what type of oil for jeep wrangler

If you own a Jeep Wrangler, you’d know how important it is to regularly change its engine oil. But, a very common question Jeep owners ask is “What type of oil for Jeep Wrangler should I use?”.

If you are using your Jeep in an extremely cold environment and have the budget for it, synthetic engine oil is for you. Whereas, if your Jeep runs in normal or hot weather and you are budget conscious, conventional engine oil would be a more cost-effective option.

The function, longevity, and endurance of your Jeep’s engine depend on the type of oil and how frequently you change it. So, you can’t afford to not put it on your priority list. Otherwise, you’d be reducing your engine’s lifespan.

In this article, we talk about:

  • Types of Jeep Wrangler oils
  • Which engine oil should you use for your Jeep’s engine
  • And, more

Let’s dive in.

What Type Of Oil For Jeep Wrangler

There are essentially three types of engine oils you can use in a Jeep Wrangler:

  1. Regular oil
  2. Fully synthetic

Let’s clarify something right off the bat: If you own a Jeep Wrangler, the most important thing is to change its engine oil regularly.

Your engine’s life and performance depend on it. While the manufacturer of your vehicle specifies how often you need to change its oil, the recommended range is 3000 – 5000 miles (more on this later).

They won’t specify the type of oil; it can be fully synthetic, a blend, or conventional. Your ride’s engine will keep on working if you change its oil at specified intervals. It won’t fail by using a particular kind of oil.

The point is: There is no hard and fast rule here; but, the type of oil you should be using for your Jeep Wrangler’s engine may depend on several factors. These include:

  • The weather conditions you are driving your Jeep in (Is it extremely cold/hot?)
  • Would you prefer a relatively cost-effective engine oil or is money not a problem for you?
  • What type of engine oil have you been using up until now?

Once you have the answers to all those questions, you’ll be in a position to select the right engine oil for your Jeep Wrangler. The type of oil that can effectively protect your ride’s engine and prolong its life.

Synthetic VS Conventional Jeep Engine Oil

To better understand how one type of oil compares to the other, let’s get a bit technical.

Synthetic oil is made of uniform-size molecules, which makes it more resistant to extreme temperatures.

It also offers better shear strength, as a result, it can endure higher shear forces without breaking down.

Moreover, synthetic oils are generally free of contaminants like wax and sulfur; something you can’t say about conventional oil.

Also, it tends to stay clean for a longer period as compared to conventional oil, which is why its changing interval can be a bit longer.

But, normal oil is cheaper and gets the job done effectively.

Suitable Engine Oil for Extreme Cold Temperatures

If you are using your Jeep in extremely cold weather conditions, synthetic oil with a 0W-30 rating would be suitable.

This is because synthetic oil has low viscosity, helping it to flow better. This allows easier starts and smoother shifts in colder weather.

Suitable Engine Oil for Normal Weather

In normal or hot weather conditions, conventional engine oil works fine. Normal engine oils are effective at protecting your engine and are not that expensive either.

Moreover, one of the reasons why Jeep owners shift to conventional engine oil is because the synthetic one leaks.

So, if your oil synthetic engine oil starts leaking, try switching to the normal oil.

It’s not a proven fact though; there might be other reasons for leakage, too.

When Should You Change Your Jeep Wrangler’s Oil?

Most manufacturers recommend Jeep owners to change their conventional engine oil between the 3000 – 5000 miles range.

Some would suggest that you change it as soon as your Jeep’s mileage hits 3000 miles, whereas some allow the flexibility to go up to 5000 miles.

But, the general rule is, you want to replace your Jeep Wrangler’s old oil within 3000 – 5000 miles of running it.

If you were to ask us, we’d suggest changing it after 3000 miles, just to be on the safer side. Synthetic oil tends to last longer, so you can even go over 7000 miles with it.

Combustion Contaminants

There are multiple contaminants that degrade your engine oil over time.

  • The cooling system (water plus coolant)
  • Soot
  • Fuel
  • Acid and sludge

Your Jeep Wrangler’s engine oil becomes contaminated and viscous over time because of all those factors.

What Type of Oil for My Jeep Wrangler?

To be completely honest, you don’t need to be too cautious about the type of engine oil; the best type of oil for your Jeep Wrangler is clean oil.

So, the more important thing is the oil changing interval; if you think your oil has gotten muddy after approximately 3000 miles, go for the upgrade.

And, the recommended oil change duration/interval remains the same irrespective of its brand.   

And, that applies if you are using your Jeep for:

  • Off-roading
  • City driving
  • Towing
  • Dry conditions

What Type of Engine Oil Does a Jeep Wrangler Have?

When you purchase a Jeep from the dealership, it’d have the regular engine oil. Your dealership will also suggest changing the engine oil after 3000 miles of usage.

Just keep in mind the differences before making a decision. Overall, synthetic oil works longer and is better in performance, especially in colder weather, but is expensive, too. If budget is an issue, you can always go for conventional oil.
