I have found this at a Auto Zone in my area and am using this now. My question is other area stores do not have the German version, is there any other way to get this if they stop carring it? I changed out the Mobil 1 0-30 yesterday when there was a heat wave (22F), its now almost -11F. Many on this site have high reguards for this oil but how many are actually using it? Thanks Guys p.s. This is in my 5.3 Chevy.
