Let’s go further with Delo® Gold Ultra SAE 15W-40

When your heavy-duty equipment is working, your business is driving profits. At Caltex, the goal is to optimise your diesel engine performance – helping minimise operating costs and maximise equipment uptime. 

As your lubrication partner, Caltex strives to help keep your diesel equipment running reliably and efficiently in all kinds of operating conditions, including cold weather or extreme oil-drain intervals.

It understands the challenges facing diesel customers today and in the future: 

• Higher performing diesel engines coming to market

• Different types of diesel fuels

• Latest original equipment manufacturer (OEM) requirements and specifications

• Mixed diesel engine types and age of equipment

• Extending oil drain intervals

• Increasing engine durability

You can count on Caltex’s industry experience, technology leadership, and the Caltex Delo® family of premium products to help you stay ahead of these challenges and protect and maximise the life of your vehicles.

Reliability and Durability are the Priority

The company’s lubricants stand for one thing above all else: reliability. Properly lubricating the inside of a heavy-duty diesel engine requires more than just creating a protective film. Caltex’s premium formula Delo® Gold Ultra SAE 15W-40 provides excellent oxidation resistance, deposit and oil consumption control, and wear performance to protect against loss of engine performance and life. Delo® Gold Ultra SAE 15W-40 has been formulated with ISOSYN technology to specifically protect your diesel equipment and vehicles and reduce the need for multiple diesel engine oils. Delo’s industry-leading lubricants have logged billions of kilometres and countless hours, providing superior protection to diesel engine parts and maximising fuel efficiency so your vehicles and equipment can go further.

Delo® Gold Ultra SAE 15W-40 exceeds industry specifications and OEM performance. 

Delo® Gold Ultra SAE 15W-40 is a premium diesel engine oil formulated to provide excellent long-drain performance, superb engine life protection, and excellent everyday performance in all types of operations, including stop-and-go, long-haul, and high-stress operating conditions. Delo® Gold Ultra SAE 15W-40 has been specifically formulated to provide superb protection and performance in harsh operating conditions, regardless of the type of diesel engine (older or newer) or alternative fuel types. Its robust formulation is designed to operate in a wide range of conditions and climatic areas, helping to minimise the number of diesel engine oils required by customers.

Delo® Gold Ultra SAE 15W-40 delivers results, superb oxidation, and deposit control

The Komatsu Hot Tube and Pressure Differential Scanning Calorimeter (PDSC) tests are good indicators of an oil’s ability to resist oxidation in high temperature conditions that can result in viscosity increase, piston deposits and sludge formation. 

Komatsu Hot Tube Test 

This test is run at 290°C for 16 hours, at which point the deposits formed are measured against a pre-determined deposit scale to show how well oil resists or forms deposits. This helps relate to how well an oil will perform under severe high temperature operating conditions that the oil will experience.

Delo® Gold Ultra SAE 15W-40 was run in this test and produced excellent results, even when compared against competitor premium-tier heavy-duty engine oil formulations. These results indicate that Delo® Gold Ultra SAE 15W-40 provides excellent high temperature deposit control. 

Pressure Differential Scanning Calorimeter

The PDSC measures the thin-film oxidation resistance of engine oils at 210°C under dry air pressure of 100psi. The onset of oxidation is detected by heat produced from the reaction. Higher rates of oxidation can cause more piston deposits, resulting in ring sticking and bore polishing.

Delo® Gold Ultra SAE 15W-40 and competitor top-tier heavy-duty engine oils were run in this test and the results compared to each other. Delo® Gold Ultra SAE 15W-40 showed very good performance as compared to competitor products, highlighting its robust formulation.
