More durable oil means better sustained protection to extend the life of your engines.
DURON is so durable it surpasses the passing conditions of the Cummins ISB API CK-4 and FA-4 qualification test, widely considered "one of the toughest engine performance tests."
The longer you can safely extend oil drain intervals, the better your productivity. DURON has proven time and time again to enable vehicles and equipment to go further between oil drains with no compromise on reliability or engine protection.
When conditions are extreme, that’s when you need to trust your oil most. High temperatures can degrade ordinary engine oils and freezing temperatures impede oil flow. DURON performs in some of the most extreme environments in the world.
Petro-Canada Lubricants are leaders in all season engine oils – and DURON delivers performance you can trust.
On and off-road, fuel consumption is a critical cost for every heavy-duty business.
In meeting the category demands of API CK-4 or FA-4, DURON delivers outstanding protection with lower viscosity engine oils, allowing engines to run more efficiently and potentially use less fuel.
