Hi folks. So we got you looking up chutter in the thesaurus, eh? I've often used chutter to describe cold induced shudders. ch for chilly I guess...

I now use the lower weight oil in the winter. My dealer never got it in until 3/4 of the way through last winter. I wasn't impressed with them. My car still has the ocassional shudder immediately when starting up, but I believe less often and less shaking. I'm not sure if this improvement is since I'm using the 0w20 oil in the winter though. I wasn't impressed with the dealer. They're asking me why I want that oil when it's clearly recommended for the car in my climate. (Ottawa, Canada where we can hit -30 C for short spells.) I'm not convinced what exactly causes these start up shudders. I'm almost thinking it's not sluggish, viscous oil due to the inconsistency of it occuring. ie. It doesn't happen all the time and I've had stronger shudders on relatively warmer mornings. I've mentioned all of this to my dealer. - no response.
