You might even say they were "active" cleaning agents.


Nah,their secret agents!!

We have a 2003 Pontiac Montana we have owned since new. It's at 87,000 miles now.

At 1500 miles, I changed the oil to Mobil 1 and a new AC filter. Since then, the oil and filter have been changed when the Oil Life Monitor indicates (varies between 6500 and 7300 miles) using AC filters. Mobil 1 was used until last Spring when Wal-Mart had none on the shelf so I swtiched to Pennzoil Platinum.

Looking through the oil filler, the rockers/springs/etc. always looked very clean. The used oil was always darker than new, but still looked good (very subject, I know).

But the first fill of PP became much darker than usual by the time I drained it. Not black, just darker amber/brown. The two subsequent drains have not been so dark and the rockers/springs/etc. look even cleaner - it honestly looks like new!

Based on my observation, there is a small buildup of dirt/varnish/whatever even with Mobil 1 since new. And Pennzoil Platinum cleans out what Mobil 1 left behind.

I noticed the same thing in my SVT Contour. It had M1 since birth but one run of maxlife noticeably changed the slight varnish color I could see through the oil filler. Of course the Maxlife will probably turn it another varnish color.

careful not to washout all the sludge you wont want any leaks

Thats exactly (and I mean exactly!) my experience, too. I used M1 exclusively in a 2006 Honda Odyssey, and with each subsequent PP change, the oil goes from very dark, to lighter, to almost "new".

I am not saying M1 is a bad oil at all. Im just verifying what Ron posted, exactly.

If there were a Pennzoil Platinum high mileage formula, I would never need to buy any other oil again.
