If you want your vehicle to run, you have to make sure it has fuel. If you are a new Bentley owner and need to know how to put gas in the car, we can help you. We researched this luxury vehicle from multiple professional sources so you'll know what to do.
To gas up a Bentley, you'll need to do the following steps:
- Turn the engine off.
- Press the fuel filler door.
- Select the recommended fuel grade.
- Refuel your vehicle.
Now that we know how to put gas in a Bentley, we'll take a look at each step so you'll know for sure what it involves. You might also be curious about how large a Bentley's fuel tank is or if a Bentley has good fuel economy. For the answers to these questions and more, read ahead in this post and see what our research has uncovered.
Putting Fuel In Your Bentley
Getting your Bentley refueled takes no time at all. It's all a matter of getting the gas door open and selecting the proper fuel. Once you've pulled in next to the gas pump, you'll be ready to get started.
Turn the engine off
Before you even think about dispensing fuel from the pump, you will need to turn off the engine. Filling up a car that's running greatly increases the risk of fire.
Switch the engine off. It's also recommended to touch a metal surface before handling the gas pump so that any static electricity charge that has built up on your body can be eliminated. Though it might be hard to believe, a small static spark can ignite the fumes while you're filling up the tank.
For this reason, you should never re-enter your vehicle while it is fueling. Doing so will only give static electricity a chance to adhere to your body again.
Press the fuel filler door
The fuel filler door will not open by hand. You will need to press a button to release its catch. This button is located on the door control panel of the Bentley.
Gently press the button to release the door. If it's iced over on the outside of the vehicle, you might need to gently press the fuel door in if it will not open after the button is pushed. This will loosen the ice and should let the door open when the release button is pushed again.
Select the recommended fuel grade
You don't want to put just any fuel into the Bentley's gas tank. The owner's manual will list the proper grade you will need to select each time you fill it up.
Later in this post, we'll cover the recommended fuel grades. For now, know that a Bentley will need high-octane gasoline to operate at its best.
Refuel your vehicle
Once the fuel has been selected and the fuel door is open, you'll be ready to twist off the gas cap and fill up the tank. For safety's sake, never walk away from a vehicle that is being gassed up. Stay near the pump and outside your car until it has finished filling up.
Aside from the risks of fire, you will need to be on hand in case of accidental spillage. Being close by will allow you to shut off the pump if the automatic shutoff fails, or if there are other issues.
How Big Is The Fuel Tank On A Bentley?
Knowing how large your fuel tank is will let you budget fill-up costs. The size of a Bentley's fuel tank is going to vary based on the model year, the model itself, and sometimes even the trim level selected.
Let's take a look at the fuel tank sizes for all of the 2023 Bentley models. If you have an older model, you can always locate the tank size in the owner's manual.
Bentley fuel tank size by model
The 2023 Bentley Bentayga has a fuel tank that holds 22.5 gallons. The hybrid model has a fuel tank capacity of 19.8 gallons.
The 2023 Bentley Continental GT has a fuel tank capacity of 23.8 gallons.
The 2023 Flying Spur model has a tank size equal to the Continental GT, at 23.8 gallons. The hybrid model of the Flying Spur has a much smaller tank, at only 21 gallons.
Will A Bentley Get Good Gas Mileage?
A high-performance vehicle will typically not get the fuel economy that other classes of cars will enjoy. But the folks in the market for this type of car aren't looking for miles per gallon as a selling point.
Instead, they want a luxury car that purrs on the roadways with great bursts of power and top-notch interior comfort and amenities.
A Bentley will get a minimum of 14 miles per gallon on the highway up to a maximum of 18. If you are considering a hybrid, these do better in this area. A Bentley hybrid can get as many as 22 miles per gallon.
The mileage you will get in a Bentley will vary across models and trim levels. How you drive the vehicle will also directly impact how well the fuel economy will be.
What Type Of Fuel Does A Bentley Need?
A luxury, high-performance vehicle will not run its best on just any fuel type. For this model, you will need to be sure that you only put high-octane gasoline in its tank. For U.S. owners, this can be a bit confusing as the manual calls for 98 RON fuel to be used.
98 RON translates to 91 octanes in the States. Remember that this is the minimum octane rating that should be used in this make of vehicle. Gasoline with an octane rating of 93 will also suffice and give the car a bit better fuel economy and optimum performance.
What Happens If I Use Low-Octane Gasoline In A Bentley?
Failure to use the correct octane rating in its engine can also do lasting harm to the vehicle.
While the list below isn't all-inclusive, it will give you a general idea of why you should only use recommended octane ratings in high-performance vehicles. When in doubt, check your owner's manual for the type of fuel your vehicle needs.
Using low-octane fuel in a Bentley will make its fuel economy suffer
The harder an engine has to work, the more fuel it will burn. Inside a high-performance engine, the fuel is ignited at a greater compression of air in the cylinders. This gives the engine greater bursts of power.
A high-octane fuel is engineered to ignite with this compression. If low-octane fuel is used, the fuel will ignite too soon, causing an imbalance in the cylinders.
This reduces the fuel economy by a noticeable amount.
Low-octane fuel will damage the engine
When the fuel is ignited too soon, a suffering fuel economy isn't the only thing you'll need to worry about. This premature ignition will damage the cylinders and other vital parts of the engine. Over time, the engine will begin knocking.
These violent knocks are more than just startling sounds. The force of these knocks will damage the engine, eventually leading to you needing to replace the cylinders.
A Bentley's performance will suffer if the proper fuel isn't used
The reason a high-octane fuel is needed is so that the engine gets a more powerful burst when the fuel/air mixture explodes inside the engine's cylinders. This will propel the vehicle quicker and smoother.
If you do not use premium fuel, these bursts will not happen. The high-performance vehicle you've spent so much money on is now not operating at its fullest. You'll not be able to climb hills as quickly, and you'll notice that the vehicle has lost a good amount of its acceleration.
Putting fuel in a Bentley is quick and easy. Just be sure to use the proper fuel. Never fill a gas tank with the vehicle's engine running, as it can spark a fire. Know what grade of fuel you'll need, and only use what the manufacturer recommends.
