Yes! x1000- this stuff is not snake oil. I actually fixed a rear main seal leak with auto-rx once. I have run it through my LT5 as well since I had a half a bottle left over from another project and used it as sort of a preventative on the lifters.

It also tends to unstick carboned up ring packs which helps a little with emissions.
