Synthetic Blend Super HD 10W-40 CK-4 is a Low-SAPS, high performance heavy duty engine oil formulated to provide lubrication to modern, low emissions engines operating in moderate to severe conditions. It meets or exceeds nearly all the next generation OEM specifications including those from Ford, Cummins, Detroit Diesel, Mack, Volvo, Renault, Mercedes, MAN, Scania, and Deutz. Super HD CK-4 Synthetic Blend motor oil protects engines with Emission Controls, EGR engines, as well as older engines. It is even recommended by leading heavy equipment manufacturers such as John Deere, Kubota, Massey Ferguson, JJ Case, Allis Chalmers, and International Harvester. This ground breaking low-ash technology provides improved wear protection, deposit and soot control, and improves oil consumption by neutralizing combustion by-products that cause harmful deposits¹. Emission reduction systems such as DPFs (Diesel Particulate Filters) have shown increased productivity and extended catalyst life this all new technology.
