In regards to oil changes, I go to a Jeep dealer in Flagstaff since there is NO Chrysler dealer anymore. Interesting they also do my midterm service on my other Mercedes. The Jeep dealer at one time stocked 0-40 Mobil 1 because one of their Jeep cars specified it. Probably one of the Daimiler-Chrysler models. Well they will special order it in for me if I give them notice and I bring my filter. Last time there was NOT a drop of Mobil 0-40 in Flagstaff and they ordered it from Phoenix. Also only Napa carries the filter for the cars (XFs and Merc) and they only carry one in stock. Air and cabin filters are also special order. Keep a supply of all consumables in my garage. So if the other three Xfires in town or the four other Mercedes get there first you have to order one in. By the way, the same is true for the wipers on the Mercedes. They only stock one set in town. It is a town of 60,000 but hardly anybody has Mercedes parts in stock. We have one German Independent and the Jeep dealer has the only Xfire mechanic. Went there after Chrysler dealership closed. Mercedes dealership I go to in Phoenix only uses Mobil 1 0-40 in the cars that say to use it in the owners manual. They do not subsitute 5-30 in 0-40 cars. Maybe when it is gone they will change their tune.

I can only buy Mobil 1 0-40 in quarts.
