The 2020 Jeep Wrangler Rubicon typically runs on regular unleaded gasoline with an 87 octane rating, which works perfectly for most models. However, if you’re driving the 2.0L turbocharged engine, switching to premium gas (91 octane or higher) can really boost its performance and power.
If you’re driving or thinking about getting a 2020 Jeep Wrangler Rubicon, you probably want to know the type of gas it uses. It’s an important question because the right fuel helps keep your engine in good shape and avoids long-term damage.
In this guide, I’ll walk you through the gas requirements for the 2020 Rubicon, why it matters, and throw in a few tips on how to save on fuel.
What Type of Gas Does the 2020 Jeep Wrangler Rubicon Use?
The 2021 Jeep Wrangler Rubicon is designed to run on regular unleaded gasoline with an octane rating of 87. This is the type of fuel you’ll find at most gas stations, so it’s easy to find. You won’t need to go for premium gas unless you’ve made aftermarket modifications or plan to push the vehicle in extreme off-road situations where you need a bit more performance.
When it comes to the fuel efficiency of a 2021 or newer Jeep Wrangler Rubicon, it really depends on which engine you have and whether it’s paired with a manual or automatic transmission. Let’s break it down:
For the 2021 Jeep Wrangler Rubicon with the 3.6L Pentastar V6 Engine:
When it comes to the 2020 Jeep Wrangler Rubicon and its fuel economy, here’s what you can generally expect:
3.6L Pentastar V6 Engine:
- Manual Transmission: You’ll get around 17 MPG in the city and 23 MPG on the highway. It’s solid for a vehicle designed for off-roading.
- Automatic Transmission: If you go for the automatic, you’ll see a slight improvement with about 18 MPG city and 23 MPG highway, making it a bit more efficient for city driving.
2.0L Turbocharged Inline-4 Engine:
- Manual Transmission: If you opt for this engine, you’ll get a nice boost in efficiency, with around 21 MPG city and 24 MPG highway.
- Automatic Transmission: Interestingly, the automatic version delivers the same fuel economy—21 MPG city and 24 MPG highway, so you’re not losing out on any performance or efficiency.
EcoDiesel 3.0L V6 (available on other trims):
- Automatic Transmission: For those who want even better fuel efficiency, the EcoDiesel version offers a more impressive 22 MPG city and 29 MPG highway, making it a great choice if fuel economy is a top priority.
Note: Keep in mind that these are averages, and your actual fuel economy could vary depending on a few factors, like your driving style, road conditions (especially if you’re hitting the trails), tire pressure, and how much gear you’re carrying. But overall, these numbers give you a pretty good idea of what to expect for your everyday driving needs.
Can You Use Premium Gas in the Rubicon?
Yes, you can absolutely use premium gas in the 2021 Jeep Wrangler Rubicon, but it’s not really necessary unless you have the 2.0L turbocharged engine or plan on tackling some tough off-road challenges. For everyday driving, regular unleaded gas works just fine and keeps things running smoothly.
If your Rubicon is equipped with the 2.0L turbocharged engine, though, premium gas (91 octane or higher) can help boost performance, especially when you’re dealing with hot weather or carrying heavy loads like towing. While the engine can handle regular gas, using premium allows it to perform at its best.
So, in a nutshell, while regular gas is great for most situations, premium fuel is a good choice for those looking to get the most out of their 2.0L turbocharged engine, especially when you’re pushing the limits.
Diesel Engine Note:
Just to clarify, the 2020 Rubicon doesn’t come with a diesel option. However, Jeep did offer a 3.0L Eco Diesel V6 in other Wrangler trims later in the year. So, if you’re driving one of those, diesel is the way to go, but for the Rubicon, you’re sticking with gas.
Why Does the Right Gas Type Matters?
Using the right type of gas in your Jeep Wrangler Rubicon is about more than just saving a few bucks—it’s actually key to keeping your engine healthy. When you use the right fuel, you’re not just protecting the engine, but you’re also improving fuel economy and reducing emissions, which is always a win for the environment. Plus, it helps prevent annoying issues like knocking or pinging, which can happen when your engine doesn’t get the fuel it needs, and that can cause damage over time.
Luckily, the 2021 Rubicon is designed to run just fine on regular 87 octane gas, so you don’t have to stress about choosing the wrong fuel. Just remember, the right fuel choice keeps your engine running smoothly and efficiently, ensuring it stays in top shape for the long haul.
Fuel Economy Tips for Jeep Wrangler Rubicon Owners:
While the Rubicon is an off-road champion, it’s not exactly the most fuel-efficient vehicle out there. But don’t worry, there are some simple things you can do to make the most out of every gallon:
- Keep your tires properly inflated – Low tire pressure creates more resistance and burns more gas.
- Avoid aggressive driving – Hard accelerations and sudden stops waste fuel.
- Lighten your load – If you’re not using your roof rack or heavy gear, take it off to save fuel.
- Use cruise control on highways – It helps you maintain a steady speed and saves gas.
- Stick to regular maintenance – A well-maintained engine runs more efficiently.
What Kind of Gas Does a Jeep Wrangler Rubicon Take?
So, to keep it simple, the 2021 Jeep Wrangler Rubicon runs on regular unleaded gasoline. If you have the 3.6L V6 engine, 87 octane regular gas is all you need. However, if your Rubicon is equipped with the 2.0L turbocharged engine, regular gas will still work fine, but for the best performance, premium fuel (91 octane or higher) is the way to go.
That said, it’s always a smart move to check your owner’s manual to confirm you’re using the right type of fuel for your engine. This ensures you’re getting the best out of your vehicle while helping maintain its performance over time.
Can I Put 87 Gas in My Jeep Wrangler?
