Next-Level Protection: Caltex Delo® 600 ADF

Caltex Delo® is a game-changer for fuel efficiency.

Rising expectations on cost and environmental performance are transforming engine technology and lubricant requirements, as stricter emissions standards present new maintenance challenges for the heavy vehicle industry.

Scientific testing shows engine lubricants are the primary source of ash build-up in the diesel particular filter (DPF), accounting for approximately 90% of ash sources. Ash clogging in the DPF leads to reduced engine efficiency, increased fuel consumption, reduced fuel economy and higher maintenance costs and downtime over the engine's life.

Caltex Australia is responding to the challenge with its Delo® 600 ADF with OMNIMAX™ engine oil, a premium, high-performance “ultra-low ash” synthetic technology oil formulated to improve fuel economy and reduce emissions more efficiently and sustainably. David Sawyer , Manager of B2B Fuels and Lubricants for Caltex said Delo® 600 ADF with OMINAX™ was a game-changer.“

"Delo® features an ultra-low 0.4% sulphated ash content that minimises DPF clogging and cuts down metallic residue by up to 60%,” David said.

“It also includes a powerful antioxidant system that prevents oil breakdown at high temperatures, enhancing oil longevity and reducing maintenance costs.”

Maintaining optimal fuel efficiency delivers significant cost savings throughout the engine's life, and importantly in today’s climate – helps operators meet the community’s expectations in terms of operating more efficiently and sustainably.

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 boosts fuel efficiency by up to 3% thanks to reduced engine backpressure from minimal ash accumulation and more efficient regeneration,” explained David.

Testing indicates that the Delo® 600 ADF “ultra-low ash” diesel engine oil increases DPF maintenance intervals by up to 2.5 times through a reduction in DPF clogging, helping to minimise service costs and equipment downtime.

Delo® 600 ADF significantly outperformed in engine durability tests, with a 94% better deposit rating on the Industry Standard Piston Deposit Test compared with ACEA E9 lubricants, and no cam wear in the Industry Standard Cam Wear Test. Delo® 600 ADF is backed by Chevron, one of the largest and most innovative integrated energy companies in the world. Chevron owns the Caltex brand globally and is proud of its presence in Australia for more than 70 years.
