Oil Change Kits

Doc's Diesel Oil Change Kits

Skip the Waiting Room, Not the Quality.

There are two ways to get a diesel oil change. One involves a dealership waiting room, a service writer upselling you a cabin filter, and a bill that stings worse every visit. The other is thirty minutes in your own driveway with everything you need already in one box. Doc's Diesel Oil Change Kits are built for the second kind of owner—each kit pairs premium full synthetic diesel oil with a new Doc's oil filter, matched to your exact truck, so the job is done right, done on your schedule, and done for a fraction of the shop invoice. You know what went in your engine, you know it was done right, and you were back on the road before the dealership would've gotten you into a bay.

One Box. One Afternoon. Done.

Every Oil Change Kit includes the oil your engine calls for and a Doc's oil filter built to protect it—high-flow synthetic media rated at 25 microns and 99% efficiency, a heavy-duty metal housing, and an anti-drain back valve to guard against dry-start wear. No cross-referencing filter part numbers, no standing in the oil aisle counting gallon jugs against a capacity chart. The kit matched to your truck arrives with the right spec and the right amount, whether you're servicing a Cummins, Powerstroke, Duramax, or EcoDiesel. If you know your way around a wrench, this is the oil change with the hassle already removed.

Dealership Quality. Zero Dealership Required.

Skipping the dealership doesn't mean skipping the standard. Every component in these kits is engineered to meet or exceed OEM design, fit, and function—and installing Doc's parts correctly keeps your factory warranty fully intact, no matter what the service desk implies. The oil is formulated for severe diesel duty: wear protection under load, oxidation resistance at temperature, and dependable cold starts. And it's all backed by our Fitment Guarantee—if anything in your kit doesn't fit your truck, we'll make it right. No guesswork. No BS.

Doc's Makes DIY Oil Changes Simple.

Find your kit with our Vehicle Selection Tool—enter your year, make, and model, and we'll pull up the exact kit with the correct oil spec and quantity for your engine. Then stay on rhythm: change your oil every 5,000 to 7,500 miles at most, and lean toward 5,000 if you tow, haul, or work your truck hard. Pro move: order your next kit when you finish this service. A kit on the shelf means the next oil change happens when the interval says so—not when you finally find time to shop for parts.

Free Shipping on All U.S. Orders $99+

Do the math on a year of dealership oil changes and these kits pay for themselves fast—especially since most kits clear our $99 free shipping line on their own. Add a bottle of oil friction treatment or a set of wiper blades and the whole order ships free anywhere in the U.S. Your truck. Your driveway. Your oil change—done right, every time.
