How To Open The Gas Tank On A Hyundai Tucson

There are different types of fuel tanks on the market. For example, you can find fuel tanks that you can open with the push of a button or pull of a lever. Others require you to push the gas tank lid itself to get inside.

The fuel tank is located on the driver's side for the Hyundai Tucson. As a result, you will need to open the gas cap first to access the tank. To do this, you will need to lift the lever behind the driver's side floor mat. Then, you will need to remove the gas cap to access the gas tank.

The reason for these types of gas tank lids is to refrain from someone being able to open your gas tank. While it is isn't common, there are circumstances where siphoning your gas can happen.

Furthermore, this type of fuel tank avoids the risk of forgetting to put the gas cap back on and potentially losing it.

Why Isn't My Gas Tank Opening?

There are various reasons as to why your gas tank isn't opening. Let's take a look at them below:

Broken Fuel Door Release Lever

The first possible reason your gas tank isn't opening is that the fuel door release lever is broken. In this case, you will need to have it replaced to access your gas tank.

Stuck Fuel Hinge

The most common culprit for a stuck gas tank hinge is debris that has gotten into the latch. You will need to disassemble the faulty gas door latch and clean it out to remove any debris.

Stiff/Loose Pin And Bushings

Another reason you can't access your gas tank is because the pin and bushings are stiff or loose.

The best way to fix this is by removing the faulty latch, removing the pin and bushings, and then replacing them.

If these steps don't solve your problem, you will need to replace your entire fuel door release lever.

Rust Build-Up

Rust build-up may also be causing your car's gas tank to remain shut.

It may be a good idea to sand down the latch and apply Bondo spot putty to fix this. Once dry, you will need to prime and paint both the latch and pins to function correctly.

Faulty Spring

If you've replaced all of the broken parts to access your gas tank, but it still doesn't open, then there might be a faulty spring in the fuel door release lever. In this case, you will need to have it replaced.

How Do You Manually Open The Gas Door?

Hand open the car's oil cap to refuel.

In the case of a stuck gas tank lid, you will need to open it manually. First, don't try to pry the gas tank lid open, as this will damage the hinges. In addition, you should never stick a screwdriver down into the gas tank as it can puncture your fuel tank and cause a fire hazard.

Instead, you will need to access the emergency gas tank release. This emergency release will be located on the trunk and is typically a bright-colored lever or button. When you press this button or pull the lever, it will release the latch and allow you to access your gas tank.

What Kind Of Gas Does The Hyundai Tucson Use?

The Hyundai Tucson generally uses regular unleaded 87 octane gas or higher. However, if you own a turbocharged Hyundai Tucson, you may see better performance when using 91 octane options (premium gas).

Turbocharged engines can achieve better performance when using premium fuel because they have a higher octane rating. The higher octane rating helps prevent "knocking" or "pinging" noises that can occur when the air-fuel mixture in the engine is too lean.

Knock and pinging noises occur when the engine is under a high amount of stress and will produce these noises in an attempt to prevent itself from overheating.

If you own a turbocharged Hyundai Tucson, it may be beneficial for you to invest in premium gas so that your vehicle can run better and perform longer without heating up.

If you want to save money on gas, then it is suggested that you use regular unleaded gas and see how your car performs with this type of gasoline.

Can Hyundai Tucson Use Leaded Gas?

Unfortunately, the short answer is no. You should never fill your wheels up with leaded gasoline because it will corrode the valves and cause them to stick. This will result in an engine that uses more fuel than usual and can even damage the pistons within the engine.

Always use unleaded gasoline in your Hyundai Tucson so that you can have a smooth-running engine.

Can Hyundai Tucson Use Ethanol Gas?

The answer to this question is yes. The Hyundai Tucson fuel tank can accept ethanol, also known as E85.

This means that it will blend gasoline with up to 85 percent ethanol and 15 percent gasoline, depending on the season and availability of the E85 gas station.

However, the Hyundai Tucson can use E10, a blend of 10% ethanol and 90% gasoline.

How Much Does It Cost To Fill Up A Hyundai Tucson?

On average, the Hyundai Tucson costs $57 to fill. Of course, this will depend on the region you live in, though. For example, the average cost of a Hyundai Tucson gas tank fill-up in California could be more expensive than in Montana.

In addition, the cost of gas fluctuates every year. For example, the price of crude oil could be $80 a barrel one year and drop the following year significantly. This means that the cost of gasoline would also decrease at the pumps.

What If I Fill My Hyundai Tucson With Diesel?

Diesel is a type of fuel that you should never use in your Hyundai Tucson because it will cause damage to the engine and could even break down the seals. If you accidentally put diesel in your Hyundai Tucson, you will need to tow the vehicle to a mechanic shop.

Most diesel engines require more pressure than gas engines, so putting diesel in your Hyundai Tucson engine could cause it to overheat and break down.

Why Won't Diesel Work In A Hyundai Tucson?

Diesel will not work in Hyundai Tucson because they operate on different fuel types.

Diesel engines run on compression, which means they have to be surrounded by pistons instead of spark plugs like gas engines.

Unfortunately, the compression ratio in the engine is usually higher than gasoline engines, so it can still cause damage if you accidentally mix the two fuels.

Will I Get Better Gas Mileage On Premium Gas?

Generally, premium gas will give you better mileage if your car requires it. But, for example, the Hyundai Tucson can run on regular unleaded or premium gas, so it isn't clear if you will get better gas mileage by choosing premium fuel.

It is worth experimenting on to find out for yourself. To do this, you will have to fill up your tank with premium gas and see how much you can drive before refueling. Then, do the same experiment with regular unleaded fuel and compare your results.

From this experiment, you will get a good idea of whether or not premium gas is beneficial for your vehicle or if you should stick with regular unleaded.

To Conclude

You should always check the owner's manual to determine which fuel is right for your engine and what octane rating you need to put in it.

In addition, if you have issues opening the gas tank, then first access the emergency gas tank release. Then, after filling, take your Tucson to a Hyundai dealer to address the issue.
