Q. I have a 2001 Ford F-350 Pickup with a Powerstroke Diesel with 7000 miles. I'm getting ready to change over to synthetic oil. What AMSOIL motor oil would you recommend to use?
A. AMSOIL Series 3000 5W30 Heavy Duty Diesel Oil is our premium top of the line product. While there are best uses for both our Series 3000 and our AMSOIL 15W40 Diesel and Marine Oil, Series 3000 is our recommendation for the Ford Powerstroke engine. It surpasses the API Energy Conserving Rating requirements designed to provide significant fuel savings. It has highly effective anti foam.
