I've been reading several threads and posts about problems people have had with some dealers and service stations, even for something as simple as an oil change. There are stories of these places telling you to come in every three months, trying to hard sell you things that are not related to the oil change, not doing a good job, stripping oil pan threads, etc., etc. Even people that bring in their own oil to these shops wonder if they are really getting it. I use to change my own oil, then had it done for a few years, and now that I have a new truck I have decided to once again do it myself. I installed a Fumoto valve and the changes should be a snap (I have not changed oil since I bought the Fumoto but it looks easy enough). Now, if I could find an oil change place or mechanic I could really, really trust, things might be different. But physical/handicap problems aside, why do you pay others to do an oil change?
