Which Jeep Wrangler model years does this cover?

These oil specifications apply to every Jeep Wrangler built from 2012 through 2017 — the JK (2007–2018 platform; US 2012–2017 shown), off-road suv, solid front/rear axle (2-door; 4-door unlimited). Nothing in this specification changes between those model years. Pick your year for the engines it offered, what changed that year, and the problems recorded against it.

How many quarts of oil does a 2012–2017 Jeep Wrangler take?

6 quarts with a filter change. Fill to about 5.5 quarts, run the engine, then top up to the mark on the dipstick rather than pouring the full amount in at once.

What kind of oil does a 2012–2017 Jeep Wrangler take?

0W-20 meeting Chrysler MS-6395 / API SN, full synthetic (required, not merely recommended).

Can you use a different viscosity in a 2012–2017 Jeep Wrangler?

The manufacturer also permits 5W-20 (Acceptable substitute per some Mopar documentation if 0W-20 is unavailable). Anything outside that list is a decision you are making against the factory specification.

How often does a 2012–2017 Jeep Wrangler need an oil change?

Oil-life monitor determines interval, typically ~10,000 mi with full synthetic (normal); 5,000 mi (severe service, off-road, towing, frequent short trips). Short trips, towing, extended idling, and dusty or very cold conditions all put the vehicle on the severe-service side of that interval.

Common equivalents: Fram XG10060 (Ultra, spin-on), Wix 51334, Purolator L14459 (cartridge equivalent).
