A familiar sight on Ontario roadways for more than 50 years, the family-owned construction company Cox Construction has grown from a one-man shop with a single crusher to a 140-person operation capable of completing any size of road-building, crushing or paving project. A key factor in the company’s success has been its ability to find innovative ways to cut down on maintenance time and improve productivity.
Equipment maintenance is high on the company’s list of priorities. It keeps in good repair its fleet of over 200 pieces of mobile equipment, including earth movers, asphalt plants, crushers, generator sets and dump trucks. In addition, oil levels and lubricants are checked frequently. However, oil changes require taking equipment out of service, which means downtime for both equipment and personnel.
Cox started looking for an improved engine oil with significantly longer drain intervals than the lubricant it had been using. The company decided to test Petro-Canada’s Duron Synthetic heavy-duty engine oil in four of its Volvo dump trucks. These trucks, outfitted with Volvo VDE-12 engines–two 1996 models and two 1994 models, are used to haul loads of between 85,000 lb and 110,000 lb to and from its various construction projects throughout Ontario.
Regan Cox, vice-president, admits that at first he was cautious about testing a new product in his Volvo machinery. “We knew that testing the wrong engine oil could be catastrophic for our equipment,” says Cox. “But from our own experience and from listening to the experience of others, we felt that we could trust Petro-Canada. Ultimately, we would not have done the test unless we felt comfortable that this was the way for us to go.”
Using the Duron Synthetic oil, Cox achieved drain intervals of 950 hours for testing purposes, with a very acceptable oil analysis. This was in comparison to 250-hour drain intervals with the previous brand. “Longer drain intervals means keeping machinery working longer which means better efficiency for us,” says Cox. “It also means less time spent on maintenance, which again keeps the machinery working longer.”
For use in both mobile and stationary equipment in the trucking, construction, mining, forestry and manufacturing industries, Duron Synthetic is a full synthetic lubricant recently introduced by Petro-Canada to provide full synthetic performance at a lower cost. Rated as an SAE 5W-40 grade, it is blended both to handle extreme service applications and to provide excellent cold start-up capabilities. Product features include extended drain intervals, reduced engine wear properties and premium soot-handling capabilities. The lubricant has both Mack EO-M Plus and Cummins CES 20076 approvals. It is available in 205-l drums, 20-l pails, and 1-l and 4-l bottles.
