On this blog, we’ve written extensively about the American-made Hyundai Tucson and its various features. Today we’re going to talk about what kind of fuel this SUV needs to run correctly. Let’s start with a quick answer to that question:
Hyundai Tucson’s manufactured between 2004 – 2020 use regular unleaded gasoline with an octane rating of 87 AKI (the USA and others) or 91 RON (Europe only). The 2021-Present-day Tucson uses premium unleaded gasoline with an octane rating of 91 AKI (the USA and others) or 95 RON (Europe only). Tucson’s that have a diesel engine use No. 2 Ultra Low Sulfur (climatized) diesel at temperatures above 23°F (-5°C) or No. 1 Ultra Low Sulfur diesel below 23°F (-5°C).
However, that doesn’t fully cover the topic. Below we’ll talk about the various kinds of fuels available on the market and whether or not they are compatible with the Hyundai Tucson. Furthermore, we’ll talk about the mileage of the Tucson, its tank size, and how much it costs to fill up the Tucson. Read on!
Gasoline Containing Alcohol Or Methanol
Hyundai Tucson’s manufactured between 2004 – 2018 can use 90% regular unleaded gasoline with a maximum of 10% ethanol. This means the use of E-15 gasoline is forbidden in these vehicles. Tucson’s manufactured from 2019 onwards can use fuel that has 15% ethanol, and E-15 is possible. No generations of the Tucson can use E-85 (85% ethanol) gasoline.
If you use fuel with an ethanol percentage higher than the guidelines we’ve given above, then it’s very likely that you will damage the fuel system and the engine of your Tucson. It’s good to know that this damage is not covered under the warranty of the car.
Furthermore, the use of gasoline that has methanol mixed into it is strictly forbidden in all Hyundai Tucson’s. Doing so will cause damage to the fuel system and engine that’s not covered under warranty.
Using Fuel Additives
Using fuel additives for the Hyundai Tucson (that are not detergents) is strictly advised against. These additives include, but are not limited to:
- Fuel additives with silicone
- Iron-based additives such as Ferrocene.
- Other metallic based additives. These will result in misfiring, stalling, damage to the catalyst and engine and poor accelaration which will severely decrease the lifespan of the fuel system.
All of these additives can result in the Malfunction Indicator Lamp illuminating on your dashboard.
Detergent Fuel Additives
The only exception in the ‘fuel additives’ category is the fact that some detergents are indeed allowed. Hyundai advises you to use TOP TIER gasoline in the Palisade. TOP TIER gasoline has added detergents that help prevent deposits in the fuel system. Information on where to find this fuel can be found on toptiergas.com.
If TOP TIER fuel is not available, customers are allowed to add one bottle of additive to the fuel tank according to the maintenance schedule of the Palisade. Looking at the maintenance schedule of the Palisade, we found that additives can therefore be added every 8.000 miles (13.000 kilometers) or every 12 months, whatever comes first.
Additives for the Hyundai Tucson can be bought at your Hyundai dealer, and Hyundai does not give any recommendations about this in the owner’s manual.
Gasoline Containing MTBE
Hyundai recommends avoiding fuels containing MTBE (Methyl Tertiary Butyl Ether) over 15.0% vol. (Oxygen Content 2.7% weight) in your vehicle.Fuel containing MTBE over 15.0% vol. (Oxygen Content 2.7% weight) may reduce vehicle performance and produce vapor lock or hard starting.
Gasoline Containing MMT
Some gasoline contains additives based on MMT (Methylcyclopentadienyl Manganese Tricarbonyl). Hyundai strongly advises against the use of MMT in the Palisade. This fuel can reduce performance and damage the emission control system. Furthermore, the malfunction indicator lamp will turn on.
Diesel that contains no more than 7% biodiesel (also referred to as B7 diesel) can be used in the vehicle if it meets EN14214 specifications (Europe) or ASTM D6751 (USA) specifications. Using biofuels exceeding 7% made from rapeseed methyl ester (RME), fatty acid methyl ester (FAME), vegetable oil methyl ester (VME), etc., or mixing diesel exceeding 7% with biodiesel will cause increased wear or damage to the engine and fuel system. This damage is not covered under warranty.
Fuel Mileage Of A Tucson
Let’s talk about the gas mileage of the Tucson. It will surprise a few people that most generations of the Tucson do not have that good of fuel mileage. The large SUV didn’t have any hybrid options for a long time and therefore solely relied on its gasoline in the tank. However, these days there are also hybrid options available that offer a good mileage. Have a look!
|Year||Engine||Combined MPG||City MPG||Highway MPG|
|2004 – 2009||2.0 2WD||22||20||25|
|2009 – 2013||2.0 2WD||25||22||29|
|2013 – 2015||2.0 2WD||25||23||28|
|2016 – 2018||1.6 Eco FWD||28||26||32|
|1.6 Eco AWD||27||25||30|
|2018 – 2021||2.0 FWD||26||23||30|
|2022 – Present-day||1.6 Hybrid||37||37||36|

Tank Size And Cost Of A Full Tank
The 2009 – 2015 Tucson has a tank size of 15.3 gallons (58 liters). The 2016 – 2018 Tucson has a tank size of 14.53 gallons (55 liters) or 16.38 gallons (62 liters). The 2018 – 2020 Tucson has a tank size of 16.38 gallons (62 liters), and the 2021 – Present-day Tucson has a tank size of 14.27 gallons (54 liters).
Using these numbers, we come to the following conclusion:
The 2009 – 2015 Tucson costs $51.68 for a full tank of gas. The 2016 – 2018 Tucson costs $49.08 or $55.33 for a full tank of gas. The 2018 – 2020 Tucson costs $55.33 for a full gas tank, and the 2021 – Present-day Tucson costs $48.20 to fill up the tank.
