I change mine with excellent reports every 15k. I KNOW the condition of my oil and engine, very few do.
Easy to keep track of.
I saw on my 5.7L gas engine, a bit of a jump when I ran to 15k. That time I also used std mobile 1 instead of extended life.
My wife's garage queen, it get changed at 5k... only because I don't like oil sitting in an engine for more than 2 years.
