Harley-Davidson/AMSOIL Oil Chart

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. Trust the extensive experience of AMSOIL, The First in Synthetics,® to do the best job protecting your motorcycle.

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 Wear and Deposits
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.

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.

APPLICATIONS
Engineered for use in motorcycles that require 15W-50 or 20W-50 motorcycle oil, including those made by Harley-Davidson*, Buell*, KTM*, Ducati*, Aprilia*, BMW* and Triumph*. Do not use where an API GL-4 or GL-5 gear oil is required.

*All trademarked names and images are the property of their respective owners and may be registered marks in some countries. No affiliation or endorsement claim, express or implied, is made by their use. All products advertised here are AMSOIL-engineered for use in the applications shown.

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.

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.

Comments about 20W-50 Synthetic V-Twin Motorcycle Oil:

This is my first purchase with amsoil. I am using this in my 2006 Harley Davidson Street Glide. I have put about a 1000 miles on the first oil change and the engine seems to run cooler as promised. I'll know more about performance after my next oil change. Friends swear by amsoil who gear heads like me. I'm sure I'll be pleased. The prices for preferred customers are worth the initial fee. I plan on switching my diesel truck to amsoil 25,000 oil change once I use up my current brand.

New 2016 H-D ultra limited V-Twin oils and Lubes

By 

from undisclosed

Verified Buyer

Comments about 20W-50 Synthetic V-Twin Motorcycle Oil:

bought a new 2016 Harley Davidson ultra limited and after breaking in the engine and trans I switched to Amsoil lubes through out the whole bike. Engine, trans and primary case. I have used Amsoil interceptor in my snowmobiles for years and several thousand miles and have had no engine failures so I have good reason to expect the same excellent results in my new bike.

Comments about 20W-50 Synthetic V-Twin Motorcycle Oil:

I used Amsoil 20W50 V-Twin motorcycle oil for over 80,000 miles in my 2005 Harley and it was still running strong at 120,000 when I traded up to a 2016 Harley. I specified Amsoil at the 500 mile service and have rolled up 13,000 trouble free miles already. Looking forward to another 100,000.

You Just Can't Beat Quality

By 

from undisclosed

Verified Buyer

Comments about 20W-50 Synthetic V-Twin Motorcycle Oil:

I use AMSOIL products in the Engine, Transmission and Primary case of all the Harley-Davidson motorcycles I've owned since I started riding after a 40 year hiatus in 2012.

I have also used AMSOIL in all of my air cooled Volkswagen powered vehicles for decades. You can't beat it's quality. The fact AMSOIL sells application specific lubricants that really ARE superior to "universal" lubricants is a HUGE plus too.
