The approval follows extended field testing across multiple engine platforms. Duron Advanced 5W-30 is now cleared for use in Volvo 13L Euro 6 Step D engines and 2021-and-newer Mack MP8 engines.
“These OEM approvals reflect the strength of our technology and development teams,” said Melissa Mastrocola, business segment manager for transportation at Petro-Canada Lubricants, in a release..
“Few fluids today are recommended for these modern engines, which underscores the quality of this product.”
