AMSOIL SAE 20W-50 Synthetic Motorcycle Oil AMSOIL Synthetic Motorcycle Oils have been reformulated with new high performance additive technology that provides even greater multi-functional benefits for the special requirements of motorcycle applications. These independent and exclusive new AMSOIL formulations provide second-to-none viscosity protection for hot-running American and foreign motorcycle engines, transmissions and primary chaincases. Product Code: MCV See product application notes for Harley Davidson Motorcycles

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.

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.

The AMSOIL Advantage
Motorcycle manufacturers want the best protection possible for their equipment, calling for rugged oils that exhibit high-temperature deposit control additives. AMSOIL Synthetic Motorcycle Oils are specially formulated with the best synthetic basestocks and high-performance additives to provide tough lubricating protection for all four-cycle motorcycle and ATV engines in the most demanding operations.

AMSOIL Motorcycle Oils are formulated for both water-cooled engines and the unique demands presented by air-cooled V-twin motorcyle engines, including Harley-Davidson. Conventional petroleum oils break down and oxidize when faced with high temperatures, such as those experienced when idling in traffic, contributing to the formation of deposits, sludge and varnish. AMSOIL withstands oil breakdown and oxidation in high temperatures, holds contaminants in suspension and keeps engines running cool and clean.

Zinc and phosphorus additives are extremely important to engines faced with high-pressure conditions, especially motorcycle engines, which typically have steep cam slopes, creating high pressure between the parts. In motorcycles, friction modifiers (prevalent in automotive oils) have been attributed to engine start failures, a rough running feel, increased fuel consumption due to higher engine stall speeds and other problems. AMSOIL Synthetic 10W-40 and 20W-50 Motorcycle Oils have beefier antiwear and detergent/dispersant packages with no friction modifiers, keeping motorcycles running smoothly and efficiently, while allowing for extended drain intervals of up to twice the manufacturers' recommendations.

AMSOIL Synthetic Motorcycle Oils contain significantly higher levels of zinc and phosphorus than competing oils, and while simply adding more zinc and phosphorus doesn't insure good performance, AMSOIL has formulated motorcycle oils with the best additives in the optimal quantities to provide superior wear protection.

A Four-Ball Wear Test was conducted at 302°F/150°C, a higher temperature that would typically be associated with motorcycle oil operating temperatures in extreme high-performance situations. AMSOIL motorcycle oils protect better in higher temperatures than any of the tested motorcycle oils do, leaving a wear scar up to 80 percent smaller.

Harley Gets New Life With AMSOIL

Roy Goyette, Naples, Florida, took advantage of the advanced technology of AMSOIL synthetic motor oils and lubricants to breathe new life into a beat-up old Harley. Goyette got started on the project in May 2006 when a good friend asked him to restore the old Harley. "I was told that it was an old 165 Harley that had been stored for many years." Goyette said.

"I use AMSOIL products all the way through the bike," Goyette said. "I used the Synthetic Water Resistant Grease, HP Injector 2-Cycle Oil in a premium-mix form, SAE 10W-40 Synthetic Motorcycle Oil in the transmission, Heavy Duty Metal Protector for the chain, Metal Protector in lots of areas and Mothers Products on the final build. Thanks for a great line of products." (read article)

"AMSOIL INC. warrants that the use of its lubricants will not cause mechanical damage to any mechanically sound equipment when AMSOIL INC. products are used in full compliance with the company's recommendations and instructions."

FULL WARRANTY

AMSOIL synthetic motor oils are formulated to surpass engine test specifications, offering protection far greater than competing motor oils for extended drain intervals. Most synthetic oil manufacturers make no claim to extended drain intervals, deferring to the maintenance schedule provided by the vehicle manufacturer. With its unparalleled oil and warranty program, AMSOIL offers consumers unprecedented protection and economics.

Another AMSOIL First

More than 20 years ago, AMSOIL began using the NOACK volatility test as a comparison tool and measurement of quality. Back then, nearly every oil tested side-by-side with AMSOIL synthetic motor oils failed, and those that passed barely squeaked by. Other oil companies paid no attention to NOACK results until Ford Motor Company made it a requirement for service fill oils, validating what AMSOIL had said all along.
