Question: I just read about the new 4-stroke oil. I just bought a 2000 Suzuki Savage 650 and want to change it over to AMSOIL. I have been debating on which oil to use in it and was wondering if the new 4-stroke oil would work the best. My bike is a big single cylinder. It has 3k miles on it. I ride in Utah at 4-6k feet above sea level. Also, the bike has a wet clutch on it. Please let me know what you would recommend that would work best for my application.
Answer: Although the AMSOIL 4-stroke Oil would provide excellent performance in this application, the recommended motor oil is the AMSOIL Synthetic 10W-40 Motorcycle Oil. This lubricant is formulated specifically for motorcycles and is wet clutch-compatible.
