While it may seem straightforward, there are important safety steps, fuel type considerations, and best practices that can help you avoid costly mistakes—like using the wrong fuel or damaging your vehicle’s engine.

In this comprehensive guide, you’ll learn everything you need to know about refueling your vehicle safely and efficiently. From identifying the correct fuel type to understanding pump mechanics and staying safe at the gas station, we’ve got you covered. Whether you’re a new driver or just want to brush up on best practices, this guide will ensure you’re confident every time you pull up to the pump.

Let’s get started!

Step 1: Know Your Vehicle’s Fuel Requirements

Before you even leave your driveway, the most important step is knowing what kind of fuel your car or SUV needs. Using the wrong type can cause engine damage, reduce performance, and void your warranty.

Check the Owner’s Manual

Your vehicle’s owner’s manual is the best source of truth. Look for the fuel recommendation section, which will specify whether your vehicle requires regular unleaded (87 octane), mid-grade (89 octane), premium (91–93 octane), or diesel fuel.

For example, many luxury SUVs like the BMW X5 or Mercedes-Benz GLE require premium fuel for optimal performance. On the other hand, most compact SUVs like the Honda CR-V or Toyota RAV4 run perfectly fine on regular unleaded.

Look for the Fuel Cap Label

Most vehicles have a label on or near the fuel door that indicates the recommended fuel type. It’s usually a small sticker with text like “Premium Unleaded Only” or “Diesel Fuel Only.” This is a quick visual cue when you’re at the pump.

Understand Octane Ratings

Octane measures a fuel’s resistance to knocking or pinging during combustion. Higher octane fuels are more stable under high pressure and heat—important for high-performance or turbocharged engines.

Using a lower octane fuel than recommended can cause engine knocking, reduced fuel efficiency, and long-term damage. However, using a higher octane fuel than required won’t improve performance or efficiency in most standard engines—it’s just a waste of money.

Diesel vs. Gasoline: Don’t Mix Them Up

Diesel fuel is thicker and has a distinct smell. Diesel engines compress air to ignite the fuel, while gasoline engines use spark plugs. Putting diesel in a gasoline engine (or vice versa) can cause serious damage.

Diesel fuel nozzles are larger in diameter, so they typically won’t fit into gasoline fuel tanks. However, gasoline nozzles can fit into some diesel tanks—so always double-check before fueling. If you accidentally put the wrong fuel in your tank, do not start the engine. Call a tow truck and have the fuel drained immediately.

Step 2: Choose the Right Gas Station

Not all gas stations are created equal. While convenience is important, choosing a reputable station can help ensure fuel quality and safety.

Look for Well-Lit, Busy Stations

Stations that are well-lit and frequently used are more likely to have fresh fuel and better maintenance. Avoid isolated or poorly maintained pumps, especially at night.

Consider Brand Reputation

Major brands like Shell, Exxon, Chevron, and Costco often have stricter fuel quality controls. They may also offer rewards programs or discounts for members.

Use Apps to Find the Best Prices

Apps like GasBuddy, Waze, or Google Maps can help you find the cheapest fuel near you. Some apps even show real-time prices and user reviews of station cleanliness and service.

Check for Payment Options

Make sure the station accepts your preferred payment method—credit card, debit card, mobile pay, or cash. Some stations offer discounts for paying inside or using their app.

Step 3: Prepare to Fuel Up

Once you’ve arrived at the pump, take a moment to prepare. A little planning can make the process smoother and safer.

Park Correctly

Pull up to the pump so that your fuel door is on the same side as the pump. Most vehicles have the fuel door on the driver’s side, but some SUVs and trucks may have it on the passenger side.

Leave enough space between your vehicle and the pump to avoid scratching your bumper or door. Also, make sure your vehicle is in “Park” (for automatics) or in gear with the parking brake on (for manuals).

Turn Off the Engine

This is a critical safety step. Never refuel with the engine running. Running engines can create sparks, and fuel vapors are highly flammable. Turning off the engine eliminates this risk.

Remove Keys and Electronic Devices

Take your keys out of the ignition and avoid using your phone while fueling. Although rare, static electricity from handling your phone or re-entering your vehicle can ignite fuel vapors.

Ground Yourself

Before touching the fuel nozzle, touch a metal part of your vehicle’s body (like the door frame) to discharge any static electricity. This simple step reduces the risk of a spark.

Step 4: Open the Fuel Door and Cap

Now it’s time to access your fuel tank.

Locate the Fuel Door Release

Most vehicles have a fuel door release lever inside the cabin, usually near the driver’s seat or on the floor. In some SUVs, it may be on the center console or under the steering column.

Press or pull the lever to unlock the fuel door.

Open the Fuel Door

Gently push or pull the fuel door open. Some vehicles have a spring-loaded door that pops open when released.

Remove the Fuel Cap

Twist the fuel cap counterclockwise to remove it. Most caps are tethered to the fuel door to prevent loss. Place the cap in a safe spot—like the fuel door ledge or your lap—so it doesn’t get dirty or lost.

