POWER DRIVEN DIESEL 15W-40 is a premium high performance diesel engine oil boosted with high levels of ZDDP to provide critical protection for performance turbo diesel engines. This premium CI-4 PLUS based oil is not a CJ-4 formulation. The CJ-4 classification was designed to meet government regulations mandating long service life for emissions components. To meet these demands, the ZDDP content of CJ-4 oils was reduced significantly: this is great for catalytic converters, not for performance diesel engines. Many diesels never came with catalytic converters or diesel particulate filters, these engines should not be forced to run inferior oil products. ZDDP is the best anti-wear additive available. POWER DRIVEN DIESEL 15W-40 oil boosted with ZDDP is based on a CI-4 PLUS formulation combined with our proprietary performance additive package. It is engineered to provide diesel engines the best anti-wear protection available under all conditions.
THIS PRODUCT IS NOT RECOMMENDED FOR VEHICLES WITH CATALYTIC CONVERTERS OR DIESEL PARTICULATE FILTERS AS THE CONCENTRATED ANTI-WEAR FORMULATION MAY DAMAGE EMISSION SYSTEM COMPONENTS.
