So this is our 2018 F250 6.2L at work that I'm driving this week. Doesn't leave the plant site really, gets up to 80km/h couple times a day going from the plant to camp. Basically -20 or colder days of winter and hot days of summer it pretty much just idles all day long, heat or AC. Still starts and runs like new, doesn't burn any oil. Has lived it's life on a diet of whatever semi synthetic the mechanic was buying in bulk getting changed when the OLM says so. Works out to 492 days worth of 12 hour shifts of idle time lol
