What gas type you can fill in the Jeep Wrangler depends on the kind of engine you carry in the Wrangler. Jeep recommends a regular gasoline/petrol octane rating of 87 but using premium gasoline 91 or higher-octane to get optimal performance.
The older generation Jeep Wrangler YJ, JK, and TJ have 2.4L, 2.5L, 4.0L, 4.2L, 3.8L, and 3.6L engines. For these engines, regular unleaded gasoline with an octane rating of 87 is recommended.
In the new Jeep Wrangler JL for a 3.6L and 2.0L turbocharged engine, the regular unleaded gasoline having an 87 octane rating is recommended. For a 6.4L engine, premium unleaded gasoline having an octane rating of 91 or higher is recommended. And if the Jeep Wrangler has a 3.0L engine, it will run on diesel fuel.
