(The AC was on i'm not sure if that had anything to do with it because of the extra load on the engine maybe). But anyway..the big question is should i be getting some kind of oil additive? Or are those frowned upon. I'm not sure if its a rumor but i heard if you use "Restore Engine Additive" you need to KEEP using it?

I used engine restore twice on an engine like yours and it did not in any way reduce oil consumption....
the use of 10-40wt is not the correct oil for our engines,,GM advised that this oil must not be used....10-30wt oil is the correct oil...if you wish to try a heavier oil use 30wt in the hot weather then 10-30wt when cooler temps return...synthetic will reduce your oil problems and crankcase contaimination,,but it will cost twice as much for the product..and the reduction will be slight...
as you know , my opinon is , your engine needs lots of work..
no additive will correct this.
