2020 Ram 2500 6.7 Cummins Oil Type

So, there I was, under the hood of my buddy's truck, trying to figure out why his 2020 Ram 2500 was making a noise like a metal band's warm-up. I'm no mechanic, but I've watched enough YouTube videos to be dangerous. As I was wiping my greasy hands on my jeans, I thought, "You know what this truck needs? A good oil change."

Now, you might be thinking, "Dude, that's obvious. What's the big deal?" Well, friend, let me tell you, not all oils are created equal, especially when it comes to the beast that is the 6.7L Cummins engine in the 2020 Ram 2500.

Meet the 6.7L Cummins: A Diesel Legend

Before we dive into the oil type, let's give some respect where it's due. The 6.7L Cummins engine is a diesel legend. It's been around since 2007, and it's known for its torque, reliability, and that distinct diesel rumble. It's like the grandpa of modern diesel engines, wise and full of stories.

But even legends need a little TLC, like regular oil changes. And that's where the fun begins.

What Kind of Oil Does the 6.7L Cummins Like?

Alright, so you've got your oil filter, your oil, and your wrench. You're ready to roll. But wait! What kind of oil should you use?

First things first, the 6.7L Cummins prefers full synthetic oil. It's like the caviar of oils, but it's worth it. Full synthetic oil has better viscosity control, which means it stays thicker for longer, providing better protection for your engine.

Now, let's talk about viscosity. You'll want to use 15W-40 oil for your 2020 Ram 2500 with the 6.7L Cummins. This viscosity rating means the oil is thin enough to flow easily in cold temperatures (15W) and thick enough to provide good protection at high temperatures (40). It's like the Goldilocks of oils, just right.

What About the Oil Filter?

You can't talk about oil without talking about filters. The 6.7L Cummins uses a full flow oil filter. This means it filters all the oil that flows through the engine. It's like having a bouncer at a club, making sure only the good stuff gets in.

As for the brand, you've got options. Some people swear by Fleetguard, while others prefer Mopar. The important thing is to get an OEM (Original Equipment Manufacturer) approved filter. It's like inviting the right people to your party. They'll make sure everything runs smoothly.
