I have a 12 year old GMC 6 liter pickup with about 55000 miles on it. I put 1300 miles on it in the past 13 months since the last oil change. It has had a blend of dino and synthetic oil in it chained regularly since new. The dash board registers at about 65% oil life remaining.
Do I take it in or let it go for a few months? And if so, how many?
