Going further with Delo Gold Ultra

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

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

It understands the current and future challenges facing diesel consumers, including higher-performing diesel engines coming to market, different types of diesel fuels, the latest original equipment manufacturer (OEM) requirements and specifications, mixed diesel engine types and age of equipment, extending oil drain intervals, and 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

Caltex 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. It 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 and age of diesel engine, 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 exceeds most industry and engine manufacturers’ performance requirements, including ACEA E7; API CI-4 and CH-4 / SL; Caterpillar ECF-1-a; Cummins CES 20078, 77, and 76; Daimler MB Approval 228.3; Mack EO-O Premium Plus; MAN M 3275-1; MTU Category 2; Renault RLD-2; and Volvo VDS-3.

It also meets the requirements of ACEA E5-02; API CF-4, CF, and CD; Cummins CES 20072 and 20071; JASO DH-1; and Mack EO-M Plus. Furthermore, Delo® Gold Ultra SAE 15W-40 delivers results, superb oxidation and deposit control. 

Komatsu hot tube test

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

Delo® Gold Ultra SAE 15W-40 was run in this test and showed 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 (PDSC)

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 oxidations 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. When the results were compared, Delo® Gold Ultra SAE 15W-40 displayed very good performance, highlighting its robust formulation.
