 Subject: Piston Coating in my Oil??
IP: Logged
Message:
Hello,
I am a Durango 4.7L owner, but have come here before to lurk for good advice. When I changed my oil today (every 3.5K miles with Mobil 1 and PureOne filter) I noticed what looked like paint flakes in the oil I drained out. (Truck has 21500 miles). I took samples to two different dealers and each said it looked like some of the anti-scuff coating from the pistons. They see this often and it is nothing to be concerned about. I can't help but be concerned about 1/2 teaspoon of "paint flakes" in my oil possibly clogging ports, etc. Appreciated any thoughts or other experiences with anything similar
TIA

I got my 98 with 65,000 on it. It has that 5.2 auto and I noticed that since I changed my oil the first time that it takes a couple of seconds to get oil pressure. This concerns me deeply. This morning I heard soem noises when I started it up. I used Pennzoil with Pennzoil filter first, then Pennzoil synthetic with a Bosch filter, now I am on Mobil One with a Mobil filter. It now has 78,000 on it.
I don't see any flakes though. If I do, I will FREAK OUT!

Tip: DO NOT use Pennzoil. I never understood why until we swapped out the engine in my parent's '90 Jeep Cherokee and a friend pointed out the sludge that it deposits because they use parafin wax in the oil.

It is far better that the coating take the abuse instead of scuffing the skirt. I do not know how normal it is. I have nly seen this coating on HP imports and race engines. I am sure that over time it has to wear off. It is there to prevent reduce piston scuffing. I have no idea how long it should last.
