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 high temperatures of air-cooled engines such as Harley Davidson® V-Twin, wet clutch lubrication, extreme pressure regions of gears and chains and rust common to short trips and storage.

AMSOIL MCV is multi-functional and fulfills the requirements of both domestic and foreign motorcycles. It 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 the best high temperature film strength (see High Temperature Viscosity Protection graph below) of all oils tested and contains a heavy treatment of anti-wear additives to reduce wear regardless of the operating conditions (see Wear Comparison graph on reverse). AMSOIL MCV 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 cleanliness.

Improved Transmission Protection

AMSOIL Synthetic Motorcycle Oils not only provide superior protection for motorcycle engines, they also provide superior gear protection, meeting API GL-1 gear lube viscosity requirements. AMSOIL Synthetic 10W-40 Motorcycle Oil (MCF) meets SAE 80W-90 gear lube requirements, while AMSOIL Synthetic 20W-50 Motorcycle Oil (MCV) meets SAE 90 gear lube viscosity requirements.

Viscosity is the most important characteristic of a lubricant. Motorcycle gears create a shearing effect that causes permanent oil viscosity loss. This thinning effect reduces the oil's ability to prevent metal-to-metal contact and wear. The stability and natural operating temperature ranges of the premium synthetic base stocks used to formulate AMSOIL Synthetic Motorcycle Oils eliminate shear and reduce wear. AMSOIL Synthetic Motorcycle Oils exhibit absolute shear stability as measured by the Kurt Orbon shear stability test.

The high temperatures and tight tolerances common to motorcycle applications also affect viscosity. The High Temperature/High Shear (HTHS) Test (ASTM D-4683) measures a lubricant's viscosity under severe high temperature and shear conditions. The more resistant an oil is to high temperature viscosity loss, the better it protects, and even a HTHS difference of 0.1 cP makes a significant difference.

AMSOIL Synthetic Motorcycle Oils exhibit higher HTHS viscosities than competing conventional and synthetic motorcycle oils. As seen in the graphs, AMSOIL Synthetic 20W-50 and 10W-40 Motorcycle Oils displayed the highest High Temperature/High Shear viscosities in their respective test groups, providing motorcycle engines and transmissions operating in the harshest conditions with superior protection against wear and viscosity loss and eliminating the need for separate gear case oils as recommended by some competitors. Synthetic 10W-40 may also be used in two-cycle transmissions.

Provides Extreme Pressure Quality 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).

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 anti-rust agents. It passes the ASTM D-1748 humidity cabinet rust test and clearly demonstrates superior rust protection (see photos below).

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 4-stroke engines. It meets SAE 90, API GL-1 gear oil requirements and is recommended for transmissions and primary chaincases. AMSOIL MCV is recommended for Harley Davidson®,
Buell®, Victory®, Ducati®, Aprilia®, BMW®, Triumph® and other motorcycles where 15W-50 or 20W-50 engine oils or SAE 90, GL-1 gear oils are used. Not recommended for shaft drive hypoid gears or where an API GL-4 or GL-5 gear oil is required.

MIXING AMSOIL
AMSOIL Synthetic 20W-50 Motorcycle Oil is compatible with conventional and synthetic motor oils; however, mixing oils may shorten the oil life expectancy and reduce the performance benefits. AMSOIL does not support extended drain intervals where oils have been mixed.

Aftermarket oil additives are not recommended for use with AMSOIL motorcycle oil.

SERVICE LIFE
Recommended for use up to twice the motorcycle manufacturer change interval (miles/hours) or one year, whichever comes first, in engines, transmissions and primary chaincases. 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 AMSOIL Ea, change the filter at standard intervals. For “off-road” use, change AMSOIL MCV at motorcycle manufacturer intervals.
Racing or modified engines are excluded from extended drain interval recommendations. Oil changes are at the
owner’s discretion.

On August 2nd our customer Matt Goforth in Springfield, VA using the AMSOIL MCV in all three sumps called back to tell us of his impressons of the oil in his Harley Electroglide. After riding multiple routes he is getting 190 miles per tank and measured 44.9 MPGs. Matt also used the AMSOIL PI Performance Improver in the tank. One bottle treats 160 gallons and restores injector performance. It's worth generally 1 MPG in larger vehicles and even more in motorcycles.
