One of my colleagues has just bought a 3.4V6 Colorado (VZJ95). It has 80k miles but the last oil change was at just over 50k, around 18 months.

First thing he is going to do is change the oil, but he was wondering whether he should do any "extras" such as use a flush etc. Now I've heard pros and cons of using flushes etc. :?

As I wasn't sure, I thought I'd ask here....... Thanks in advance. :thumbup:
