What to Know Before Buying Oil for Your Wrangler

Before you grab a bottle of cheap, off-brand oil for your Wrangler, you have several factors to consider. By understanding these various aspects, you’ll have a better idea of the type of oil you need for premier performance.

Conventional or Synthetic?

You may have been asked by a mechanic whether you want conventional or synthetic oil for your Wrangler. This is an important difference to comprehend, especially if you’re topping off the oil or changing it yourself.

Conventional oil is the cheaper option. Though there’s nothing wrong with using conventional oil in your Jeep, it doesn’t have nearly the lubrication power of synthetic oil. However, you’re going to pay two to three times more for synthetic oil, so factor that into your budget.

And those are just the two most common types of motor oil. You also have a synthetic blend and high mileage to choose from, making your research all the more important. Realistically though, any full synthetic will be a good bet.

Weather Conditions

If you live in an area with extreme weather or temperature changes, this will affect what oil you purchase. Some oils work well in high or low temperatures, while other types of oil become more viscous in temperature change, making them a poor choice for engine lubrication in cold weather.

Building upon this idea, you may have seen an oil rating such as 5W30. This first number describes the viscosity (thickness of the oil) at low temperatures and the W refers to winter in reference to this. The lower the number, the better the oil performs at cold temperatures.

The second number describes how well the oil performs in higher temperatures. The higher this number is, the thicker the oil stays when warm, and the better it holds up in sizzling weather.

Driving Style Matters

Are you an avid off-roader or you tackle the urban jungle? If so, you’re probably putting your engine to the test. High-revving on one side and the start-and-stop of city driving can put extra stress on your vehicle. As a result, you’ll need high-performance engine oil to ensure proper performance. In most cases, some sort of synthetic is the better option, especially if you’re driving on a regular basis.

Age Matters

Jeep owners all love their vehicles. Whether yours is 20 years old or 2 years old, your adoring gaze will never waver. However, what you put into your Jeep’s engine is important with respect to the age of the vehicle.

Older vehicles (over 75,000 miles) might need a dose of high-mileage motor oil, which comes with additives designed to improve the longevity of the engine. Younger vehicles may not require special oil, and even old Jeeps that run like new can still survive on a high-quality synthetic oil.

No matter which oil you ultimately choose, the age of the vehicle needs to factor into your decision.

Oil Types for Wrangler Explained

As mentioned above, there are several oil types for the Jeep Wrangler. Which one you select has to do with the age of your vehicle, your climate, and your budget. Here are each of the most common ones for your convenience.

Conventional Oil

While oil companies push synthetic oil as the superior product, conventional has its place among certain Jeep Wranglers. Older models of the Wrangler, including the Wrangler YJ and Wrangler TJ, were actually manufactured to use conventional oil and were filled with conventional oil when they came off the assembly line. If you don’t push your Jeep too much and you change your oil regularly, conventional oil is a cost-effective choice.

Valvoline 881150

Full Synthetic Oil

Full synthetic oil is a more modern option compared to conventional oil. The main difference between conventional and synthetic oil is that more of the impurities have been removed, giving it superior lubrication, durability, and performance over conventional oil.

Because of this oil’s superb performance, it’s a great choice for off-roaders and owners of newer Jeep Wranglers, such as the Wrangler JL and Wrangler JK. However, it’s far more expensive than either synthetic blend or conventional motor oils.

Synthetic Blend Oil

As the name would suggest, synthetic blend oil is a mix of synthetic base oil and conventional motor oil. Essentially, it’s a mid-grade fuel in terms of performance and price. If you don’t want to pay full price for synthetic motor oil, a blend is an ideal choice. While not necessarily recommended for the new Wrangler JL, it’s a good balance for occasional off-roaders and everyday drivers of the TJ, YJ, and JK models of the Wrangler.

High-Mileage Oil

Again, the name high-mileage suggests what it’s for: vehicles with 75,000 miles or more. If your Wrangler has 75,000 miles or you notice that your Wrangler is starting to break down on occasion, high-mileage oil provides additives such as minimizing oil leaks, reducing emissions and smoke, and restoring seals. On average, it’s about the same price as a synthetic blend and is the ideal choice for older-model Jeep Wranglers.

Keep Your Wrangler Running Smooth With the Perfect Choice of Oil

Whether you go with synthetic, a blend, or conventional oil in your vehicle, don’t go with some off-brand. Instead, choose a highly rated oil that provides excellent performance and lubrication. For just a few extra bucks, you can improve the longevity of your beloved Wrangler.

People Also Ask

Because of the sheer number of motor oil choices for your Wrangler, you may have some additional questions regarding which one to select. To alleviate your concerns, here are some of the common questions people also ask.

Do Jeep Wranglers Require Synthetic Oil?

Not all Jeep Wranglers require synthetic oil. Some older models can do without it, and if you’re diligent about changing your oil, even a conventional should do the job. However, if you live in a place with extreme temperatures (cold or hot), or you want to wait for 7,000 to 10,000 miles between oil changes, synthetic oil is the better option.

Can I Use 5W30 Instead of 5W20 in My Jeep?

5W20 motor oil is slightly thinner than 5W30 when your engine is running. But if you accidentally picked up a bottle of 5W30 motor oil instead of 5W20, it shouldn’t hurt anything. In addition, some Wrangler enthusiasts believe that the 5W30 provides better lubrication while the 5W20 can increase gas mileage by a tad due to its thinner consistency.

What Brand Oil Does Jeep Recommend?

Every new Jeep that rolls off the assembly line comes with Pennzoil synthetic motor oil. As a result, Jeep recommends Pennzoil motor oil for every oil change.
