PRODUCT
DESCRIPTION
AMSOIL High Performance
Synthetic 10W-40 Motor Oil provides superior protection and
performance in the most severe automotive driving conditions.
AMSOIL High Performance Synthetic 10W-40 Motor Oil provides a wide
range of protection in all four-cycle gasoline and diesel engines,
including pickups, RVs, cars and off-highway vehicles. It is
recommended for use in vehicles subject to stop-and-go driving,
short trips, high temperatures, frequent trailer pulling and
off-road use.
RESISTS
HIGH TEMPERATURE VAPORIZATION
Conventional motor oils tend to "boil off" in high temperatures,
losing up to 25 percent of their original weight. These vaporized
oils circulate poorly, reduce fuel efficiency and contribute to
excessive emissions and engine wear. AMSOIL High Performance
Synthetic 10W-40 Motor Oil resists vaporization. In fact, according
to the NOACK Volatility Test, which measures the weight loss of an
oil due to evaporation, AMSOIL High Performance 10W-40 only loses
7.0 percent of its weight in high temperature service, surpassing
rigorous European standards set at 13 percent weight loss in high
temperature testing. The superior vaporization resistance of AMSOIL
High Performance 10W-40 keeps engine wear, oil consumption and
emissions to a minimum, while keeping oil circulation efficient and
fuel economy high.
RESISTS
OXIDATION AND THERMAL BREAKDOWN
Conventional oils oxidize in high operating temperatures, producing
sludge and deposit build-up that contribute to corrosion, increased
engine wear and decreased fuel economy. AMSOIL High Performance
Synthetic 10W-40 Motor Oil resists oil breakdown, maintaining its
cooling and lubricating properties and providing extended drain
intervals. It continues to provide maximum protection at
temperatures that oxidize conventional oils. The advanced heat
transfer capabilities and high lubricity of AMSOIL High Performance
Synthetic 10W-40 Motor Oil keep engines running in their optimum
temperature range for top performance and long life.
PROVIDES
HIGH SHEAR STABILITY
AMSOIL High Performance Synthetic 10W-40 Motor Oil surpasses the
North American SAE and European ACEA oil specifications for high
temperature/high shear (HTHS) viscosity. It retains its viscosity
at temperatures and loads that cause conventional oils to shear
back to a lower viscosity. AMSOIL High Performance Synthetic 10W-40
Motor Oil maintains an extremely protective viscosity of 3.93 cP at
302°F (150°C) in the ASTM D 4683 High Temperature/High Shear Test,
significantly exceeding test limits.
PROVIDES
LOW TEMPERATURE PROTECTION
AMSOIL High Performance Synthetic 10W-40 Motor Oil remains fluid at
temperatures as low as -54°F (-48°C), permitting easy engine
cranking for quick starts. During sub-zero temperatures, it flows
to all parts of the engine much quicker than conventional petroleum
oils, greatly reducing the rate of wear and increasing engine
life.
RESISTS
DEPOSIT FORMATION
AMSOIL High Performance Synthetic 10W-40 Motor Oil is highly
resistant to oxidation, running significantly cleaner than
conventional motor oils. AMSOIL 10W-40 has a superior
detergent/dispersant additive package that, when tested after tens
of thousands of miles of use in the crankcase, still exhibits
outstanding deposit control.
INHIBITS
RUST AND CORROSION
AMSOIL High Performance Synthetic 10W-40 Motor Oil contains special
rust and corrosion inhibitors to protect iron parts, as well as
copper, lead and aluminum bearing materials.
PROVIDES
EXTENDED DRAIN INTERVALS
AMSOIL High Performance Synthetic 10W-40 Motor Oil features a
superior synthetic composition and advanced performance additives,
performing much longer than competing conventional and synthetic
oils. No other major oil manufacturer matches AMSOIL's 25,000-mile
or one-year drain interval recommendations.

MIXING AMSOIL
- AMSOIL High Performance Synthetic 10W-40 Motor Oil is compatible with conventional petroleum oils;
- however, mixing AMSOIL 10W-40 with a conventional oil will shorten the drain period of AMSOIL 10W-40.
- Engine
oil additives or after-market products are not recommended for use
with AMSOIL 10W-40.
- In
personal cars and light-duty trucks with non-turbocharged gasoline
engines, drain oil at 25,000 miles or one-year intervals, whichever
comes first.
- In
turbocharged gasoline engines, change oil at three times the engine
manufacturer's recommended drain interval or six months, whichever
comes first.
- In high
performance and racing engines, change oil at intervals specified
by used oil analysis.
- In
light-duty and non-turbocharged diesel engines, change oil at two
or more times the engine manufacturer's recommended drain intervals
if the findings of used oil analysis support those drain intervals
or six months, whichever comes first.
- In heavy
duty and turbocharged diesel engines, change oil at two or more
times the engine manufacturer's recommended drain intervals if the
findings of used oil analysis support those drain intervals or six
months, whichever comes first.
- In
motorcycle engines, change oil according to manufacturer's
recommendations, without oil filtration. With oil filtration
(AMSOIL SDF & SMF Filters), up to 2 times longer than
manufacturer's recommendations or 6 months, whichever comes
first.
- In marine craft and occasionally used gasoline engines, change oil at three times the engine manufacturer's recommended drain interval or one year, whichever comes first.
- In fleet
vehicles and industrial gasoline engines, change oil at three times
the engine manufacturer's recommended drain interval or six months,
whichever comes first.
