• Six months after Shell Care advised Denby Transport not to replace the engines in three D-registered tractive units — even though they had covered more than 480,000km (300,000 miles) each — the vehicles are still running without any mechanical problems.
When deciding which of the three tractive units' engines to replace Denby sent engine oil samples to a Shell Care laboratory. The lab report said that all the engines were sound and advised Denby to continue running them.
Denby has used Shell Care for four years; it sends engine oil samples from its 28 vehicles to Shell every month. The monitoring service has already identified several problems, including a cracked cylinder head and it has enabled Denby to extend its drain periods from 3-4 weeks to 5-6 weeks.
