Shell Lubricants' Shell Rotella Ultra ELC is a heavy duty engine antifreeze/coolant product for use in heavy duty diesel, gasoline and natural gas-powered engines. It is an improved performance, next-generation, extended-life engine coolant that is designed to meet the more severe operating conditions of new emission-compliant engines, says the company. It is the most technologically advanced coolant offered by the Shell Rotella brand. The Rotella Ultra ELC is joined in Shell’s heavy duty coolants line by Rotella Fully Formulated, which has replaced Diesel Ready Fully Formulated Coolant/Antifreeze and Rotella ELC.
