2018 Nissan Pathfinder Oil Type and Capacity Explained

Knowing the exact 2018 nissan pathfinder oil type and capacity is the first step toward keeping your SUV running smoothly for the long haul. If you're like most owners, you probably just want to get the job done right without a lot of guesswork or trips back to the auto parts store because you bought the wrong weight or not enough bottles.

Let's break down the specifics so you can tackle your next oil change with confidence.

The Short Answer: What You Need to Buy

For the 2018 Nissan Pathfinder, which comes equipped with the 3.5-liter V6 engine (the VQ35DD, for those who like the technical codes), you are looking at a very specific set of requirements.

The Oil Type: Nissan recommends using SAE 0W-20 engine oil. The Oil Capacity: You'll need 5.1 quarts (or about 4.8 liters) if you are also changing the oil filter, which you definitely should be doing every single time.

If you happen to be doing a "dry fill"—meaning the engine was just rebuilt and has no oil in it at all—the capacity is a bit higher, around 5.7 quarts. But for a standard maintenance oil change, 5.1 quarts is your magic number.

Why 0W-20 is the Right Choice

You might notice that older SUVs used thicker oils like 10W-30 or 5W-30, but the 2018 Pathfinder is designed for the thinner 0W-20. There's a good reason for this. Modern engines have much tighter tolerances between their moving parts.

The "0W" part of the rating means the oil stays thin even when it's freezing outside. This allows the oil to circulate almost instantly when you turn the key on a cold morning, protecting your engine during those first few critical seconds of operation. The "20" represents the oil's viscosity at operating temperature. It's thin enough to reduce internal friction, which actually helps you squeeze a little more fuel economy out of that V6.

While you can technically use 5W-20 if 0W-20 isn't available, Nissan suggests switching back to 0W-20 at the next oil change. Honestly, though, 0W-20 is so common now that you shouldn't have any trouble finding it at any local shop.

Synthetic vs. Conventional: Does it Matter?

Most 0W-20 oils on the market today are either full synthetic or a synthetic blend. For a 2018 model, full synthetic is the way to go.

Synthetic oil handles heat much better than conventional oil. Since the Pathfinder is often used for hauling families, groceries, or even towing a small trailer, the engine can get pretty warm. Synthetic oil won't break down as fast under that stress. It also keeps the inside of your engine cleaner by preventing sludge buildup. If you want that Pathfinder to hit 200,000 miles, don't cheap out here—grab the high-quality synthetic stuff.

Getting the Capacity Just Right

When you head to the store, you'll usually find oil sold in individual 1-quart bottles or large 5-quart jugs. Since the 2018 nissan pathfinder oil type and capacity calls for 5.1 quarts, buying just one 5-quart jug won't quite put you at the "Full" mark on the dipstick.

I usually recommend buying one 5-quart jug and one extra individual quart. Use the big jug first, then add just a tiny splash from the smaller bottle. Keep the rest of that extra quart in your trunk. It's always handy to have a little bit of oil on hand for top-offs between changes, especially as the vehicle gets older.

Don't Forget the Filter

Your oil is only as clean as the filter it's running through. For the 2018 Pathfinder, you want a high-quality spin-on filter. When you're looking at the shelf, you'll see brands like Fram, Mobil 1, or Wix.

A little pro tip: before you screw the new filter on, take a finger and smear a little bit of fresh oil onto the rubber gasket at the top of the filter. This helps it create a perfect seal and makes it much easier to remove the next time you change your oil. If you put it on dry, that rubber can bake onto the metal, and you'll be fighting with it six months from now.

Steps for a Successful DIY Oil Change

If you're planning to do this yourself, it's a pretty straightforward job. The Pathfinder has decent ground clearance, but you'll still likely want some ramps or a jack and jack stands to make life easier.

  1. Warm it up: Let the engine run for a few minutes. Warm oil flows much faster than cold, thick oil.
  2. Drain the old stuff: Find the drain plug on the oil pan. Make sure you have a drain pan that can hold at least 6 quarts.
  3. Swap the filter: While the oil is draining, unscrew the old filter. Be prepared for a little bit of a mess—oil always seems to hide in the filter.
  4. Replace the plug: Don't forget to put the drain plug back in! It sounds obvious, but everyone forgets once. Check the crush washer on the plug; if it looks flattened or cracked, spend the two dollars to get a new one.
  5. Fill it up: Pour in your 5.1 quarts of 0W-20.
  6. Check the level: Start the engine for a minute, let it circulate, then turn it off. Wait a couple of minutes for the oil to settle back into the pan, then pull the dipstick. It should be right between the two dots.

Resetting the Maintenance Light

Once you've got the 2018 nissan pathfinder oil type and capacity sorted out and the fresh oil is in, you'll probably have a nagging light on your dashboard telling you that maintenance is due. You don't need a computer or a mechanic to fix this.

You can reset this through the vehicle information display using the buttons on your steering wheel. Just navigate to the "Settings" menu, find "Maintenance," select "Oil and Filter," and then hit "Reset." It's a satisfying way to end the job and keeps your schedule on track for the next 5,000 to 7,500 miles.

How Often Should You Change It?

Nissan typically suggests an interval of 5,000 miles or 6 months, whichever comes first, especially if you do a lot of "severe" driving. In the world of car manuals, "severe" driving includes things like short trips (under 5 miles), idling in traffic, or driving in dusty conditions. Basically, if you live in a city or have a normal commute, you fall into the severe category.

If most of your miles are easy highway cruising, you might be able to push it closer to 7,500 miles, but with the VQ35DD engine, I've always found that 5,000 miles is the "sweet spot" for keeping everything pristine.

Wrapping Things Up

Taking care of your Pathfinder doesn't have to be a headache. As long as you stick to the recommended 2018 nissan pathfinder oil type and capacity—specifically 5.1 quarts of 0W-20 synthetic—you're doing exactly what your engine needs to stay healthy.

Whether you're doing it in your driveway or just want to make sure the local quick-lube shop is putting the right stuff in, being informed is the best way to protect your investment. Keep that oil clean, keep an eye on the level, and your Pathfinder will likely keep hauling you around for many years to come.
