My wifes truck uses 8 1/2 quarts of Magnatec 5w-30. I use those leftover 1 1/2 quarts and mix with a jug of 10w-30 GTX and use in the Jeep (I use the REALLY large filter, Wix 51773). Since I currently live in North Chicago, I figure that little bit of synthetic will help come winter time. When I get back down to D/FW next year, it will get the same Magnatec that the wifes truck gets.
Edit: changes come at 5K and with a Wix filter.
