Caltex and DP World had the opportunity to tear down one of the terminal tractor trucks that operate on a Cummins engine and inspected its parts for wear and deposit control performance. The results were astounding, after 57,000 hours in severe service operation, the engine parts were in very good condition which reinforced  the excellent performance provided by Delo Gold Ultra in helping DP World achieve its tractor reliability goals.

The current bench tests like the Komatsu Hot Tube (KHT) and The Pressure Differential Scanning Calorimeter (PDSC) have been good screeners for lubricants.

Komatsu Hot Tube (KHT) show how well the oil’s capability to resist oxidation in high conditions or forms deposits under severe high temperatures at 290°C for 16 hours. While The Pressure Differential Scanning Calorimeter (PDSC) test measured the thin-film oxidation resistance of engine oils at 210ºC under dry air pressure of 100 psi which showed better performance compared to other competitor products.
