AMSOIL 20W-40 100% Synthetic V-Twin Motorcycle Oil



AMSOIL 15W-60 and 20W-40 Synthetic V-Twin Motorcycle Oil provides Indian and Victory riders the confidence and security that comes with receiving maximum protection and performance for their bikes. It presents a premium alternative to higher-priced manufacturer-branded oils.

MVIReduces 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. Adding other oils, however, will shorten the life expectancy of AMSOIL motor oils and reduce their 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 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.

WARRANTY SECURE
AMSOIL Synthetic V-Twin Motorcycle Oil is Warranty Secure, keeping your factory warranty intact. AMSOIL Synthetic V-Twin Motorcycle Oil is a high-performance replacement for vehicle manufacturer-branded products and is also backed by the AMSOIL Limited Warranty.

    Good oil delivered
    By  TriPacer,  a  Verified Buyer  from  NE  on  June 20, 2024
    I have always liked Amsoil and thought, "why not, it's the same price as everything else". I don't know what to think about my mpg jump when I switched my bike over to Amsoil. It went from 38-39 MPG all the time to 42-43 MPG and all I changed was the oil. Hope that trend lasts....
    Bottom Line
    Yes, I would recommend this to a friend.

    A slicker oil
    By  DAVID,  a  Verified Buyer  from  Indiana  on  June 18, 2024
    I run this oil in my 2012 Road King Classic. It now has 124,000 miles on it, and the motor has never been touched. The main thing I noticed about this oil was how much quieter my top end sounds after using this oil. Twin cams are notorious for having ticky sounding top ends, and mine is no different. The sound didn't completely go away, but it got much quieter. The motorcycle also seems to be running cooler then it was. So far it's always been a great oil for me. I run AMSOIL in everything I own.
    Bottom Line
    Yes, I would recommend this to a friend.

    Great product.
    By  ARY,  a  Verified Buyer  from  Georgia   on  June 10, 2024
    This is my first time using the Amsoil on my 2021 Indian Springfield (60k miles). A noticeable improvement I noticed was that with the conventional oil when the motorcycle was cold sometimes it would not shift easily from first to second gear. It hasn’t happened so far with Amsoil. Price was fair, specially after the discount for signing up.
    Bottom Line
    Yes, I would recommend this to a friend.
