I found a new little thing from Chrysler. Where you can get 28 diesel oil changes for $20 each. You have to use them within 84 months from the time you buy them and are not transferable. You can but as many miles on as you want. No milage rules. I can do them for Dodge Chev and ferd! These are service contracts from Chrysler. They can be used at any Dodge Chrysler jeep dealer. email me if you want more info.
