Anyone using Mobil 1 at the 0W-XX weight? I'm curious. I've been using a synthetic blend 10W40 in my 300SL, but my MB independent service garage has recommended and is using only Mobil 1 "0W" now. It is manufactuer approved for use in all Daimler / Chrysler vehicles. Geez, it's thin as water at room temperature. But even if it costs twice as much, if I only need to change it 1/3 as often, it's a saving in "hassle" time. What do you think?
