Oil pressure drop
Once the engine warms up, the oil pressure drops enough to trigger the check engine light every time it dips below the threshold. I decided to try an aftermarket oil filter, but it looks like I’ll be switching back to the pricey OEM one after all.

Perfect OEM replacement
An amazing alternative to the expensive OEM filter. Works just as well if not better.

Parts that fit!
It’s hard to find ‘official Mopar’ parts for the 3.0 Eco Diesel but Doc’s Diesel are exact matches and are as good or better quality as factory.
