Construction Equipment and Petro Canada Duron Heavy Duty Engine Oils

Take a moment and compare the vehicle you’re currently driving to the one in which you learned how to drive. Even if it’s only been a few years since you first depressed the accelerator, there have been profound changes in the design and operation of vehicles. Some changes are more about convenience — from pushbutton ignition to Bluetooth connections — but most of the profound changes have taken place with engines and the other components that keep you on the road. From computer controls to more sophisticated power transmission, today’s vehicles are more powerful and efficient than those from even a decade ago.

The same thing has happened in the construction industry. The dozers, excavators, graders, and other familiar pieces of equipment look very similar, but when you start to take them apart, you’ll see that they have little in common with the workhorses that remained much the same for decades. As with your vehicle, these changes have increased power, improved efficiency, and added to the reliability for construction operators — but just as the “shadetree mechanic” has become a thing of the past, their sophistication has made maintenance more challenging.


You may think of construction vehicles as rough-and-tumble equipment, but today’s models are remarkably sophisticated, high-tech marvels that depend as much on GPS and other technologies as on the operators’ skills.

As OEMs have used innovation to pump extra horsepower out of every cylinder, the tolerances have narrowed. That means tougher specifications and more precise lubricant choices. In the old days, an OEM may have simply specified a particular weight. Today, they’re issuing requirements for everything from viscosity to particulate matter, citing specific API and ISO standards.

It makes sense, because higher-quality lubricants stand up to more. In addition to operating in all sorts of weather, today’s construction equipment uses engines that experience brutal operating temperatures that can exceed 900°F. Whether it’s bathing the crankcase, powering a hydraulic cylinder, or smoothing some point where two pieces of metal pivot, that thin coating of lubricant is what keeps friction from interfering with productivity and controls the temperatures. Using the best-quality lubricants means fewer breakdowns and longer service cycles.



DURON next generation engine oils outperformed both the API CK-4 and FA-4 specifications and the previous generation DURON line across a number of the toughest durability tests tied to oxidation control, shear stability, and aeration control. The core technology in these engine oils controls cylinder and bearing wear beyond industry and OEM standards.

For example, DURON SHP is one of the most durable heavy duty diesel engine oils Petro-Canada has ever created, meeting the exacting API CK-4 demands. DURON UHP 10W-40 engine oil is made with a synthetic base stock and high-performance additives, delivering exceptional wear protection and extending drain intervals, even when equipment operates under maximum load conditions.
