Why Choose DURON?

Engine Protection & Durability

DURON is our most durable oil to meet the new category demands of API CK-4 and FA-4.

Surpassing the conditions of the Cummins ISB test, widely considered "one of the toughest engine performance tests," DURON next generation provides high levels of engine protection to extend the life of your engines.

Extended Drain Intervals

The longer your vehicles and equipment can go between oil drains, the better for your operations – and the lower your total lubricant costs will be.

The extreme durability of DURON next generation means you can stretch drain intervals with no compromise on reliability or engine protection.[1]

Extreme Operations

Temperature extremes are a big challenge for oil performance. Extreme high temperatures weaken and degrade ordinary engine oils and chilling temperatures impede oil flow.

Petro-Canada Lubricants are leaders in all season engine oils – and DURON next generation delivers performance you can trust.

Fuel Economy

On and off-road, fuel consumption is a critical cost for every heavy duty business.

In meeting the category demands of API CK-4 and FA-4, DURON next generation will have lower viscosity engine oils.

They can help to reduce the amount of viscous drag from the oil in the engine, allowing them to run more efficiently and potentially use less fuel.
