Oil change interval
Just wondering, what is the month range oil change interval on these trucks? I know it's 5,000 miles but I didn't know how many months. I changed mine like last march and haven't even put 2,000 miles on it since then...wondering if I should change it again?

In my opinion not driving very often or very short trips falls under severe conditions.
3000 miles.
My reason for saying this is condensation inside the engine.
Short trips does not get the engine up to operating temp long enough to cook the water out of the oil.
The water combines with sulfur compounds to form sulphuric acid in the oil pan.
How ferrous metal and acids react is not good inside an engine.

that is considered severe duty like dave stated and every 6 months at least
a lot depends on location , humidity etc. and how much condensation occurs in the engine as to whether it needs to be done more often or not
