Its not designed for "damaged engines" nothing out of a can can fix that, and Restore does not claim that at all.
Its is for worn engines. A 250K mile engine may very well be "mechanically sound" but worn. For example my roof is 15 years old, but no leaks at all. It is "mechanically sound" but is worn. Not hard to understand this.
If its temporary, then why wouldn't it be added at each change? Thats exactly the instructions it gives. Can you explain how a product that "increase compression" (your own words) is NOT beneficial?
