Why Should you use AMSOIL Lubricants?
As a leader in synthetic lubricant development, AMSOIL is dedicated to finding new ways to address the most pressing issues that vehicles and equipment face. AMSOIL synthetic lubricants’ outstanding performance in a variety of markets, including automotive, powersports, industrial, and racing, has given us an unmistakable presence in the industry and earned us widespread esteem for our brand. We’ve gained a devoted following thanks to our relentless pursuit of cutting-edge technology.
What is Synthetic Oil? In order to create pure lubricants, AMSOIL uses synthetic lubricants that are chemically engineered. For the most part, they don’t contain any unwanted substances or molecules. Their versatility and pure, uniform molecular structures give them properties that conventional lubricants simply can’t match when it comes to friction reduction, fuel efficiency, film strength, or extreme temperature performance.
On the other hand, conventional lubricant is refined out of crude oil. Sulfur, nitrogen, oxygen, and metal components such as nickel or vanadium are all present in crude oil and cannot be removed during refining to remove these contaminants completely.. By separating the various types of molecules in the oil based on weight, the oil refining process reduces the oil’s performance.
