Difficulty, time, and cost are estimates when this guide gives them. Torque is a cited figure, or it is left off.

The 2.0L calls for Mopar API SN PLUS SAE 5W-30 full synthetic meeting MS-13340. An equivalent full synthetic SAE 5W-30 may be used if it meets API SN PLUS.
The 3.6L calls for API Certified SAE 0W-20 meeting MS-6395. The filler cap also shows the recommended viscosity.
This sheet is from publication 18JL-126-AC, the all-new 2018 Wrangler JL owner's manual. It is not the 2019 book and it is not the JK. No drain-plug torque is printed, so none is added.
