AMSOIL synthetic lubricants deliver wear protection, engine cleanliness and fuel efficiency conventional oils simply can't match. Although you might know that synthetic oils outperform conventional oils, you might not understand why. Our products are put to the test in the lab, on the track and in the streets.

What Is 20W-50 Oil Used For? 20W-50 is a common motor oil used in moderate-to-large diesel and gasoline engines, high-performance motorcycle bikes, and aviation vehicles. Its resistance to thinning at high heat also makes it popular as a racing oil and high temperature driving.

AMSOIL Synthetic Advanced Formula SAE 10W-30 (MCT) and SAE 10W-40 Motorcycle Oil (MCF) are recommended for liquid or air-cooled 4-stroke engines. It meets SAE 80W/90, API GL-1 gear oil requirements and is recommended for transmissions on both 4- and 2-stroke motorcycles.

Mobil 1 V-Twin 20W-50 motorcycle oil combines high-performance synthetic base stocks technology with a precisely balanced component system to help provide outstanding engine cleanliness, excellent wear protection at high temperatures and highly effective protection from corrosion.

Not only does AMSOIL exceed industry standards and outperform competing brands, it fights viscosity breakdown 46% better than Mobil 1. It's built to stand up to the devastating effects of high-horsepower, modern engines and provide maximum protection.

AMSOIL motor oils are designed to deliver enhanced performance and extended drain intervals, justifying any higher price. AMSOIL offers premium products that rightfully command a premium price. Like anything of real value, however, the true consumer cost doesn't end with the purchase price.

Helps extend engine life for over 50 years. It has evolved to meet the needs of consumers and auto manufacturers since 1968 and continues to innovate and remain a trusted brand today.

The "20W" indicates its viscosity at colder temperatures, offering good flow during startup. The "50" denotes its viscosity at higher temperatures, providing adequate lubrication under extreme conditions. It is suitable for engines operating in hot climates or those subject to heavy loads and high temperatures.

Motorcycles use V-twin engines because they fit in the frames really well. they are narrow, so the bike can have a slim profile, the seat can be taller so the rider's legs have a more direct path to the ground than with wider 4 cylinder engines.

AMSOIL's premium synthetic lubricants provide several benefits, including:

• Improved fuel efficiency.
• Extended equipment life.
• Lower operating costs.
• Improved performance and protection in extreme temperature conditions.
• Environmentally-friendly solutions.

AMSOIL synthetic motor oil uses naturally shear-resistant base oils combined with top-tier, shear-stable viscosity improvers that withstand extreme heat and shearing forces. Not only does AMSOIL exceed industry standards and outperform competing brands, it fights viscosity breakdown 46% better than Mobil 1.
