Thats what I was thinking about trying, right now I use Castrol GTX high mileage which is a syn blend, no leaks or oil useage issues, not sure about going full syn with 255k miles

Meh, do it. I have 310k+ your engine will thank you.

The Chevy dealer sells acdelco oil filters for $5 out the door, you can't beat that.

I buy M1 high mileage 5w30 at Walmart for $23 I believe.

Lol ya, thats why im leaning towards it but don't wanna get some massive leak I mean on the blend its fine so full syn should be ok, and yup thats what I do run the AC Delco filter, alotta people say its not that great but could never really get a 100% positive on a filter to use lol

Don't. You've got some researching to do if you think adding any additives to engine oil could be beneficial.
