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.
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
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,
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.

AMSOIL XL Synthetic Motor Oil is compatible with conventional
and other synthetic motor oils. Mixing other oils with AMSOIL
motor 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.
oil additives are not recommended for
use with AMSOIL XL Synthetic Motor Oil.
