X15 questions

[Rawze]

Seems a bit high to me but I am only speculating here ... Older model engines, unusually high oil temps would be a sign of something wrong in the combustion chamber (bad delete or other issue like incorrect program, a bad sensor that is throwing things off, slipped cam, etc.), something causing excess friction, or the turbo overheating for some various reason (leak in CAC, clogged intake filter or clogged exhaust, over-spooling, etc.). A bad/leaky oil thermostat or higher than normal coolant temps can do it too.

Not sure about the X15, but the CM2350, 2250, 871,870, etc... it is considered high if it gets into the 230+F range unless the engine is just being lugged at 100% throttle up some big mountain somewhere under heavy loads. It is considered excessive if it is in the 240+F or higher range.

That is just my opinion though ... some claim the oil temps run higher for the X15 in general, though I am still somewhat skeptical.
