UOA 5w20 PP. 2014 T&C 3.6l. 90k engine. 7400 oil

[Firecat40]

First post. I found sandy oil in my intake plenum changing spark plugs. Immediately changed oil and took sample mid drain stream with Wix Napa kit. I expected the report to show high wear and silica... Also using k&n air filter. I believe the dealer failed to seat the rubber intake tube to the throttle body when replacing leaky oil cooler a year ago. Van has had nothing but 5w20 Pennz Plat since free first change at 2k. Filters have been wix/napa 10010 or fram tg or xg or mopar.

This van tows a 3000 lb. boat a few times a year at 2500 rpms sustained for 240 miles or so and frequent short trips. Has been super reliable other than ac and power sliding doors.
