"I am sure the car will run at -35, and if you only started it once at that temperature, things would be fine. However the collective wisdom is that the M96, from the factory, doesn't like cold starts, and eventually will chew itself up."

This is exactly the type of BS that keeps these threads going...

Go Celsius!

+34 down here today can't imagine - 40 that's definitely not for me

Yeah, it's not for everyone. I don't go out at -40.

-30 is the cut off for me. Anything colder than that, it doesn't matter if you have heated handle bars and visor, you're gonna freeze.

I think it more or less is the warm up cycle that does the bore scoring. Your can drive in winter but only coming from a warm garage and back without letting the engine to cool down in freezing temps.

Zookie, your 3rd engine? I thought you only had it rebuilt once?

Had my 02 996 Carrera for three years. Parked outside in all kinds of weather in Norway. Two of the winters were quite nippy, lots of snow and ice. No issues, started as normal every time, just loads of fun. It even climbs steep hills when snow and ice. Probably because of all the weight over the back wheels. Typical problem one might have to resolve during a cold winter is the battery, as a degraded battery really shows how degraded it is when cold. Resulting in the starter engine not kicking in. Oh one more thing, the common problem with majo gunk in the oil filler tube is more prevelant in colder climate as oil fumes cool down and condenses in the top part of the tube where it is horizontal.

Although the engine was poorly rebuilt according to the new rebuilder, workmanship was not the reason for failure
It was the B-Grade IMS Bearing they used from Pelican Parts which they failed to mention otherwise I would have changed it earlier.

I started and drove my car recently when it was -10F outside.

I don’t just keep revs under 3,000, I also keep throttle under 15% or so. Even opening the throttle halfway can cause the cylinders to fill completely with fuel/air, generating close to maximum available torque at low RPM, which can still generate a lot of heat on a cold engine.

I also run 0w-40 oil. The oil choice is important at really cold temps.

Ha, -14F this morning here in Minneapolis while I was driving my 996. My biggest challenge in the cold weather is the non-stop fogging up of the windows...

Took mine out today in Southern Illinois, with ice, snow, and the tropical temp of 8F. Had to get my new headlights.
Like everyone else said, let it warm up, and with the all season Yokohamas, it got me everywhere. I also run 0-40w oil.
