The most common size is a 65mm oil filter wrench/socket for the 3.6L Pentastar engine’s spin-on oil filter; some brands use 64mm or 68mm, so have a backup strap wrench or adjustable filter tool just in case.
In the 2015 Wrangler Sport, which uses the 3.6-liter Pentastar V6, the oil filter is of the spin-on type and sits on the side of the engine. The outer diameter of the filter varies slightly by manufacturer, which is why many sources cite a 65mm wrench as the standard option. If you’re using a different brand of filter, check its packaging for the exact wrench size, or measure the filter’s outside diameter to select the correct tool. In tight spaces, a strap wrench or filter pliers often provide an easier grip than a socket wrench.
Engine and filter basics
The 2015 Jeep Wrangler Sport is equipped with a 3.6L Pentastar V6. The oil filter is a spin-on cartridge that threads into a filter base on the engine block. While the specific outer diameter of filters can vary slightly by brand, many filter manufacturers design their 3.6L filters to fit a standard 65mm removal tool. If your chosen filter is slightly smaller or larger, you may need a 64mm or 68mm wrench instead. Always confirm with the filter’s labeling or your owner’s manual.
Socket size and tools
The following summarizes typical tools used to remove the oil filter on this engine. It’s normal for variations to occur across brands and filter models.
- 65mm oil filter wrench/socket — the most commonly recommended size for the 3.6L Pentastar spin-on filter.
- 64mm or 68mm variants — some brands use filters that fall just outside the 65mm range; have these sizes on hand.
- Alternative tools — strap wrench, chain wrench, or dedicated filter pliers for tight spaces or hard-to-reach filters.
Having a few options on hand helps ensure you can remove the filter without damaging the housing or filter itself. If you’re unsure, start with a 65mm tool and switch to an alternative if it doesn’t seat properly.
Removal and replacement steps
Follow these steps to safely remove the old filter and install a new one on a 2015 Wrangler Sport with the 3.6L engine.
- Park on level ground, set the parking brake, and turn off the engine. If the engine was recently running, let it cool to avoid burns.
- Place a drain pan beneath the oil pan and remove the drain plug to drain the engine oil (and dispose of the used oil properly).
- Move to the filter area. If space is tight, use the appropriate 65mm filter wrench or a strap wrench to loosen the filter counterclockwise.
- Remove the old filter by hand once it’s loose enough, allowing any residual oil to drain into the pan. Wipe the mounting surface clean.
- Prepare the new filter by lightly coating the gasket with fresh engine oil. Install the new filter by hand until snug, then give it an additional ¾ to 1 full turn (per the filter manufacturer’s instructions).
- Reinstall the drain plug, refill the engine with the correct oil capacity and grade as specified in the owner’s manual, and start the engine to check for leaks. Recheck the oil level and top off if necessary.
When finished, clean up and dispose of the old filter and used oil according to local regulations. If you notice any leaks after the test run, tighten slightly or recheck the gasket seating.
Safety and tips
Always follow basic safety practices when performing an oil change. Use jack stands if you need to work under the vehicle, wear gloves to protect your hands, and keep oil away from heat sources. If you’re unsure about the correct filter size, consult the vehicle’s manual or contact a parts retailer with your exact filter brand and model number.
Summary
For a 2015 Jeep Wrangler Sport with the 3.6L engine, the standard oil filter wrench size is typically 65mm. Some brands may require 64mm or 68mm, so verify the filter you install. If space or fitment becomes an issue, a strap wrench or filter pliers provide a reliable backup. Always replace the oil filter with a new gasket lubricated with fresh oil, refill to the manufacturer’s specs, and check for leaks after starting the engine.
