Our family have been loyal users and believers of AMSOIL synthetic lubricants for over 40 years. We’ve always had complete trust in the products and slept soundly at night knowing that our vehicles had the finest protection available. My grandfather always had AMSOIL in his cars and easily was able to get over 300,000 miles out of his vehicles.

When it came to lubricating the diesel engine in his self-made 38-foot sailboat, the only oil he considered to protect it was AMSOIL’s SAE 15W40 Heavy Duty Diesel and Marine Oil. The fact that it took him 10 years to build this sailboat from blueprints, he was not going to take any chance on lubricating the motor with an inferior oil.
