allows up to five LSPI events to receive a passing score. XL Synthetic Motor Oil provided 100 percent protection against LSPI2 – zero occurrences were recorded.

No other on the shelf brand can pass this test 100% as all three tiers of AMSOIL can. This will in the future make the difference of cars making it through the next intersection after an oil change. Car manufacturers say the motor oil is the issue with future high efficiency engines.. Well AMSOIL has already advanced past this stage!!

Article on the Definition of Synthetic Having New Meaning from our Dealer Magazine 2014 regarding how Motor Oil’s labeled as “Full Synthetic” get away with it although there isn’t one ounce of synthetic in the bottle. Stockholder based companies are there for profits first so they relish rather than try to correct the definition change.

XL 5W-30 Synthetic Motor Oil

To match this 100% synthetic technology which is being added to all AMSOIL lines without a price increase would mean a $2 per quart increase by the competition if they wanted to keep stock holders value, thus they will continue using Group III petroleum base stocks which they legally refer to as “Full Synthetic” although scientifically that is not so. Until regulation is put into place you can always trust AMSOIL for true synthetic lubricants which cannot be matched in their performance!
