(1) Read the manual and (2) occasionally monitor the "oil life remaining" readout on the vehicle info display. (3) You should tell the service manager to use 5 quarts of 0W20.When should the first oil change occur? Should I be asking the service manager exactly what oil they are using?
The 0W-20 synthetic spec was updated to help keep the engine better lubricated after they went to the ESS stop/start systems. That's the story anyway.0w20 is available in full synthethic or synthetic blend. Better ask your dealer to confirm if they use full synthethic or a blend.
Question: does the 0w matter in warmer climates vs 5w? Let’s say you live in the southwest, does 5w20 perform the same as 0w20 in warmer climates?
The JK 3.6 called for 5w20. Has anything really changed in the JL 3.6 to require 0w20 or is Jeep just trying to improve mpg by using a “lighter” oil?
Exactly so ! My JK requires 05-20 , per the owners manual . Goes 90 mph with no effort .Not me! I plan to keep my baby til it can't go anymore lol.
