3.0L EcoDiesel

Doc's Diesel 3.0L EcoDiesel Parts

One Engine Family. Every Platform Covered.

The 3.0L EcoDiesel got around—RAM 1500s, Jeep Grand Cherokees, Wranglers, and Gladiators all carried the torquey V6 that made diesel practical in the light-duty world. That spread is great for owners and confusing for parts shopping, because the EcoDiesel badge covers multiple generations that don't share components. This collection is Doc's complete EcoDiesel coverage: every platform, every generation, sorted so the parts you order are the parts that fit.

Every EcoDiesel, One Collection.

Oil filters and fuel filters built for the 3.0L's tight tolerances, engine air and cabin air filters, complete filter kits, oil change kits with the correct 10.6-quart capacity, and diesel treatments for cetane, injector health, and winter protection. Whether yours wears a RAM badge or a Jeep badge, the maintenance program is covered.

Built to OEM Specs. Backed by the Doc's Fitment Guarantee.

Every part meets or exceeds OEM design, fit, and function, keeps your warranty intact when installed correctly, and is backed by the Fitment Guarantee: doesn't fit, we make it right. No guesswork. No BS.

Doc's Makes It Easy.

This is the engine family where the Vehicle Selection Tool earns its name—generations differ between the 2014-2019 and 2020+ trucks, and Jeep and RAM applications aren't interchangeable. Enter your exact year and model, and shop only what matches.
