Extending the Life of Directhaul's Fleet
Directhaul is an Australian transportation company specialising in the transportation of dangerous goods. It operates a fleet of over 50 road-train rated prime movers. The fleet includes more than 200 trailers and dollies in Queensland and the Northern Territory. These are powered by Cummins and Volvo engines with both EGR and SCR exhaust systems. Internal fleet maintenance is carried out in Darwin, Townsville and Broome.
Our technical team worked hand-in-hand with Directhaul maintenance managers to increase engine life, reduce maintenance costs and increase reliability.
We recommended the use of Puma HD Ultra S 15W-40 oil and measured the impact through a number of trucks over a 12-month period. Both SCR exhaust systems with 500 hours drain interval and EGR exhaust systems with 250 hours drain interval were used.
We evaluated the performance of the engine oil by carrying out oil analysis using an independent oil analysis lab and comparing the results against the previous engine oil (15W-40 API CJ4 category oil). Puma HD Ultra S demonstrated significant wear reduction benefits for Directhaul trucks – an average of 18% less wear. This in turn directly improved engine life and enabled cost savings.
With the help of Puma Lubricants, Directhaul Australia has reduced engine wear, decreased maintenance cost, increased fleet availability and achieved extra cost savings estimated to be $48,000 a year*.
