It can't repair damage to a block due to the siezed rings carving away at the cylinder. Have you performed a compression test or scoped the cylinder to signs of wear? If you've gone for too long with high oil consumption, there's a chance the damage is irreversible.Thanks for sharing that with us.
I have run Valvoline Restore and Protect for about 32,000 KMS ( 20,000 miles ) on two oil changes but, so far, haven't noticed any difference in consumption.
Two more oil changes to go.
