If you have an idea of where you will be when you think you'll want the oil changed, post up on here and see if any members live in that area and can recommend a shop. When my transmission died in Murray KY, I found forum member Gale Hawkins who lives in Murray KY and he was able to recommend a good repair shop that was also a Jasper dealer. The forum has grown so much that the probability is high that you will find a member that can recommend a shop closer to where you will be.
I agree about the quickie oil change places, plus they don't lube the front end which is a problem for me.
