Questions To Ask Before a Jeep Engine Oil Change

Before you grab your Jeep Wrangler oil and start draining the fluids, there are some questions you need to evaluate. First, what oil is currently running in your Jeep? Is this the recommended oil as per the owner's manual, or do you need to make a change? Additionally, it would be best if you considered your Wrangler's age and the temperature your engine operates at. All of these factors will adjust what type or quality of motor oil you want to use for your Jeep.


Choosing a Quality Engine Oil for Your Jeep Wrangler

Engine Compatibility

The person looking to find the best oil for 2006 Jeep Wrangler 4.0 won't search for 2013 Jeep Wrangler oil. You must find the oil that's compatible with your Jeep engine and requirements. If it's an older engine with a lot of miles, it will require more protection.

Oil Type

In relation to the point above, there are several motor oil types. You can choose conventional, synthetic blend and full synthetic oils. Some oils are specifically created to add lubricity to high-mileage engines.

Oil Specs

If you want a high-quality Jeep Wrangler oil type, it's vital to look for various certifications. The API certification is given by the American Petroleum Institute, while the European Automobile Manufacturers' Association provides the ACEA certification.

Oil Viscosity

Engine oil viscosity tells you how easily the oil pours at a specific temperature. Thinner oils feature a lower viscosity to pour easily when the temperatures drop. In comparison, the thicker oil features a higher viscosity, maintaining thickness while operating at higher temperatures and under more stress.

Additives

If you are currently using one of the best engine oil additives in your motor, you want to choose the best oil brand for Jeep Wrangler that is compatible. The majority of Jeeps don't require an additive, but there are times when it's appropriate, such as with an older engine, motor knocking, or if the SUV has noisy lifters.

Some people prefer to use the oil directly from the manufacturer, which is why this Mopar oil is so popular.

However, Chrysler engineering specifically made this oil to work with the Jeep engines.

It's high-quality motor oil reduces piston deposits, increases fuel economy, reduces oil consumption, and improves oxidation protection. It's the type of oil that comes in your Jeep when you pick it up from the dealer.

However, you don't have a lot of options when it comes to sizing. In fact, the only way to purchase this motor oil is in a five liter container. This might be more or less than what you actually need, forcing you to store the oil for a later time. If only OEM will do, you will want to pay more for Mopar.


Benefits of Using The Best Engine Oil for a Jeep Wrangler

With the best engine oil for a Jeep Wrangler JK, you receive several benefits. First, the right oil and additive combination can improve engine efficiency. When the motor is running as it should, you can also expect increased mileage. Plus, with a long-lasting engine oil and oil filter, you can go longer without the need for a Jeep Wrangler oil change.


Single Grade vs. Multigrade Oil: Does it Matter in Jeep Engines?

There is a significant difference between the single grade and multigrade engine oil. Multigrade oil has two varying flows; one when the engine is warm and another when it's cold. Multigrade oil begins thinner and moves up in specification when it gets warm. The majority of automotive engines require a multigrade oil, while the single grade is designed for smaller machinery, such as lawn equipment. 


How to Change Oil on Jeep Wrangler Engines

Most synthetic oil and filters should be changed every 7,500 to 10,000 miles, while conventional oils should be replaced every 3,000 to 5,000 miles. Performing your own oil change is simple and will save you money.

  1. 1
    Park your vehicle on level ground and leave the engine slightly warm.
  2. 2
    Place a pan under the drain plug and remove it.
  3. 3
    Allow the oil to drain.
  4. 4
    Remove the old oil filter with a wrench and replace it with a new one.
  5. 5
    Replace the drain plug and fill your Jeep with the proper amount of oil.
  6. 6
    Run the engine and recheck the levels before driving.

You will also need to know how to reset the oil change indicator system.

To stop the engine from knocking, switch to a higher octane fuel or use fuel additives to clean out the combustion chamber. You might also need new spark plugs or check the engine timing.
