• 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. It is recommended that you use either AMSOIL Series 3000 Synthetic 5W-30 Heavy-Duty Diesel Oil (HDD) or AMSOIL Synthetic 15W-40 Heavy-Duty Diesel and Marine Motor Oil (AME) for this diesel application. HDD is the preferred choice for better fuel economy, cold weather performance and mixed gasoline and diesel engine fleets. It provides better protection compared to conventional 15W-40 mineral based oils with its superior film strength and enhanced anti-wear additives. AMSOIL AME is a premium oil that matches many manufacturers viscosity recommendations. It outperforms competitive 15W-40 oils and is a lower cost option compared to AMSOIL HDD.
