SLOB vs STP oil treatment

[Doc8404]

While at Walmart, i noticed that STP oil treatment (small 15 oz bottle) has ZDDP....

which would be better, that or slob?
is this recommended every OCI or every other since i've heard it can burn up the cat?
this is for my 92 Galant.

I spend a few dollars more for VSOT.

i hear it's better stuff, but i got this stuff on sale and now wondering how to use it LOL

VSOT should have much better VIIs than STP I would guess. I would not get STP, way too thick, I think 2 or more times thicker than VSOT.

If you find a product with low quality, on sale, do you buy it just because it is on sale?
Isn't it supposed to do something, besides being cheap?

My "book" says not to add anything to the motor oil. I wonder why?
