We used fully synthetic 5W-30 Amsoil engine oil for this project because it offers superior protection for the various wear surfaces within the 6.0L Power Stroke. We also replaced the engine's antifreeze with the new Super Duty coolant from Be Cool. This coolant comes premixed and ready for use. It is compatible with all types of engine coolant, has a 267-degree boiling point and protects engines for up to 300,000 miles.
