Caltex has announced it is responding to the challenge that rising expectations of cost and environmental performance are imposing on truck engine technology and lubricant requirements, particularly as stricter emissions standards start to present new maintenance challenges for the heavy vehicle industry.
The company claims that scientific testing shows engine lubricants are the primary source of ash build-up in diesel particular filters (DPF), and that this accounts for approximately 90 per cent of ash sources in the engine.
The company claims that ash clogging in the diesel particulate filters leads to reduced engine efficiency, increased fuel consumption, reduced fuel economy and higher maintenance costs and downtime over the life of the engine.
The company says it is responding to the challenge with its Delo 600 ADF with Omnimax engine oil, which it says is a premium, ultra-low ash synthetic oil that it says is formulated to improve fuel economy and reduce emissions.
David Sawyer, the manager for B2B fuels and lubricants at Caltex claims that its Delo 600 ADF with Ominax is a game-changer.
“Delo features an ultra-low 0.4 per cent sulphated ash content that minimises DPF clogging and cuts down metallic residue by up to 60 per cent,” Sawyer said.
“It also includes a powerful antioxidant system that prevents oil breakdown at high temperatures, enhancing oil longevity and reducing maintenance costs.”
The company claims that maintaining optimal fuel efficiency delivers significant cost savings throughout the life of the engine, and importantly in today’s climate – helps operators to meet the community’s expectations in terms of operating in a more efficient and sustainable manner.
The Australian Government Department of Climate Change, Energy, the Environment and Water estimates that the transport sector made up 19% of Australia’s emissions in 2022. Without intervention, it’s estimated transport will be Australia’s largest source of emissions by 2030.
“We know that the heavy transport industry is looking for opportunities to reduce fuel consumption and make their fleet cleaner, more efficient and cost-effective to run,” David said.
“The low metallic ash formulation of Delo 600 ADF actually boosts fuel efficiency by up to 3% thanks to reduced engine backpressure from minimal ash accumulation and more efficient regeneration,” explained David.
The company claims that its testing indicates that its Delo 600 ADF “ engine oil increases DPF maintenance intervals by up to 2.5 times as a result of the claimed reduction in DPF clogging,whi9ch it says helps to minimise service costs and equipment downtime.
The company says that Delo 600 ADF is backed by Chevron, which owns the Caltex brand globally which has had a presence in Australia for more than 70 years.
