*Elroi, Jmtyre; Sirs huwag nyo lang po madaliin ang start and stop ng monty nyo, suggestion lang po basi sa na experience ko sa power plant. 1. at cold start since wala tayong basihan ng lube oil temperature, 5 minutes warm up enough to reach lube oil temp to 45 degC and enough to recirculate the lubricating oil on the turbo charger bearings. 2. kong na pa andar na puede na sa 2-3mins. 3. during stopping, cooling down, 5 mins o sobra pa; this is to protect the turbocharger from possible lubricating oil starvation. at a sudden stopped lubricating o oil pump also will stop and will result to minimal o stoppage of oil supply to the turbocharger bearings, during this time eventhough no combustion on the engine the turbocharger is still rotating caused by the heat from the uncooled engine. sana makatulong to.
