I have an 87 300 SDL, I'm thinking that I want to start doing my own oil change rather then taking it to the dealer who decided they are going to start charging me $60 or taking to any other shop that I don't trust to do the job correctly (makes me sound a little over protective of my car, but I've just had bad luck with garages ). Anyways, I was wondering if anyone out there can give me some advice on how difficult it is to do the job and does it require me to deal with the belly pan in any way. I check the board and no one has posted anything about this in the past. If the job is easy enough I'm thinking it will be as easy as it is for me to work on my families other cars (Honda Civic and Nissan Altima), correct me if I'm wrong.
