What We Learned After Putting More than 200,000 Miles on this Harley
We Put More than 200,000 Miles on this HarleyHarley
At AMSOIL, we go the extra mile when it comes to product testing. In the case of our 2012 Harley-Davidson, we went 207,111 miles.
Since arriving at the AMSOIL mechanical lab in March 2015, the bike has been a fixture on the SuperFlow CycleDyn engine dynamometer. It has served as the proving grounds for several different motorcycle oil formulations. After several rounds of testing spanning more than two years, here are the highlights of the bike’s eventful service life.
THE MOTORCYCLE
2012 Harley-Davidson FXDB Dyna* Street Bob*
1584-cc engine
THE TESTING
All totaled, 14 different tests were run using the Harley. Their purpose was typically to test candidate motorcycle oil formulations with the goal of constantly improving the final product available to customers.
To do that, AMSOIL engineers designed a 250-hour (about 14,000 miles) test designed to create a motorcycle oil’s biggest enemy – heat. The computer-controlled engine dyno is programmed to hold the bike at a steady 55 mph, alternating between low-torque (25 ft. lbs.) and high-torque (57 ft. lbs.) conditions to simulate highway cruising punctuated by periods of hill climbing. A 25-hp fan directs air over the engine, simulating airflow at highway speeds.
Early on, engineers discovered that the rear cylinder was abnormally hot compared to the front. It turned out lack of airflow was to blame. When a rider is sitting on the bike, his or her legs deflect cooling air over the rear cylinder. To recreate this scenario, a metal shield was constructed that mimics the effect of someone sitting on the bike, resulting in accurate rear-cylinder temperatures.
After each test, the engine is disassembled and examined for wear, deposits, varnish and other distress. Each engine part is documented, photographed and archived. Then, to ensure accurate future test results, the engine is reassembled using fresh parts for the next round of testing.
250-HOUR TEST BY THE NUMBERS

Just one of the 26 pistons run through the Harley. After 250 hours in high-heat conditions, the skirt still looks great, with no scuffing or wear.

FAQS: Motorcycles
What AMSOIL motor oils are recommended for Harley-Davidson motorcycles?
Answer: AMSOIL 20W-50 Synthetic Motorcycle Oil and SAE 60 Synthetic Motorcycle Oil are the most commonly recommended oils for Harley-Davidson applications. Check the AMSOIL Motorcycle Product Lookup for specific recommendations.
_____________________________________________________________________________________________________________________________________________________
What is the difference between Formula 4-Stroke® 10W-40 Synthetic Scooter Oil and 10W-40 Synthetic Motorcycle Oil?
Answer: AMSOIL 10W-40 Synthetic Motorcycle Oil contains a robust additive package designed for the extreme pressures and high temperatures common in motorcycle applications. Its high TBN retention also makes it the appropriate choice for extended drain intervals. In scooter applications, Formula 4-Stroke 10W-40 Synthetic Scooter Oil is the more economical choice.
_____________________________________________________________________________________________________________________________________________________
What are the recommended AMSOIL transmission and primary chaincase lubricants for a Harley-Davidson Big Twin?
Answer: For the newer Big Twins, AMSOIL recommends 20W- 50 Synthetic Motorcycle Oil (MCV) in the engine, transmission and primary chaincase. As secondary recommendations, Synthetic V-Twin Transmission Fluid (MVT) may be used in the transmission, and Synthetic V-Twin Primary Fluid (MVP) may be used in the primary chaincase. In older Harleys such as Knuckleheads, Panheads and Shovelheads, AMSOIL recommends SAE 60 Synthetic Motorcycle Oil (MCS).
_____________________________________________________________________________________________________________________________________________________
What is the recommended AMSOIL transmission and primary chaincase lubricant for a Harley-Davidson Sportster?
Answer: AMSOIL recommends 20W-50 Synthetic Motorcycle Oil (MCV) for Harley-Davidson Sportster engines, transmissions and primary chaincases.
_____________________________________________________________________________________________________________________________________________________
Are AMSOIL synthetic motorcycle oils wet-clutch compatible?
Answer: Yes. AMSOIL synthetic motorcycle oils meet JASO MA2 friction requirements for use in wet-clutch applications.
_____________________________________________________________________________________________________________________________________________________
Is AMSOIL Synthetic Chaincase & Gear Oil (TCC) acceptable to use in the primary chaincase of a Harley-Davidson Big Twin?
Answer: AMSOIL Synthetic Chaincase & Gear Oil does not have the correct viscosity for use in Harley-Davidson primary chaincases, and is not recommended for these applications. AMSOIL 20W-50 Synthetic Motorcycle Oil (MCV) is the primary recommendation for Harley- Davidson primary chaincases. The secondary recommendation is AMSOIL Synthetic V-Twin Primary Fluid (MVP).
_____________________________________________________________________________________________________________________________________________________
How can AMSOIL recommend 20W-50 Synthetic Motorcycle Oil for use in the primary chaincases and transmissions of certain motorcycles?Answer: AMSOIL 20W-50 Synthetic Motorcycle Oil is engineered with premium additive packages specifically designed to provide high performance in motorcycle engines, transmissions and primary chaincases. However, if a customer does not want to use it in all three sumps, AMSOIL Synthetic V-Twin Transmission Fluid (MVT) and Synthetic V-Twin Primary Fluid (MVP) are secondary recommendations.
_____________________________________________________________________________________________________________________________________________________
What is the recommended AMSOIL lubricant for Victory and 2013 and newer Indian motorcycles?
Answer: AMSOIL recommends 20W-40 Synthetic V-Twin Motorcycle Oil (MVI) for all Victory and 2013 and newer Indian motorcycles, excluding the Scout (which requires 15W-60 engine oil).What is the oil change interval for AMSOIL synthetic motorcycle oils?
Answer: AMSOIL synthetic motorcycle oils are engineered to provide outstanding protection for up to twice the manufacturer’s recommended change interval or one year, whichever comes first. Unless using an AMSOIL Ea Motorcycle Oil Filter, change the filter based on the manufacturer’s recommended interval. For Big Twin Harley-Davidson transmissions, follow the Harley-Davidson recommended drain interval for synthetic oil up to 20,000 miles or one year, whichever comes first.
_____________________________________________________________________________________________________________________________________________________
Are AMSOIL synthetic motorcycle oils different from AMSOIL synthetic automotive oils?
Answer: Yes. In addition to different additive packages, withstanding extreme pressure, protecting against rust and withstanding high temperatures, motorcycle oils must be compatible with wet clutches. AMSOIL synthetic motorcycle oils are designed to meet the unique frictional requirements necessary for wet-clutch compatibility and provide maximum protection and performance in these applications.
_____________________________________________________________________________________________________________________________________________________
Why does AMSOIL offer more than one viscosity motorcycle oil?
Answer: AMSOIL offers motorcycle oils in different viscosities to accommodate the differences between motorcycle models and manufacturers. Just as in automotive applications, motorcycle engines require specific oil viscosities for optimal performance and protection based on the components and tolerances in the engine. Check the AMSOIL Motorcycle Product Lookup for specific recommendations.
