I've quoted the whole 'conversation' for context, and highlighted the very important facts that you chose to ignore. You have a habit of doing that. Why you like to prove publicly that you're an ass has always been hard to understand, but it is a source of amusement, so it's appreciated.
So, to pr?cis, I believe my car would develop no problems whatsoever running 0w15 based on the exhaustive tests that have been done AND THE WAY I USE MY CAR. I would not use 0w15 if I was doing Targa Tassie or Le Mans.
