Tldr: The title lol.

I have a 99 Chevy s10 2.2, and it has been running synthetic blend oils (5w-30). It is at 112k miles. And since I am doing my own oil changes, I noticed that blends and full are damn near the same price.

I have been doing 5k intervals with blend, should I go to a 7.5k interval with a full? My truck has a highway maintance schedule in the manual that says it could do 7.5k going by highway miles. I drive mostly highway (speed limit near me goes to 45 at the lowest).

    You could, but why? You have an almost 25 year old truck. The 5k intervals have halped it last this long. How much can you really be saving by going 50% longer?

      Well putting in a nicer oil I would assume id get more performance out of it. Im doing 90% highway 10% city and the manual says 7500 mile intervals doing highway is just fine. And it was designed when oils were worse than they are now. And its only got 112k miles.
