I used restore on an older engine, no difference.
I don't really believe in a miracle in a can with exception to seafoam, use it once a year or so.
I have 130,000+ on our Yukon and it runs great, change plugs, wires, seafoam, chevron tech....stuff once in a while and I change my tranny fluid once a year (pan dump and new filter). Original tranny and no problems. I also flushed radiator, new power steering fluid, flushed new brake fluid in it and cleaned the front wheel sensors after packing the bearings with grease (yep, took the cover off that says not to!
)
I think restore is intended to fill pits in the cylinder walls to give better compression.
I run Mobil 1 oil since about 72,000 miles and haven't turned back (Napa Gold/Wix filters) change every 5,000 miles, easy to remember
