Product Highlights View Full Description

AMSOIL XL Synthetic Motor Oil is the choice for those who want to do something extra for their vehicle. Its boosted formulation delivers extra cleaning power, outstanding wear control, excellent high- and low-temperature protection and exceptional fuel economy. XL is engineered for advanced automotive technology, including turbos and direct injection. It is packed with extra engine protection, allowing you to go up to12,000-miles or one year, whichever comes first, between oil changes.

Resists Oil Breakdown
XL 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.

GM Oxidation and Deposit (GMOD) Test

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.

I started using the longer interval synthetic oil recently and did notice my gas mileage improved along with the engine running very smooth. I have to admit at first I was not sure Amsoil was able to produce a oil that could go for 10,000 miles and beyond. I took the plunge into using a longer time interval change for my car. Amsoil is a company that has dedicated probably countless hours of coming up with a synthetic that can in the real world condition do this. I have taken care of every car I've own since I want them to last me a long time. When the most recent oil change was done I was very impressed on how good the oil looked after. I recommend this oil to all my friends but some you can convince and some remain sceptable. As they say you can lead a horse to water. So I cleaned the throttle body, changed the oil and entered into my maintenance log. If you are on the fence about trying their products, trust me. Become a yearly member and you probably will not go back to whatever oil you were using. I feel Amsoil needs to keep their prices lower for members as they have done so that more people will be able to switch over without question. Cost will always be the factor on if the consumer will give the product a try. I think free shipping, reward points and sales would give existing members to purchase more in advance. Thank you to the entire Amsoil team for their commitment to protecting our engines.

I recently switched to this oil in my 4.6L f150. This truck has 106,100 miles on it. It's had motorcraft synthetic blend changed every 3k-5k miles with a fl-820 filter since new.
Immediately after switching to this oil the engine developed some cold start and low RPM knocking.
I believe this is due to the timing chain tensioners and or guides?
The tensioners rely on oil pressure to keep the chains tensioned.
So either the motorcraft was hiding a mechanical issue or this 5w20 isn't of similar viscosity to the motorcraft?
Oil sample will be sent to blackstone at 3k miles.
Still using the motorcraft fl-820 filter with this product.
I cannot recommend this product until I have more info.
