Harley-Davidson/AMSOIL Oil Chart
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 storage.
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
With AMSOIL 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
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
AMSOIL Synthetic 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
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 Motorcycle
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-
Racing or modified engines are excluded from extended drain interval recommendations.
Oil changes are at the owner’s discretion.