Some newer vehicles have capless fuel systems. In these cases, you’ll see a small flap that opens when you insert the nozzle. No cap to remove!

Step 5: Select the Correct Fuel Grade

At the pump, you’ll see several fuel options. Choose the one that matches your vehicle’s requirements.

Identify the Fuel Buttons

Pumps typically have buttons labeled “Regular,” “Mid-Grade,” “Premium,” and “Diesel.” Some may use numbers (87, 89, 91, 93) to indicate octane levels.

Press the Correct Button

Press the button for the fuel type your vehicle needs. The pump will light up the selected option.

If you’re unsure, refer back to your owner’s manual or the label near your fuel door.

Insert Your Payment Method

Swipe your credit or debit card, tap for contactless payment, or insert cash if the pump accepts it. Follow the on-screen prompts to complete the transaction.

Some pumps require you to insert your card before selecting fuel, while others let you choose fuel first. Pay attention to the instructions on the screen.

Step 6: Insert the Nozzle and Begin Fueling

Now it’s time to add fuel to your car or SUV.

Remove the Nozzle from the Pump

Grasp the fuel nozzle firmly and pull it out of the pump holster. Make sure the hose isn’t twisted or kinked.

Insert the Nozzle into the Fuel Tank

Push the nozzle fully into the fuel tank opening. For capless systems, press the nozzle against the flap until it opens.

Squeeze the Handle to Start Fueling

Press the lever on the nozzle to begin fueling. Most nozzles have a latch that allows you to lock the handle in place, so you don’t have to hold it the entire time.

Monitor the Fuel Level

Keep an eye on the pump display to see how much fuel you’re adding and the total cost. Most drivers fill up until the pump automatically shuts off.

Don’t Top Off

When the pump clicks off, stop fueling. Attempting to “top off” the tank can cause fuel to spill into the evaporative emissions system, which can damage sensors and lead to expensive repairs.

Overfilling can also cause fuel to leak onto the ground, creating a fire hazard and environmental issue.

Step 7: Finish Fueling and Secure the Tank

Once fueling is complete, it’s time to wrap up.

Release the Nozzle Handle

If you used the latch, release it and allow the handle to return to its resting position.

Remove the Nozzle

Gently pull the nozzle out of the fuel tank. Give it a slight twist to help break the seal.

Replace the Fuel Cap

Screw the fuel cap back on clockwise until it clicks. For capless systems, simply close the flap.

Close the Fuel Door

Push the fuel door shut until it latches securely.

Return the Nozzle to the Pump

Place the nozzle back into the pump holster. Make sure it’s seated properly and the hose isn’t tangled.

Step 8: Take Your Receipt and Drive Safely

Before driving off, take a moment to complete the process.

Retrieve Your Receipt

Most pumps print receipts automatically. If you paid with a card, you may also receive an electronic receipt via email or app.

Check Your Fuel Gauge

Start your vehicle and check the fuel gauge to confirm the tank is filling as expected.

Store Your Receipt

Keep your receipt in your glove compartment or wallet. It’s useful for expense tracking, warranty claims, or identifying fuel quality issues.

Drive Responsibly

Now that you’re fueled up, drive safely and enjoy the ride!

Troubleshooting Common Fueling Issues

Even experienced drivers can run into problems at the pump. Here’s how to handle common issues:

The Pump Won’t Start

– Make sure your engine is off.
– Check that your payment method was approved.
– Try selecting the fuel grade again.
– If the problem persists, try a different pump or contact station staff.

The Nozzle Keeps Clicking Off

This usually happens when the fuel tank is full or the vent system is blocked.
– Stop fueling immediately.
– Don’t try to force more fuel in.
– Check for kinks in the filler neck or a clogged vent hose (rare, but possible).

Fuel Smell After Fueling

A faint smell is normal, but a strong odor could indicate a leak.
– Check that the fuel cap is tight.
– Inspect the fuel door and tank area for spills.
– If the smell persists, have your vehicle inspected by a mechanic.

Wrong Fuel Added

If you accidentally put the wrong fuel in your tank:
– Do not start the engine.
– Call a tow truck to have the fuel drained.
– Contact your insurance or roadside assistance for help.

Tips for Saving Money and Staying Safe

Use Rewards Programs

Many gas stations offer loyalty programs that give you discounts, free car washes, or points redeemable for groceries or gift cards. Sign up for apps like Shell Fuel Rewards, Exxon Mobil Rewards+, or Costco Membership to save.

Fuel Up During Cooler Hours

Fuel is denser in cooler temperatures, so you get more energy per gallon when you fill up early in the morning or late at night.

Maintain Your Vehicle

A well-maintained engine runs more efficiently. Regular oil changes, air filter replacements, and tire pressure checks can improve fuel economy.

Avoid Idling

Idling wastes fuel. If you’re waiting somewhere for more than 30 seconds (except in traffic), turn off the engine.

Plan Your Route

Combine errands to reduce unnecessary driving. Use GPS apps to find the most fuel-efficient route.
