摘要：	Extended oil drain intervals are only appropriate for certain types of duty cycle. Recognising this to be the case, truck builders have devised matrices to help them determine when they might be acceptable, says Adrian Hill, technology manager at Morris Lubricants. Suitability tends to involve long-haul work, he says. "Cruising down a motorway is a lot easier on both the engine and the oil than local stop-start work," he points out. Regular multi-drop runs around big cities mean that the lubricant endures a heavier soot loading and may be diluted by unburnt fuel, causing it to lose viscosity and reducing its effective working life. If a truck tackles regular runs from one end of the UK to the other, however, then 150,000km drain intervals using an oil whose specifications show that it can cope with them are perfectly feasible; and without components suffering any ill-effects or the engine's life being shortened. "Some manufacturers are looking at 200,000km," he adds.
