AMSOIL Synthetic SAE 60
Motorcycle Oil (MCS) is a premium oil designed for those who demand the absolute best lubrication
for their motorcycles. AMSOIL Motorcycle Oil is the result of extensive research, and it is
specially formulated to excel in all areas unique to motorcycles, including high engine RPM,
wet-clutch lubrication, extreme-pressure regions of gears and rust common to short drives and
AMSOIL SAE 60 Motorcycle Oil features superior heat resistance and wear protection.
It is shear-stable and helps maintain proper oil pressure in elevated temperatures. AMSOIL
Synthetic SAE 60 Motorcycle Oil stops viscosity breakdown (loss), protects gears and chains, and
meets SAE 140, API GL-1 gear oil requirements. It is multi-functional and fulfills the requirements
of both domestic and foreign motorcycles. AMSOIL SAE 60 Motorcycle Oil outperforms other
conventional and synthetic motorcycle oils.
AMSOIL, the leader in synthetic lubrication, produced the world’s first
API-qualified synthetic motor oil in 1972. Trust the extensive experience of AMSOIL, The First in
Synthetics,® to do the best job protecting your motorcycle.
Reduces Friction, Heat and Wear
In high heat
conditions, engine protection is not sacrificed with AMSOIL Synthetic Motorcycle Oil. It has
exceptional high-temperature film strength and contains a heavy treatment of anti-wear additives to
reduce wear regardless of operating conditions. AMSOIL SAE 60 Motorcycle Oil is thermally (heat)
stable and contains maximum levels of oxidation inhibitor additives. It is extremely resistant to
breakdown and engineered to prevent damaging sludge and carbon deposits for superior engine
Extreme-Pressure Protection for Gears
Synthetic Motorcycle Oil, there is no need for a separate transmission lubricant. It is
shear-stable and will not thin out from mechanical activity. AMSOIL SAE 60 Motorcycle Oil performs
like a gear lube without the negative effects of extreme-pressure additives.
Superior Rust Protection
Motorcycles are prone to
rust from storage, humidity and short drives. Rust can cause major damage such as roller bearing
failure, uncontrolled wear, compression loss and blow-by. Good rust protection, however, comes by
design and is not natural to engine oils. Unlike many motorcycle oils, AMSOIL Synthetic Motorcycle
Oil contains special anti-rust agents.
Excellent Wet-Clutch Performance
SAE 60 Motorcycle Oil contains no friction modifiers and promotes smooth shifting and positive
clutch engagement. It controls heat and helps prevent slippage and glazing, while its high TBN
helps improve clutch life by resisting the acids that can degrade clutch material.
AMSOIL Synthetic SAE 60 Motorcycle Oil
is recommended for early-model air-cooled V-Twin engines where a 60-weight motor oil is specified.
SAE 60 motor oils are commonly used in Harley-Davidson® Knucklehead, Panhead, Shovelhead and
big-bore motorcycles. AMSOIL Synthetic SAE 60 Motorcycle Oil meets API SG, SL/CF; API GL-1; JASO
MA/MA2 and ISO-L-EMA2.
AMSOIL Synthetic SAE 60 Motorcycle
Oil is compatible with conventional and synthetic motor oils. Mixing AMSOIL motor oils with other
oils, however, will shorten the oil’s life expectancy and reduce its performance benefits. AMSOIL
does not support extended drain intervals where oils have been mixed.
Aftermarket oil additives are not recommended for use with AMSOIL Synthetic
Recommended for use up to twice the
motorcycle’s manufacturer-recommended change interval (miles/hours) or one year, whichever comes
first, in engines and transmissions. For Big Twin Harley-Davidson transmissions only, follow the
Harley-Davidson recommended drain interval for synthetic oil of up to 20,000 miles or one year,
whichever comes first. When using an engine filter other than an AMSOIL Ea Motorcycle Oil Filter,
change the filter at standard intervals.
For off-road use, change AMSOIL Synthetic Motorcycle Oil at the motorcycle’s
manufacturer- recommended intervals.
Racing or modified engines are excluded from extended drain interval
recommendations. Oil changes are at the owner’s discretion.
