TRUCK FLEET CK4 OIL

Engine Oil combines premium base stocks with next-generation additive technology to produce our most fuel-efficient cleanest burning, low-ash heavy duty engine oil to date. 

15w/40 CK4 Synthetic Blend is formulated with the use of Eco Friendly, Low Ash additive technology to provide robust protection with increased fuel economy in on and off-road heavy-duty engines. It meets or exceeds nearly all of the next generation OEM specifications including those from Ford, Caterpillar, Cummins, Detroit Diesel, Mack, Volvo, Renault, Mercedes, MAN and Deutz.

15w/40 CK4 Synthetic Blend motor oils protect engines with Emission Controls, ECR engines, as well as older engines. This advanced additive technology provides improved wear protection, deposit and soot control, and improves oil consumption by neutralizing ash forming combustion by-products that cause harmful deposits. 15w/40 CK4 Synthetic Blend is an extended drain capable motor oil that prevents viscosity loss from shearing and reduces friction leading to longer engine life and improved fuel economy. Its high film strength makes 15w/40 CK4 Synthetic Blend is suitable for both on and offroad, severe service driving conditions. It can be recommended for new engines requiring CK4 fluid and is backward compatible with API CJ-4, Cl-4 PLUS, Cl-4, and CH oils.
