My husband changes the oil in the all the cars as well as the filters. I love that he knows how to do that. It saves so much money and it is a big relief because I don't trust most mechanics.
We hire a mobile mechanic that we like a lot to change the breaks and do other stuff that is too hard for us to do on our own. He always does a great job, he is a lot less expensive, has years of experience, and doesn't always suggest that I need this or than done to my car.
