There has been a lot of talk about Group 4 Synthetics being able to clean engines extremely well. Then there have also been discussions about MaxLife and many High Mileage oils to have a lot of cleaning agents in them. My question is specifically about Pennzoil Platinum, a highly regarded oil on here. I know it's a Group 3 oil and wanted to see if it has a strong additive package for cleaning engines and keeping them clean. This oil is used in my home in the 5W-20 (used in a '06 Honda Pilot) and 5w-30 (used in a '04 Infiniti G35 & '99 Nissan Maxima w/ 125k miles on the odometer and two cleaning and rinse phases about 5k miles ago with Auto-RX).
Wanted to see some feedback regarding the cleaning agents in this oil from the experts on here.
Thanks
