Product Highlights View Full Description

AMSOIL 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, wet-clutch lubrication, extreme-pressure regions of gears and chains, and rust protection.

AMSOIL 20W-40 Synthetic V-Twin Motorcycle Oil provides Indian and Victory riders with the confidence and security that comes with receiving maximum protection and performance for their bikes. It presents a premium alternative to higher-priced manufacturerbranded oils.

Reduces Friction, Heat and Wear
AMSOIL Synthetic V-Twin Motorcycle Oil is engineered to protect critical components in high-heat conditions. It exceeds the standard for high-temperature film strength to deliver excellent wear protection (see graph) and contains a heavy treatment of anti-wear additives to reduce wear regardless of operating conditions. AMSOIL Synthetic V-Twin Motorcycle Oil is thermally (heat) stable and contains maximum levels of oxidation-inhibitor additives. It is extremely resistant to breakdown and is engineered to prevent damaging sludge and carbon deposits for superior engine cleanliness.

Provides Anti-Wear Protection for Gears and Chains
AMSOIL Synthetic V-Twin Motorcycle Oil is shear stable and resists thinning from mechanical activity. It performs like a gear lube without the negative effects of extreme-pressure additives, such as poor wet-clutch performance.

Delivers Superior Rust Protection
Motorcycles are prone to rust from storage, humidity and short drives. Rust can cause major damage, such as uncontrolled 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, providing outstanding protection against rust and corrosion.

Catalytic-Converter Compatible
AMSOIL Synthetic V-Twin Motorcycle Oil meets the requirements for emission-system protection and is designed for use in motorcycles with catalytic converters.

Provides Excellent Wet-Clutch Performance
AMSOIL Synthetic V-Twin Motorcycle Oil delivers the confidence of quiet, smooth shifting and positive clutch engagement. It controls heat and helps prevent slippage and glazing.

APPLICATIONS
Use AMSOIL 20W-40 Synthetic V-Twin Motorcycle Oil in motorcycles that require 20W-40 motorcycle oil and any of the specifications listed below, including those made by Victory* and Indian*.

  • JASO MA
  • API SM
  • ILSAC GF-4

COMPATIBILITY
AMSOIL Synthetic V-Twin Motorcycle Oil is compatible with other conventional and synthetic motor oils. Mixing AMSOIL motor oils with other oils, however, will shorten the oil’s life expectancy and reduce the performance benefits. Aftermarket oil additives are not recommended for use with AMSOIL Synthetic V-Twin Motorcycle Oil.

SERVICE LIFE
For on-road use in engines and transmissions: When paired with an AMSOIL Ea® Motorcycle Oil Filter, AMSOIL 20W-40 Synthetic V-Twin Motorcycle Oil is capable of providing premium protection for up to 2X the motorcycle manufacturer-recommended change interval or one year, whichever comes first. Change other brand oil filters at standard intervals.

For off-road use in engines and transmissions: Change AMSOIL 20W-40 Synthetic V-Twin Motorcycle Oil at the standard motorcycle manufacturer-recommended change interval.

For racing or in engines modified from the original factory design: no change interval recommendation is made; oil changes are at the owner's discretion.

Will only use Amsoil in my motorcycle.

By 

from Thomson, Illinois

Verified Buyer

Comments about 20W-40 Synthetic V-Twin Motorcycle Oil:

I have used Amsoil in my motorcycles since 2012, and have experienced smoother, quieter idling engine, smoother shifting and better gas mileage. I currently own a 2017 Indian Roadmaster, and have not been disappointed with Amsoil products as I'm getting the same results in the Indian, plus it seems to run cooler. Thank you for great products.

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!

By 

from Silverdale, Wa.

Verified Buyer

Comments about 20W-50 Synthetic V-Twin Motorcycle 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?

  • How would you describe yourself?:
  • I love my vehicles / toys
  • What kind of vehicle/equipment do you have?:
  • 2001 HD Road King
