Synthetic Oil Vs. Conventional
Conventional oil is laden with natural impurities and irregularities, impurities that reduce efficiency and place a limit on performance. Synthetic oil is pure, free from these natural limits that regular oil faces. They have a uniform molecular structure that impart properties that provide wear protection, extreme-temperature performance, and fuel efficiency that conventional lubricants just can’t touch.
The Synthetic Oil Advantage
We are heavily invested in product research and testing; remaining at the forefront of the industry is the company’s first priority. All of the money and time AMSOIL spends in labs and on test tracks is for one purpose: to guarantee every motor that uses our synthetic oil has the cutting-edge synthetic technology it needs to operate at maximum efficiency.
