Customer Benefits

Reduced maintenance costs – Highly effective detergent additive system minimizes piston crown land deposits which can lead to damaging bore polishing. High base number minimizes corrosive wear in those areas where medium to high sulphur fuel is still encountered.

Maximizes engine life – Proven metallo-organic anti-wear additive system reduces wear in severe service by forming a protective layer on all metal contact surfaces. Wide-range SAE 10W-40 multigrade viscosity ensures reduced friction at start-up and maximum lubricity at high operating temperatures.

Long oil drain intervals – Exceptional high temperature stability minimizes degradation that leads to sludge formation and oil thickening, and provides extended oil drain capability. Provides efficient dispersion of soot particles offering filter plugging protection.

Low oil consumption – Highly shear-stable viscosity index improvers prevent oil flow through the piston rings by maintaining oil viscosity in the high temperature ring belt area, while special low volatility base fluids minimize evaporative oil loss.

Service Considerations

Many European diesel engine manufacturers recommend oil drain intervals of up to 100,000 – 150,000km where oils meeting ACEA E4 or appropriate OEM specifications are used. However, such extended oil drain intervals should only be applied where service conditions match ideal European duty cycles and fuel sulfur levels. In most areas in which Caltex brand products are sold this is unlikely.

The higher fuel consumption, higher fuel sulfur levels and more severe operating conditions (such as dustiness, higher loads, and rougher surfaces) generally encountered in these areas mandate, for all diesel engine oils, reduced service intervals versus those used in more ideal environments. If operators adjust drain intervals to compensate for these service factors, Delo Gold Ultra T SAE 10W-40 can deliver proportionate benefits in terms of lower maintenance and lower engine life cycle costs.

For vehicles fitted with exhaust clean up devices of the diesel particulate trap type, lubricants conforming to low-SAPS (sulfated ash, phosphorus and sulfur) requirements should be employed like Delo 400 MGX SAE 15W-40 or Delo 400 SDE SAE 15W-40.
