Okay, I recently inherited a the vehicle described above. I won't go into all the details, but it was actually driven nearly daily by an elderly family member who bought and shortly after found out he was very sick and never got to use it for his intended purpose. It has the 3.7 gas engine. Anyway I'm wondering if there should be some special considerations regarding which oil I use. I've always been a huge fan of Mobil 1. However, I have a bum hand so I had to have a shop do my oil change and didn't even think of telling them which viscosity oil I wanted them to use. Considering that it was only driven on short trips until I got it do you all have any recommendations. For engine oil. Its also 4wd so I want to have all the drive train lubricants and break fluid changed too.
