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.

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. After 250 hours (13,647 miles) on an engine dyno, AMSOIL Synthetic V-Twin Motorcycle Oil eliminated piston scuffing and wear for long engine life and maximum power (see image).

Helps Prevent Wear

Withstands Extreme Heat
Big, powerful V-twin engines run extremely hot, especially in summer during stop-and-go rally or parade traffic. High heat breaks down oil formulated for standard service, inviting wear and performance-robbing deposits. AMSOIL Synthetic V-Twin Motorcycle Oil is formulated with naturally heat-resistant synthetic base oils that resist oxidation in extreme heat. Its unique additive system helps keep engines clean and running efficiently in the toughest riding conditions.

Extreme-Pressure 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 Motorcycle Oil contains special antirust agents. It passes the ASTM D1748 humidity cabinet rust test, demonstrating superior rust protection to help your engine achieve maximum performance and long life.

  • Resists extreme heat
  • Retains viscosity for excellent wear protection
  • Convenience of one lubricant for all three sumps

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
Use in motorcycles that require 15W-50 or 20W-50 motorcycle oil and any of the specifications listed below, including those made by Harley-Davidson*, Buell*, Ducati*, Aprilia*, BMW* and Triumph*.

JASO MA/MA-2 • API SG/SL/CF/CG-4 • ISO-L-EMA2

Do not use where an API GL-4 or GL-5 gear oil is required.

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.

This is the only oil for your engines...

I use this oil in my Harley Davidson. First time I used it in my 2013 Street Glide FLHX 103ci motor just got it back from putting a stage 4 Racing Kit in it and put almost 46.000 miles on it in 3 years and used the 60 weight full synthetic in the motor transmission and primary and changed it every 5000 miles witch didn't take long. It tuned on the dyno at 112 HP and 121 pounds of torque. After spending all that money on the engine I won't it a oil to keep it new inside with no ware on the parts and that's what I got from AMSOIL. Now I own a 2017 Street Glide 107ci and had some work done on that motor also and it is a BAD. It pulls the wheal 1st 2nd and 3rd gear and don't Know when to stop running. After the break in oil was ready to be changed I also had the motor work done on it also and had them to put the best in it. So Y not use the best oil so I had them put 20w 50 in all of Motor Transmission and Primary. Now I just turned it over to 4000 miles on the engine now after are last trip and I don't baby it I run it on the Interstate 80 85 90 depends on how the traffic is flowing and I will fall in and roll with it with no worries about my engine because I know its being protected and staying cooler and no ware and tare. Also the shifting is quitter and smoother and the Transmission like the Engine smooth and no ware and tare. Now I'm fixing to order me some AMSOIL because it is getting close to my oil change and don't forget about there Oil Filter It does the Job that no other filter can and that is all the bad stuff don't get through keep that oil Pure.

I put this stuff in a 2010 Ultra Limited that I bought with 32K on it. 200 miles later heretofore unheard
noises started, am in the process of repairs. So far the front exhaust lifter is trash and it took out the
cam with it, don't know the full extent of damage yet. So you tell me "Which came first, the chicken or
the egg?
