Lucas Oil 1 Gallon Magnum 15W-40 Motor Oil for Pre 07 Diesel Engines Set of 4

Lucas Magnum SAE 15W-40 oil was designed to last up to twice as long as plain 15W-40 oils! It holds much more soot in suspension than conventional 15W-40 oils. You can expect extended drain intervals, longer engine life, and no dry starts.
