The pictures are from my wife's Murano. If you want to stop reading, that's okay. I just didn't want to go disassembling my Bronco when I could practice on my wife's SUV.
Anyway, the pictures are with 26,000 miles and the car is about 14 months old. I took the first two photos 1,000 miles ago. Yes, I switched to Amsoil oil but also was interested in their PI engine cleaner ability. So I removed the spark plug, before using the PI cleaner, @ 26,000. Just over 27,000 I removed the spark plug again, I see a noticeable difference.
Carbon build up is something to consider. I just couldn't believe that her car already had that much build up on it in one year. I was also pleased that one PI treatment helped.
This post is about the PI cleaner and showing proof it works. There is more that could be discussed but I will be putting this in my other vehicles now every oil change.
Photo 1 - BEFORE: can't see the complete outer rim of the piston.
Photo 5 - BEFORE: you can see a close up of buildup...also noticed on left side of small piston ring
Photo 10 & 19 - AFTER: you can see both piston rings and the buildup area (more noticeable in photo 5) is greatly diminished...even starting to see a little shine come back.
