Lucas Oil Synthetic SAE 5W-40 CJ-4/SM Motor Oil, 1 Gallon (4 GAL / CS)

Lucas Synthetic SAE 5W-40 CJ-4 Truck Oil is designed for extreme cold weather applications but has all the protection and longevity of our SAE 15W-40 Synthetic CJ-4. It is blended with premium synthetic base oils and Lucas additives that help maintain the life of the emission control system as required for regulatory compliance. Expect less oil consumption and reduced engine wear. It resists oxidation and thermal breakdown for total protection in new and older engines. It provides increased lubricity, lowers oil temperature, reduces engine noise, increases oil pressure, and reduces soot levels. It is designed for diesels but itÆs perfectly suitable for gasoline engines. Lasts up to twice as long as ordinary 5W-40 engine oils.
