Product Description

AMSOIL 20W-50 Synthetic V-Twin Motorcycle Oil is a premium oil designed for those who demand the absolute best lubrication for their motorcycles. It is the result of extensive research and is specially formulated to excel in all areas unique to motorcycles, including the high temperatures of air-cooled engines such as Harley-Davidson* V-twins, wet-clutch lubrication, extreme-pressure regions of gears and chains and rust common to short trips and storage.

AMSOIL Synthetic V-Twin Motorcycle Oil is multi-functional and fulfills the requirements of both domestic and foreign motorcycles. AMSOIL, the leader in synthetic lubrication, produced the world's first API-qualified synthetic motor oil in 1972.

Erik Buell Talks About AMSOIL Motorcycle Oils

Withstands Extreme Heat

To prove its extreme-heat performance, AMSOIL 20W-50 Synthetic V-Twin Motorcycle Oil was installed in a 2012 Harley-Davidson FXDB Dyna Street Bob* motorcycle. After deactivating the electronic temperature controls to increase severity, the engine was subjected to extensive idle time broken by short bursts of revving to simulate the intense heat conditions of a rally or parade route. Despite little air flow and cylinder temperatures reaching more than 500°F, the oil maintained viscosity and delivered outstanding protection (see graph).

Reduces Friction, Heat and Wear
AMSOIL Synthetic V-Twin Motorcycle Oil contains a heavy treatment of anti-wear additives to reduce wear regardless of the operating conditions. It is thermally (heat) stable and contains maximum levels of oxidation inhibitor additives. AMSOIL Synthetic V-Twin Motorcycle Oil is extremely resistant to breakdown and engineered to prevent damaging sludge and carbon deposits for superior engine cleanliness.

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.

Extreme heat test results

Provides Extreme Pressure Quality Protection for Gears and Chains

AMSOIL Synthetic V-Twin Motorcycle Oil delivers exceptional protection in transmissions and primary chaincases. It is absolutely shear stable and will not thin out from mechanical activity. AMSOIL 20W-50 V-Twin Motorcycle Oil performs like a gear lube without the negative effects of extreme-pressure additives. In the FZG gear test, AMSOIL achieved a perfect score with a "zero" wear rating.

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, wear, compression loss and blow-by. Good rust protection, however, comes by design and is not natural to motor oils. Unlike many motorcycle oils, AMSOIL Synthetic V-Twin Motorcycle Oil contains special anti-rust agents. It passes the ASTM D1748 humidity cabinet rust test, demonstrating superior rust protection to help your engine achieve maximum performance and long life.

Provides Excellent Wet Clutch Performance

AMSOIL 20W-50 Synthetic V-Twin 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.

Lowers Friction, Heat as well as Wear

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.

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 20W-50 Synthetic V-Twin Motorcycle Oil at motorcycle manufacturer-recommended intervals.

Racing or modified engines are excluded from extended drain interval recommendations. Oil changes are at the owner's discretion.

COMPATIBILITY

AMSOIL 20W-50 Synthetic V-Twin Motorcycle Oil is compatible with other synthetic and conventional motor oils. Mixing AMSOIL 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 Oils.

This is the only motor oil I will use in my Harley.

What I noticed immediately was how much cooler the motor runs. I have used this product since my bike was new and won't consider using anything else.

Amsoil is the best.

I purchased the 20w50 for my 1999 Harley Davidson Dyna Wide Glide. I will only use Amsoil in my motorcycle. It is the best oil I've ever used and I have used many other brands. I am confident in its ability to never break down or fail for any reason.

Coolest oil!

This oil has the best resistance for heat and distance. Runs my motor at least 10 degrees cooler than any other. Motor runs quiet, shifts smooth, oil does not break down under pressure.
If you have any questions about its performance hears my answer:
I have a 2001 Road King with over 200,000 miles.
I rebuilt the top end at 124,000 miles.
So the bottom end and the gear box are all original (200,000).
I ride it everyday. I don't baby it.
Oil change every 4,000 miles (Tranny every 8,000).
ANY OTHER QUESTIONS?

Great product for Harley's

I've been using this product for my Harley over the years, and I find it works better than some of the other oils I tried. Although it would be nice if Amsoil would bring down their prices.
