- Amsoil Best Synthetic Motor Oil for Harley-Davidson Motorcycles
Although Harley-Davidson Motorcycle Company routinely tells its customers they must use “Harley-specific” motor oils and lubes, some riders are realizing AMSOIL keeps the popular bikes running cooler and smoother.
- WHY HARLEY OWNERS CHOOSE AMSOIL BEST
The recent introduction of Screamin' Eagle® Synthetic Lubricant by Harley Davidson® indicates the Motor Company has finally recognized the benefits of running synthetic motorcycle oil in their air-cooled engines. After years of advising dealers and customers to avoid using synthetic oils in their bikes, it's natural to wonder why the company is suddenly marketing one.

AMSOIL Product Usage for Harley-Davidson Motorcycles
(Links Below Open in New Window)
For 883cc and 1200 Sportster motorcycles, the AMSOIL Synthetic 20W-50 Motorcycle Oil (Product
code MCVQT) is recommended for both the engine and the transmission.
On 1340 cc, 1450 cc and 1584cc models, the 20W-50 AMSOIL Synthetic Motorcycle Oil (Product
code MCVQT) is recommended for the engine crankcase, AMSOIL 75W-110 Gear Lube (Product
code SVTQT) for the transmission and AMSOIL 10W-40 (Product code MCFQT) Synthetic Motorcycle Oil for the chaincase.
These recommendations for the 1340 cc, 1450 cc, and 1584 cc are, in our opinion, superior to
using a 20W-50 m/c oil in the engine, transmission and primary as H-D recommends with their new Syn3. If you choose
to you certainly can use the AMSOIL 20W-50 motorcycle oil in the engine, transmission and primary as a
replacement for the Syn3 (which is a 20W-50 m/c oil), however it is our recommendation that it is better to use the
specific products outlined above for superior performance.
Gear Lubes have Extreme Pressure (EP) additives for superior protection of the gear surfaces while motor oils
typically do not have EP additives since EP additives can be detrimental inside an engine. Therefore it is better
to use gear lube in your transmission than motor oil.
The change interval specification on AMSOIL motorcycle oil and AMSOIL Super Motorcycle Oil Filters is 2 times manufacturer
If the transmission of your Harley clanks (which is a problem among many
Harley-Davidson Motorcycles) upon shifting gears when you accelerate, the AMSOIL 75W-110 Severe Gear Lube
(Product code SVTQT) will get rid of the transmission noise leading to smoother, noise free
