City buses face a heavy task: on call 24 hours a day, 7 days a week, changing drivers, tight timetables and fulfilling high expectations in reliability. Despite increased maintenance intervals, they have to keep running while still complying with stringent emission requirements. Daily maintenance – in particular checking and topping up engine oil – plays a key role in keeping the engine in condition. The differences in service requirements of multi branded fleets even increases the complexity of the daily maintenance routine. However, when done manually, it takes time and buses cue up waiting for their daily check. Groeneveld offers the solution with the Oilmaster, a product as successful as the well-known Groeneveld automatic greasing systems.
