VR 1 racing, it has anti-form addivtives for high rpm use. Not sure how much zinc is still in it-used to be alot, but that comps stuff-12oz bottle-should make sure its good.
I think you are worrying too much-first it was what cam to get, now its what oil. Get out and enjoy that car. You know how to change a cam youself in the car so if it does wear out--and they all wear out--you can just change it agian. It should last, even with the cheapest oil 1 year, maybe longer. Yes it alot work but then again not really. Its not like a new car, were you have to pull the motor out and spend thousands of dollars to change the cam.
Heck you should be more worry about your own health, does not sound like you are in your 20's or 30's. I am in my 40's now and it stinks. My back gave out last night and I was just bending for a while-no lifting. Feel better today but whats going to happen to me say another 10 years. Might just have to buy a new Buick and forget about all this.
