There is so much data out there about the AMSOIL 20W-50 V-Twin Motorcycle Oil that you don’t have to look far to know why so many people swear by it but when we opened the Sioux Falls store, it’s use was low here compared to other cities simply due to supply.. But now we have solved that problem!! We keep more than enough in inventory so stop in and discover at the first twist of the throttle why AMSOIL’s 20W-50 is superior.

Amsoil 20W-50 motorcycle oil Viscosity and Oxidation tests

Withstands Extreme Heat

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 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. AMSOIL Synthetic V-Twin Motorcycle Oil is extremely resistant to breakdown and engineered to prevent damaging sludge and carbon deposits for superior engine cleanliness.

Provides Extreme-Pressure Quality 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 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.

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

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.

*All trademarked names and images are the property of their respective owners and may be registered marks in some countries. No affiliation or endorsement claim, express or implied, is made by their use. All products advertised here are AMSOIL-engineered for use in the applications shown.

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.

WARRANTY SECURE™

AMSOIL 20W-50 Synthetic V-Twin Motorcycle Oil is Warranty Secure, keeping your factory warranty intact. AMSOIL 20W-50 Synthetic V-Twin Motorcycle Oil is a high-performance replacement for vehicle manufacturer-branded products and is also backed by the AMSOIL Limited Warranty.

AMSOIL Direct Jobber Note:
There is a reason the AMSOIL Motorcycle Oils can lead the industry. There are several reasons actually. The larger corporate firms can produce an oil of this merit but their methods are quite different when it comes to how they can out source for the best additives. It also has a lot to do with years in the business and the ability to make certain things work. Even the issue of access to data.
But other companies do have to make a profit for stockholders (which AMSOIL does not have) and their products have to be ideal for central distribution to merchants. Other OEM labels are simple existing products re-labeled to market to a group willing to pay more but the core issue is that if any single company was to duplicate the process and end-product quality that AMSOIL offers, that quart of oil would need to be marked up at least 60% higher than AMSOIL’s full retail currently.  That’s the only way the better product could keep the profit margins the same all around for everybody.

Peace of mind

I used Amsoil 20W50 V-Twin motorcycle oil for over 80,000 miles in my 2005 Harley and it was still running strong at 120,000 when I traded up to a 2016 Harley. I specified Amsoil at the 500 mile service and have rolled up 13,000 trouble free miles already. Looking forward to another 100,000.

Excellent Product.

After breakin on my new rebuild stroker evo, I added this 20W-50 synthetic V-twin oil. Then set out for 5,380 mile road trip, 2 up in mostly 90-100+ F heat. Total oil added was less than 2 oz! No heating issues! Very impressed with this product.

You Just Can’t Beat Quality

I use AMSOIL products in the Engine, Transmission and Primary case of all the Harley-Davidson motorcycles I’ve owned since I started riding after a 40 year hiatus in 2012.

I have also used AMSOIL in all of my air cooled Volkswagen powered vehicles for decades. You can’t beat it’s quality. The fact AMSOIL sells application specific lubricants that really ARE superior to “universal” lubricants is a HUGE plus too.

8yrs of Arizona punishment
By Ron 12/13/2016

Pro Atv Desert racer been running 20-50 now for the last 8yrs changing the oil after 2 races which average a couple hundred miles each and a few hrs of brutal punishment and harsh Arizona desert summer temps I replace the cylinder and piston at the end of Every season after over a 1000 miles and over a hundred total hrs in a season the piston and cylinder look as if they did when I installed them, the last 8yrs I have not had any engine failures of any sort and it’s because of AMSOIL synthetics. I’ve seen so many guys I race with blow there engines time and time again during the season and they continue using their own preferences of oils and still have issues. I have so much confidence in AMSOIL when going racing that engine failures don’t even cross my mind………thank you AMSOIL for your continued sponsorship support and your hard work put in by your R&D department…….It’s paying off…..”!!!!!
