This being a light truck engine though, it might be on the fragile side, so an early OCI is probably best.
I used to subscribe to changing at 1500-3000 miles, but the last few new vehicles I've had I have followed the manufacture's recommendation which, in most cases, has been 5k. In my experience so far, the engines seem to run better based on mpg, etc if I do that. It is hard to resist the early change though because my grandfather and dad were mechanics and that's what I did before in the 80's and 90's. But now, with all the advancements in metallurgy, engine design, filters and oil, I think it is best just to follow the recommendations. It has been just fine in my experience anyway, and probably even beneficial.
