You’ll learn how to safely refuel your Nissan SUV, when and how to replace the fuel filter, and what tools and precautions are necessary. Whether you’re a new driver or a seasoned SUV owner, this guide ensures you can handle your vehicle’s fuel needs with confidence and safety.

By the end of this article, you’ll know exactly how to change gas in a Nissan SUV—safely, efficiently, and correctly.

Understanding What “Changing Gas” Means

Before diving into the steps, it’s important to clarify what “changing gas” actually involves. In everyday language, this phrase can mean two things:

1. **Refueling your Nissan SUV** – This is the most common interpretation. It means filling up your gas tank at a fuel station when the fuel level is low.
2. **Replacing the fuel filter** – Over time, the fuel filter can become clogged with dirt, rust, or debris, reducing engine efficiency. Replacing it is a form of “changing the gas system” to ensure clean fuel reaches the engine.

Both tasks are essential for maintaining your Nissan SUV’s performance, fuel economy, and longevity. This guide covers both, so you’re fully prepared no matter what your vehicle needs.

Part 1: How to Safely Refuel Your Nissan SUV

Refueling your Nissan SUV is a routine task, but doing it safely and correctly helps prevent accidents and keeps your vehicle running smoothly.

Step 1: Park Safely at the Gas Station

When you arrive at a gas station, follow these steps:

– Pull up to the pump so the fuel door is on the correct side (usually the left or right, depending on your model).
– Turn off the engine completely. Never refuel with the engine running—this is a major fire hazard.
– Remove the keys from the ignition or press the start button to ensure the vehicle is fully off.
– Engage the parking brake to prevent the vehicle from rolling.

Tip: If you’re unsure which side the fuel door is on, check your dashboard fuel gauge—it often has a small arrow pointing to the side of the vehicle where the fuel door is located.

Step 2: Open the Fuel Door and Cap

– Locate the fuel door release lever inside your vehicle. It’s usually on the driver’s side floorboard or under the dashboard.
– Pull the lever to open the fuel door.
– Twist the fuel cap counterclockwise to remove it. Some newer Nissan SUVs have a capless fuel filler system—if so, simply press the flap open.

Set the cap aside in a safe place, like the cup holder or on the pump, so you don’t lose it.

Step 3: Choose the Correct Fuel Type

Check your owner’s manual to confirm the recommended fuel type. Most Nissan SUVs, including the Rogue, Murano, and Pathfinder, are designed to run on:

– **Regular unleaded gasoline (87 octane)**
– **Top-tier detergent gasoline** (recommended for cleaner engine performance)

Avoid using premium fuel unless your specific model requires it. Using higher-octane fuel than necessary won’t improve performance and is a waste of money.

Never use diesel fuel in a gasoline-powered Nissan SUV—it can cause severe engine damage.

Step 4: Insert the Nozzle and Begin Fueling

– Select the correct fuel grade on the pump.
– Insert the nozzle fully into the fuel filler neck.
– Squeeze the handle to begin fueling. Most pumps have an automatic shut-off feature that stops when the tank is full.

Do not “top off” the tank after the pump automatically shuts off. Overfilling can cause fuel to spill into the vapor recovery system, leading to damage or emissions issues.

Step 5: Replace the Cap and Close the Door

– Once fueling is complete, remove the nozzle and return it to the pump.
– Replace the fuel cap (or close the capless flap) securely. For vehicles with a cap, twist it clockwise until it clicks—this ensures a proper seal.
– Close the fuel door firmly.

Tip: If your Nissan SUV has a “Check Fuel Cap” warning light on the dashboard, it may be due to a loose or missing cap. Always double-check that it’s tight.

Step 6: Start the Engine and Check for Leaks

– Return to the driver’s seat and start the engine.
– Listen for any unusual sounds or smells.
– Visually inspect the fuel area for leaks—look for wet spots or gasoline odor.

If you notice any leaks, stop driving immediately and have the vehicle inspected by a professional.

Part 2: How to Replace the Fuel Filter in a Nissan SUV

While refueling is routine, replacing the fuel filter is a maintenance task that should be done periodically. A clogged fuel filter can cause poor acceleration, engine stalling, and reduced fuel efficiency.

Step 1: Determine If Your Fuel Filter Needs Replacement

Most Nissan SUVs have a fuel filter that should be replaced every 30,000 to 60,000 miles, depending on driving conditions. Signs that it may need replacement include:

– Engine hesitation or stalling
– Difficulty starting the vehicle
– Reduced fuel economy
– Check Engine Light (CEL) with codes related to fuel pressure

Consult your owner’s manual or a Nissan service guide for your specific model’s recommended interval.

