Doc's Diesel Jeep EcoDiesel Parts

Maintenance Built for Diesel-Powered Adventure.

A diesel Jeep is a different animal. The 3.0L EcoDiesel V6 turns a Wrangler, Gladiator, or Grand Cherokee into something the gas versions can't match—low-end torque for crawling, real towing capability, and the kind of fuel range that makes remote trails and long hauls actually practical. But that engine only stays that way if you take care of it, and EcoDiesels are famously picky about clean oil and clean fuel. That's where Doc's comes in. This collection is every EcoDiesel maintenance part we build for Jeep—filters, kits, oil, and treatments matched to your exact model year—so you can service it yourself, skip the dealership bill, and keep that diesel doing what you bought it for.

Everything Your EcoDiesel Needs, In One Place.

We cover both generations of diesel Jeeps: the 2014-2019 Grand Cherokee 3.0L EcoDiesel and the 2020-2025 Wrangler and Gladiator 3.0L EcoDiesel. Inside this collection you'll find oil filters and fuel filters built for the 3.0L's tight tolerances, engine air and cabin air filters, complete filter kits that bundle a full service into one box, and oil change kits that pair the right filter with the right full synthetic oil at the correct capacity. Add in Doc's diesel treatments—cetane boost, injector cleaning, cold-weather protection—and you've got a complete maintenance program for an engine that rewards owners who stay on top of it.

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

The EcoDiesel doesn't tolerate sloppy parts, and neither do we. Every filter and kit in this collection is engineered to meet or exceed OEM design, fit, and function—no adapters, no modifications, no wondering if the seal will hold. Modern common-rail diesels like the 3.0L live and die by filtration quality, which is exactly why Doc's builds to the spec instead of down to a price. And with our Fitment Guarantee, if a part doesn't fit your Jeep, we'll make it right. No guesswork. No BS.

Doc's Makes It Easy to Service Your Jeep.

The fastest way to the right parts is our Vehicle Selection Tool—enter your year and model, and we'll show you exactly what fits your EcoDiesel, whether that's a single fuel filter or a complete maintenance kit. One heads-up for diesel Jeep owners: the 2014-2019 Grand Cherokee and the 2020-2025 Wrangler/Gladiator run different generations of the 3.0L, and their filters are not interchangeable—so always shop by your specific year rather than grabbing anything labeled "EcoDiesel."

Grab a full filter kit or oil change kit and knock out the whole service in one order—every order over $99 ships free anywhere in the U.S. Your EcoDiesel takes you off the beaten path.
