PRODUCT DESCRIPTION
AMSOIL Synthetic 20W-50 Motorcycle Oil (MCV) is a premium oil designed for those who demand the absolute best lubrication for their motorcycles. AMSOIL MCV is the result of extensive research, and it is specially formulated to excel in all areas unique to motorcycles, including the high temperatures of air-cooled Harley Davidson V-Twin engines, transmissions, and primary chain cases.
Reduces Friction, Heat, and Wear
In high heat conditions, engine protection is not sacrificed with AMSOIL Synthetic Motorcycle Oil. It has the best high temperature film strength (see High Temperature Viscosity Protection graph below) of all oils tested and contains a heavy treatment of antiwear additives to reduce friction and wear regardless of the operating conditions.
Friction consumes power and creates heat. When it is reduced, more horsepower is produced and the engine runs cooler.
If you want maximum performance and the confidence that you have the toughest motorcycle oil in your expensive Harley, then AMSOIL Motorcycle Oil is for you. Order some today.
AMSOIL MCV is thermally (heat) stable and lasts much longer that other motorcycle oils. For most on road use you can safely double you factory oil change intervals. It is extremely resistant to breakdown and engineered to prevent damaging sludge and carbon deposits for superior engine cleanliness.
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.

SERVICE LIFE
For "on road" use in engines, transmissions and primary chaincases, change AMSOIL MCV and AMSOIL engine oil filter at twice the motorcycle manufacturer change interval or one year, whichever comes first. Change other brand oil filters at standard intervals.
For "off road" use in engines, transmissions and primary chaincases, change AMSOIL MCV at the standard motorcycle manufacturer change interval.
For racing or in engines modified from the original factory design, no change interval recommendation is made. Oil changes are at the owner's discretion.
Provides Extreme Pressure Protection for Gears
With AMSOIL MCV, there is no need for separate transmission or primary chaincase lubricants. It is absolutely shear stable and will not thin out from mechanical activity. AMSOIL MCV performs like a gear lube without the negative effects of extreme pressure additives. In the FZG gear test, AMSOIL MCV achieved a perfect score with a "zero" wear rating (see photos below).

The Best Motorcycle Oil Filter
 A full-flow filter specifically designed for extended drain intervals and severe service for motorcycle applications.
Provides superior filtering efficiency, engine protection, and greater capacity than other popular filters.
These filters have the extra capacity to last as long as AMSOIL Synthetic Motorcycle Oil. Change other brand oil filters at standard intervals.

Delivers 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 MCV contains special antirust agents. It passes the ASTM D-1748 humidity cabinet rust test and clearly demonstrates superior rust protection.
Provides Excellent Wet Clutch Performance
AMSOIL MCV contains no friction modifiers and promotes smooth shifting and positive clutch engagement. AMSOIL MCV controls heat and prevents slippage and glazing, and its high TBN resists acids that can degrade clutch material, helping improve clutch life.
APPLICATIONS
AMSOIL Synthetic 20W-50 Motorcycle Oil is recommended for air or liquid cooled engines.
Meets SAE 90, API GL-1 gear oil requirements and is recommended for transmissions and primary chaincases.
AMSOIL MCV is recommended for Harley Davidson motorcycles whenever 15W50 or 20W50 engine oils or SAE 90, GL1 gear oils are used.
Not recommended for shaft drive hypoid gears or where an API GL4 or GL5 gear oil is required.
