[QUOTE="realjones88, post: 1296006, member: 26560"] Ecoboost turbos are cooled by the both the coolant and engine oil. When you turn the engine off fresh coolant is continuously moved through the system by convection until lower temps are reached. Basically truck off = turbos still being cooled. The old turbos you are thinking off (like from older cars or some diesels) were cooled by engine oil ONLY and so yes with those you did need to leave the engine on for a bit to cool them down. Zero need for an extended idle time before turning the truck off. I would disable start/stop though dumb feature imo. [/QUOTE]
