15w-40 dino oil isn't ideal but it didn't cause your problem, IMHO.

I'm still stuck on the emissions system. And maybe on it causing the turbo to commit suicide.. And I still maintain that I could be spectacularly wrong.

This is interesting to me, and should be to the rest of the Board, because those who already own, and those who might soon own, one of these tractors should know if we have to take any special care when running one in extreme cold.

I agree dino is not the best, but especially in the cold with a turbo. At least the dealer could have used Rotella T6 5W40 which is fully synthetic.
Not to pick on anyone, but turbos are a beast on their own, one cannot treat a turbo engine the same way as non turbo especially during warm-up and cool-down.

Well, seems I'm in the same boat. XR4155HC, 8 months/32hours old. Did some loader work moving snow, then headed back to the house. Dropped the rear blade on the way back to the house. About to he garage when the motor started spewing smoke, puking oil out of the exhaust pipe, tried to throttle down but engine would not cooperate. Dealer briought me a loaner today and took mine in for repair. Preliminary diagnosis was turbo let go. Waiting for report on damage.
Well that stinks. I think you and Rusty are certainly sharing the same boat.

I'm wondering if LS got a bad lot from the supplier or something else. We probably won't know what the exact failure point is on the turbo unless the dealer takes it apart.

0F isn't extremely cold, at least for the midwest here. I run T6 and have operated it at -25F blowing snow during the last cold snap, but I wouldn't consider starting it without the plug heater. Lot's of warm up time.

Some good theories discussed and sounds like something that could possibly be dealt with with a software upgrade?

I don't get it. They know intake air temp, DPF temp, fuel temp, coolant temp (don't see an oil temp sensor). Seems like they can infer the conditions of operation if it has to do with extreme cold and not letting it regen.

Just out of curiosity, does anyone follow LS on their FaceBook page? Any discussion on this issue?

I'm not on FB, thus the reason for asking.
