AMSOIL Synthetic 20W-50 Motorcycle Oil is recommended for air or liquid cooled 4-stroke engines. 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.

Product Application Specs
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.
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 Friction, Heat and Wear
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.
In high heat conditions, engine protection is not sacrificed with AMSOIL Synthetic Motorcycle Oil. It has exceptional high-temperature film strength and contains a heavy treatment of anti-wear additives to reduce wear regardless of operating conditions.
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.
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.
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.
AMSOIL Synthetic 20W-50 Motorcycle Oil is compatible with conventional and synthetic motor oils; however, mixing oils may shorten the oil life expectancy and reduce the performance benefits. AMSOIL does not support extended drain intervals where oils have been mixed.
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.
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.
This product is not expected to cause health concerns when used for the intended application and according to the recommendations in the Material Safety Data Sheet (MSDS).

Also, some are scared to run "Full Synthetic" in their bikes, fearing clutch slippage. It's in both my wife's Chief and my Springfield. No slippage! There are no friction modifiers in this, so it's good to go for wet clutches. I will continue to use it.

I have used Amsoil in my last two bikes. I always found the oil to meet or exceed my expectations consistently. I travel lots, putting on 20 to 25,000 Kms per year which is a few considering our short season. I usually run one trip to the Southern US so the temps can be hot. I never had an issue until last year. In 2017, I traveled through Nevada, parts of California and Northern Arizona in the first two weeks of June. Temps reached 45C, or about 115 F. I had installed a new motor in 2015. I was advised to use a different synthetic oil, which worked fine in cooler temps. On this trip the other oil broke down completely. My oil pressure fell and the motor became noisy. I changed to Amsoil 20-50 and had no more issues. From here on, it will be Amsoil for me. It stands up much better to extreme conditions.

It is getting too hard to find parts for her so we made the decision to find her a new home. The motor was still rock solid along with the tranny and primary but we were concerned mainly with stator and fuel injection. It had the old Magnetti Marelli injection system that was only used 99 thru 01. Amsoil 20w50 V-Twin oil kept the motor, tranny and primary chugging right along!!!!

Been buying Amsoil products for almost 10 years now. I've used it for three different bikes and have always gotten outstanding life out of their oil. Kawasaki, Yamaha, Harley Davidson. Any time I've taken them to professional mechanics for major work I can't complete on my own, they always compliment the condition of the engine because it's still running smooth.

I have used this in any of my Harleys over the last 8 years. The bike seems to run quieter and generates less heat. Don't use it during the break-in period, or the rings will never seat properly. Use Harley's oil (360) for the first 5000 miles, then switch over.

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 started using AMZOI: products a few years ago, signed up as a preferred customer and I am a true believer in their products My wife and I each ride Harley's and feel the AMZOIL full synesthetic lubricants are the best on the market. There are two things that will cause an engine to fail, heat and friction. Using AMZOIL is one of the best ways to prevent friction and protection for heat.

I have been an Amsoil Preferred Customer for many years ,I use Amsoil for all of my vehicles and equipment. I have never had a single oil related failure, or any failure for that matter. I just did my first oil change on my 2017 Street Glide and noticed a difference right away in the running and smoothness of the engine. My only wish is that Amsoil will put together a "Kit" for the 2017 Harley Davidson Milwaukee 8 owners. We use 4.5 quarts of crankcase oil instead of 4 quarts. Help us oil Amsoil !

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).

With HD synthetic oil, engine gets really hot in stop and go traffic. As the heat increases engine gets louder also. I am now running Amsoil 20w50 motorcycle oil because friends recommended it.
This oil changed the way engine behaves (cold or hot). The bike idled so much more quieter immediately after installing Amsoil! There's no more overheating issues. Engine is quiet and smooth even in stop and go traffic during hot days.
I am running this oil in all the three holes as recommended by Amsoil. Gears are shifting great. I wish that I got this oil when the bike was new, which would have saved lots of engine wear. All my toys will get Amsoil!
