Very platform specific, as noted above they all do things a bit differently.
And despite all the hoopla the pics above are not impressing me at all. The second pic shows a valve that I certainly would call fouled in any engine I tore down...
It was one 20min run after 40k miles. Imagine what doing that every 5k miles or even 10k miles could do.
Indeed. Makes sense that a harder driver would probably have less carbon build up/valve deposits. Been that way since I started driving over 40 years ago.
Really appreciate the info, as we all pretty much have a DI car or truck in our future...
