From what I've read on these forums (and if I haven't mixed it up), the actual combustion process itself is very close to something like 95% or 99% efficient. Anything that improves on that, even bumping it up to 100% efficient, still won't be noticeable by the time it goes through the drivetrain and wheels. It MAY barely help (performance and/or emissions) in an old engine in desperate need of a tune-up, but a newer engine won't show anything.