Step 2: Gather the Necessary Tools and Supplies

Before starting, make sure you have:

– New fuel filter (compatible with your Nissan SUV model)
– Safety glasses and gloves
– Fire extinguisher (rated for flammable liquids)
– Wrench set or fuel line disconnect tools
– Drain pan or rags
– Jack and jack stands (if the filter is under the vehicle)
– Owner’s manual or repair guide

Work in a well-ventilated area, preferably outdoors or in a garage with the door open.

Step 3: Relieve Fuel System Pressure

Modern Nissan SUVs have high-pressure fuel systems. Before disconnecting any lines, you must relieve the pressure to prevent fuel spray.

– Turn off the engine and remove the key.
– Locate the fuel pump fuse or relay in the fuse box (usually under the hood or dashboard). Refer to your owner’s manual for the exact location.
– Start the engine and let it run until it stalls—this burns off the remaining fuel in the lines.
– Turn the ignition off and disconnect the negative battery terminal for extra safety.

Step 4: Locate the Fuel Filter

The fuel filter is typically located:

– Under the vehicle, along the fuel line between the fuel tank and engine
– Near the rear axle or under the driver’s side
– In some models, it may be inside the fuel tank (not serviceable by the owner)

Use a flashlight and mirror if needed to locate it. Refer to your repair manual for exact placement.

Step 5: Disconnect the Fuel Lines

– Place a drain pan beneath the filter to catch any spilled fuel.
– Use a fuel line disconnect tool or wrench to carefully disconnect the inlet and outlet lines.
– Some filters have quick-connect fittings—press the release tabs and pull the line off.
– Be prepared for a small amount of fuel to drip out.

Tip: Label the lines or take a photo before disconnecting to ensure correct reinstallation.

Step 6: Remove the Old Filter

– Loosen the mounting bracket or clamp holding the filter.
– Slide the old filter out.
– Inspect it for dirt, rust, or damage—this can indicate other fuel system issues.

Step 7: Install the New Fuel Filter

– Position the new filter in the same orientation as the old one (check the flow arrow on the filter).
– Secure it in the mounting bracket.
– Reconnect the fuel lines, ensuring they click into place or are tightened properly.

Double-check all connections before proceeding.

Step 8: Reconnect the Battery and Test

– Reconnect the negative battery terminal.
– Turn the ignition to “ON” (but don’t start the engine) for a few seconds to prime the fuel system.
– Repeat this 2–3 times to build pressure.
– Start the engine and let it idle for a few minutes.
– Check for leaks around the filter and connections.

If everything looks good, take the vehicle for a short test drive to ensure smooth operation.

Troubleshooting Common Issues

Even with careful steps, you might encounter problems. Here’s how to handle common issues:

Fuel Cap Warning Light Stays On

– Ensure the cap is tightened until it clicks 3–4 times.
– If the light persists, the cap may be damaged or the seal worn—replace it.
– In some cases, a faulty fuel tank pressure sensor could be the cause.

Engine Won’t Start After Filter Replacement

– Check that all fuel lines are properly connected.
– Verify the fuel pump fuse is intact.
– Prime the system by turning the key to “ON” multiple times before starting.

Fuel Smell or Leak

– Stop the engine immediately.
– Inspect all connections and the filter for loose fittings or cracks.
– Tighten or replace components as needed.
– Never drive with a fuel leak—it’s a serious fire hazard.

Poor Performance After Refueling

– Ensure you used the correct fuel type.
– Check for water contamination in the fuel (rare but possible).
– If symptoms persist, have the fuel system inspected for clogged injectors or a failing fuel pump.

Safety Tips When Working with Gasoline

Gasoline is highly flammable and should be handled with care. Follow these safety guidelines:

– Never smoke, use lighters, or create sparks near fuel.
– Avoid static electricity—touch a metal part of the vehicle before handling fuel.
– Wear safety glasses and gloves to protect your eyes and skin.
– Keep children and pets away from the work area.
– Dispose of old fuel and filters properly—take them to a hazardous waste facility.

When to Call a Professional

While refueling and basic filter replacement are DIY-friendly, some situations require a certified mechanic:

– If the fuel filter is inside the fuel tank (common in newer models)
– If you’re unsure about fuel line connections
– If the Check Engine Light remains on after service
– If you detect a strong fuel odor or suspect a leak

Nissan dealerships and certified repair shops have the tools and expertise to handle complex fuel system issues safely.
