Petro-Canada’s DURON™ line of premium performance multi-grade diesel engine oils delivers industry leading protection against increased wear which can lead to lower productivity and impaired fuel economy. They’re formulated to exceed API CK-4 specifications and are suitable for use in the latest 2017 EPA compliant low emission engines which employ advanced exhaust after treatment devices.
DURON UHP 5W-40 is an Ultra High Performance full synthetic heavy duty engine oil that provides excellent protection and performance, especially in low temperature environments. It helps conserve energy and reduces engine wear through ease of cold weather start-up and lower viscous drag.
