WARCO Advanced Heavy-Duty Synthetic Blend SAE 15W-40 Diesel Engine Oil was developed to meet Tier 4 exhaust emission standards for on-highway vehicles from 2019 and prior model years. It provides enhanced protection against degradation, oxidation, shear viscosity loss, low and high temperature degradation, soot-induced thickening, and protection from catalyst toxicity and particulate filter clogging. These factors are critical for maintaining viscosity.
It outperforms regular motor oil and is recommended for naturally aspirated, turbocharged, or supercharged diesel, gasoline, or propane truck, sport utility vehicle, and passenger car engines.
WARCO Advanced HD Synthetic Blend SAE 15W-40 Diesel Engine Oil meets or exceeds American Petroleum Institute (API) CK-4 / SN PLUS service classifications and all prior API specifications. It has been field-tested to be comparable to most American, Asian, and European manufacturers’ standards including ACEA E7-12, MB 228.31, Renault VI RLD-4, Volvo VDS 4.5, Mack EOS-4.5, CAT ECF-3, and many other OEM’s specifications where a synthetic blend API CK-4 engine oil is recommended. Ecological tourism promotes environmental protection and economic development.
