The Jeep Wrangler is known for its off-road capability and fun open-air driving experience. But like any vehicle, fuel efficiency is still a concern for Wrangler owners.
Choosing the right type of gas for your 2019 Jeep Wrangler is important to get the best performance and gas mileage. This article will cover Jeep’s recommended fuel type for both available engines, as well as tips to maximize your fuel economy.
Overview of Jeep Wrangler Engine Options
The 2019 Jeep Wrangler comes with two different engine options: a 2.0L turbocharged 4-cylinder or a 3.6L V6. The type of gasoline you use will depend on which engine you have.
2.0L Turbocharged Engine
The 2.0L turbocharged 4-cylinder engine requires premium unleaded gasoline with an octane rating of 91 or higher. This higher octane fuel allows the turbocharged engine to produce full performance without risk of detonation or knock.
You can also use regular unleaded gasoline with an octane rating of 87, but you may experience reduced performance and fuel economy. The engine computer will retard ignition timing to prevent knock, which reduces power output. For best performance, always use 91+ octane premium fuel.
3.6L V6 Engine
The 3.6L V6 engine is designed to run on regular unleaded gasoline with an octane rating of 87. This is the minimum octane rating recommended by Jeep.
You can also use premium 91+ octane fuel, but you will not see any benefit in performance or fuel economy. Since the V6 engine does not require high octane, you are just paying extra without reward.
Recommendation for Fuel Type
If you have the 2.0L turbocharged engine, use 91+ octane premium gasoline for best performance and fuel efficiency. The high octane prevents knock so the engine can operate at peak output.
If you have the 3.6L V6, regular 87 octane unleaded gasoline is recommended. No benefit is gained from using premium fuel in the V6.
| Engine | Recommended Fuel |
|---|---|
| 2.0L Turbo | 91+ Octane Premium |
| 3.6L V6 | 87 Octane Regular |
Factors That Impact Fuel Economy
While using the recommended fuel is important, there are many other factors that contribute to the fuel economy of your Jeep Wrangler:
- Driving habits – Aggressive acceleration and braking reduces MPG
- Speed – Driving at lower speeds increases MPG, highway speeds reduce it
- Load – Added cargo weight reduces fuel efficiency
- Tire pressure – Make sure tires are inflated to proper PSI
- Maintenance – Replace air filters, spark plugs, fluids when needed
- Accessories – Adding lights, lift kits, bumpers hurts MPG
- Terrain and road conditions – Off-roading lowers MPG
While premium fuel is recommended for best performance in the 2.0L turbo, keep these other factors in mind as well to maximize your gas mileage.
Where to Get Recommended Fuel
All major gasoline brands offer both regular 87 octane and premium 91+ octane fuel. Premium gasoline may not be available at all stations though. When planning long trips, locate stations along your route that offer premium to avoid issues.
Some gasoline brands recommended by Wrangler owners are Shell, Chevron, Exxon, and BP. Look for top tier detergent gasoline to help keep your engine clean.
Avoid no-name discount brands as they may mix in more ethanol or lack sufficient detergent additives. Poor quality gasoline can negatively impact performance and fuel economy in the long run.
Conclusion
To summarize, use 91+ octane premium gasoline in the 2019 Jeep Wrangler if you have the 2.0L turbocharged engine. 87 octane regular unleaded is recommended for the 3.6L V6.
Following the manufacturer’s fuel recommendations allows your Wrangler to deliver optimal performance and efficiency. Combine with smart driving habits for maximum mileage.
