Hi there Scotty, I just watched your video regarding your advice and it feels like a very tricky situation I am in. I don’t know if the oil has ever been changed but I believe when I first bought it that I saw on the report that it was maintained the fluid was red and just has recently anywhere from a half a year or so it could have started turning dark brown. I have a 152,000 miles on it and I was just told by another mechanic that if it’s under 200,000 then it’s still ok to change it. He also quoted me 350$ which is a pretty hefty price.  From what I have described do I possibly have a problem? It has been humming since I got it. I just haven’t had much to put into it during these times.
