PRO-SPEC IV HD SYNTHETIC engine oil is a 5W/40 engine oil formulated with synthetic base oils to protect on-highway and off-highway diesel engines operating in a wide range of temperatures and under severe conditions that require a CJ-4 engine oil. Treat your equipment with the protection it deserves, by providing it with an engine oil designed to get your equipment the extra mile.
Most wear that is experienced on engines occurs during a cold start-up because of the lack of lubrication on the internal parts. PRO-SPEC IV HD SYNTHETIC contains synthetic base stocks that significantly increase the cold flow of the engine oil at start-up. The use of synthetic base stocks results in a higher Viscosity Index and a fluid that is resistant to viscosity change at any temperature, keeping the internal components of the engine lubricated and protected.
Unparalleled Savings
PRO-SPEC IV HD SYNTHETIC is formulated with an industry leading Base Number (BN) of 15 and contains a BN retention package that helps extend the drain intervals of the engine oil. It has been found through testing, that engines using PRO-SPEC IV HD SYNTHETIC experienced an increase in fuel economy of 1-3 % when compared to conventional 15W/40 CJ-4 engine oils. Extended drain intervals and savings in fuel economy allow customers to experience exceptional savings when they switch to PRO-SPEC IV HD SYNTHETIC.
Resists Oxidation
Oxidation is the most common contributing factor to a reduction in life for an engine oil. The acidification and thickening of engine oil during the oxidation process can only be combated by a robust additive package containing strong acid neutralizers and detergents to eliminate deposit build-ups. PRO-SPEC IV HD SYNTHETIC attacks acids in the engine oil, thereby extending the drain intervals of the engine oil.
