I though that was more for race cars!!! Where do you live Mike? I thought Texas was the hot hell hole here:p
I don't think I'll go above 90W unless someone has really good reasons for it? It does get a litlle cold here starting next month for 2-3 months especially at night and then back to the frying pan for the remainder of the year.
I was just wondering if Mobil 1 75W-90 is better than regular oil with 75W-90 or 80W-90.
