Diesel oil is undergoing a major change. Federal regulations dictate that medium- and heavy-duty diesel vehicles must reduce fuel consumption and greenhouse gas emissions 15 percent by model year 2018, driving changes to diesel technology. The new API CK-4 and FA-4 diesel oil specifications address these changes, and the overhauled AMSOIL synthetic diesel oil lineup brings even better protection and performance with it.
New AMSOIL Signature Series Max-Duty Synthetic Diesel Oil replaces AMSOIL Premium Synthetic Diesel Oil. New AMSOIL Heavy-Duty Synthetic Diesel Oil replaces AMSOIL OE Synthetic Diesel Oil.
