Selecting the Right Oil for Your Jeep Wrangler

When it comes to selecting the right oil for your Jeep Wrangler, it’s crucial to consider the manufacturer’s recommendations and the specific needs of your vehicle. For JK Wranglers equipped with the Pentastar 3.6L engine, Mopar recommends using either 5W-20 or 5W-30 oil, depending on the expected driving conditions. While both options are suitable, 5W-20 oil is generally recommended as it offers better fuel economy and optimized lubrication during cold starts.

It’s essential to ensure that the oil you choose meets or exceeds Chrysler Materials Standard MS-6395. This specification guarantees the oil’s quality and ensures compatibility with your Jeep’s engine. While Mopar, Pennzoil, and Shell are reputable and recommended brands, other oils that meet the manufacturer’s specifications will work just as well.

Recommended Oil Viscosity for Different Conditions

The recommended oil viscosity for your Jeep Wrangler varies depending on the climate and driving conditions you typically encounter. Here’s a breakdown:

Driving Conditions	Recommended Oil Viscosity
Normal driving in moderate temperatures	5W-20
Severe conditions (extreme cold or hot weather, off-roading, towing)	5W-30

Please refer to your owner’s manual for specific oil viscosity recommendations based on your driving situation.

Remember, regularly changing your Jeep Wrangler’s engine oil using the right oil filter and engine oil is essential to maintain optimal performance and extend the longevity of your vehicle.

The Oil Change Process for 2018 and Newer JL Wranglers

For 2018 and newer JL Wranglers with the 3.6L Pentastar V6 engine, the oil change process is quite similar to the older generation JK Wranglers. Follow these steps to change the oil in your JL Wrangler:

Park the Jeep on a level surface to ensure accurate oil measurement. Start the engine and let it run for a few minutes to warm up the oil, making it easier to drain.
Find the oil drain bolt underneath the vehicle. It is typically located on the oil pan. Place a drain pan beneath the bolt to catch the draining oil.
Using a suitable wrench or socket, carefully remove the drain bolt and allow the old oil to drain completely into the drain pan. Be cautious as the oil may still be hot.
While the oil is draining, locate the oil filter cap, which is typically located near the top of the engine. Remove the cap in a counterclockwise direction. Once removed, take out the old oil filter.
Before installing the new oil filter, lubricate the O-ring with a small amount of oil to ensure a proper seal. Insert the new filter into the filter housing and tighten the cap to the specified torque setting.
Once the oil has finished draining, reinstall the drain bolt and tighten it to the recommended torque specification. Be careful not to overtighten.
Now it’s time to add fresh oil to the engine. Refer to your owner’s manual or consult with a trusted mechanic to determine the recommended oil type and quantity for your specific JL Wrangler.
Using a funnel, pour the new oil into the oil filler port. Be sure to pour it slowly and carefully to avoid spills and overfilling. Check the oil level using the dipstick and add more if necessary.
Once you’ve added the correct amount of oil, replace the oil filler cap and tighten it securely. Give the engine a few moments to allow the new oil to settle.
Lastly, reset the oil change reminder on your JL Wrangler if needed. Consult your owner’s manual for specific instructions on how to reset the reminder.

Following these steps will ensure that your 2018 and newer JL Wrangler receives a proper oil change, promoting optimal engine performance and longevity.
