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.

    Best oil ever
    By  EDWARD,  a  Verified Buyer  from  Venus, TX  on  June 11, 2025
    I’ve been using AMSoil since a little after it’s inception into the market and I will not go back to any other oils, providing AMSoil stays in business. I use it in all my vehicles, car truck & motorcycle. When I had a gas powered mower, I even used the used oil in my lawn equipment. Needless to say I’m a huge fan and when I did start using it, they had a replacement warranty on any oil related failure. I don’t know if they still have that warranty, but I’ll keep using their oil anyway. Also, when you’re a preferred customer the price is very competitive.
    Bottom Line
    Yes, I would recommend this to a friend.

    Engine, Transmission, Primary Oil All-In-One
    By  BootCampBob,  a  Verified Buyer  from  Upstate New York  on  June 10, 2025
    I've been running a 2022 Indian Challenger 108 Cu In V-Twin on this oil since new / break-in. The bike now has 15,467 miles on it. Indian Motorcycles use engine oil for the clutch / transmission and primary lubrication, as well as the engine, unlike another American V-Twin maker that uses separate fluids for each, so the demand on this oil is critical for Indians. I wouldn't use this oil if it didn't out-perform everything else on the market. Not only does the engine run quieter than when using other oils (including the manufacturer's branded product, and these engines are known for being noisy), the transmission shifts easier as well. I've used AMSOIL Signature Blend in my high performance cars and truck since 2008 with similar results. Using AMSOIL V-Twin Formula 15W60 was an easy decision for my Indian. It hasn't disappointed a bit.
    Bottom Line
    Yes, I would recommend this to a friend.

    2020 street glide oil chg...
    By  PETE,  a  Verified Buyer  from  NH  on  June 09, 2025
    I was disappointed this time. The "kit" came with oil, and filter, but no o-ring for the drain plug as clearly pictured and called out in the description. No biggie, just a trip to the NAPA parts store and got the job done. QC at the assembly plant for the kit must've had the day off???? It would be good if there was a "Deluxe" oil change kit that included primary fluid and an extra qt of 20-50 to do the trans.
    Bottom Line
    Yes, I would recommend this to a friend.
