Pulling up to the pump at gas stations forces you to choose between several fuel options. If you've never learned the difference between all octane ratings, it can be easy to select the wrong one for your vehicle's engine. Should you be considering a Genesis G70, you might be wondering if you should fill the tank with premium, or high octane, gasoline. We researched the Genesis G70 from multiple sources so that you will know for sure before you fill up the tank for the first time.

As the Genesis G70 is a high-performance vehicle, you should always fill up the tank with premium gasoline.

Now that we know that you should always use premium gasoline for your Genesis G70, we'll look at why this octane rating works best in this model vehicle. You might also be curious if the Genesis G70 car is expensive to maintain or how reliable it is. Is the Genesis G70 considered a sports car? How fast will a G70 run? For the answers to these and other questions, read ahead in this post to see what we found out during our research.

Why you Should use Premium Gas in the Genesis G70

When you see the word "premium" at the pump, it refers to the gasoline's octane rating. Regular gasoline has an octane rating of 87 to 90. Premium-level gasoline will have an octane rating of 91 and higher. 

The level of octane in the fuel will determine how much compression it has before it ignites. The higher the octane level, the more compression. But what does this mean for the Genesis G70?

This luxury sedan has a high-performance engine under the hood. When the fuel and air are sucked into the cylinders, the fuel is compressed and then ignited by a spark plug. This combustion forces the pistons to move, thus forcing the engine's parts to go into motion. Regular fuel will ignite beforehand and cause the engine to knock, creating some long-term damage.

What Happens if you Don't Use Premium Gas?

The impact of not using premium gasoline will depend upon the type of engine your vehicle has. No matter what you are driving, your owner's manual will indicate what fuel grade to use. Certain engines perform better with certain octane ratings, and failure to comply can have some lasting effects.

Should you be fueling a vehicle that has a high-performance engine, as most luxury vehicles and sports cars will have, you will more than likely require premium fuel. You need a higher compression of the fuel for these engines so that the fuel ignites in the cylinders at the proper moment.

As we mentioned earlier in this post, using a low octane fuel in a high-performance engine can cause lasting damage over time.

If you don't have a high-performance engine, your vehicle will perform fine with the lower octane fuel. You might want to use premium anyway since the industry does make it sound like this fuel grade is better for your engine.

However, adding premium fuel to a standard engine won't increase its performance in any way. Unless you have a high-performance engine or have a vehicle that specifies premium fuel, you're best just filling your tank with low octane gasoline.

Is Genesis G70 Reliable?

U.S. News rated the Genesis G70 an overall 8.4 out of 10, placing it among the top in its class of smaller luxury sedans. With a safety rating of 9.8/10 and a performance rating of 8.4/10, it's easy to see why it has been one of the industry's top choices in its class.

The overall reliability rating for the G70 is 84 out of 100. This places it near the top in this category as well. A powerful and long-lasting engine and premium parts make the G70 a safe bet for consumers who need a car that can rack up a lot of road miles.

The G70 was rated #3 out of 20 in smaller luxury cars, being barely outdone by the Audi A4 and the Audi A5. Good Housekeeping rated it as the "Best New Family Car of the Year" in 2020, and it was "Car of the Year" for Motortrend in 2019.

Are Genesis Cars Expensive to Maintain?

For a luxury vehicle, Genesis models are not as expensive to maintain as you might think. Motortrend reports that it will cost an estimated $6,354 in repairs and maintenance in the first five years. This is about average for vehicles in this class. 

As with most model Hyundais, an extensive and comprehensive warranty covers the G70. The G70 has a 5-year/60,000-mile basic warranty and a 10-year/100,000-mile powertrain warranty.

Of course, you'll want to be certain that you properly maintain the Genesis G70, and follow the factory recommended maintenance schedule that is in the owner's manual.

Warranties are usually void if you don't maintain the vehicle to the standards of the contract. For additional information on what maintenance you need and at what intervals, consult your G70's owner's manual.

Is the G70 a Sports Car?

Defining a sports car can be a little tricky, especially if you are relying on your insurance company for the definition. In general terms, a sports car is a two-door car with a low center of gravity. They often have a high-performance engine. Sometimes, an insurance company will rate any two-door car as a sports car, regardless of what it has under its hood.

The Genesis G70 is marketed by Hyundai as a Luxury Sports Sedan. The twin-turbo 3.3L engine runs at 365 horsepower, giving the driver a lot of momentum from this high-performance engine. The sleek exterior design lends itself to what you might imagine when someone mentions a sports car.

Other sports cars in this class of sedans include the Mercedes Benz C-Class, the Kia Stinger, and the BMW 3 series. Clearly, Hyundai has put itself up against some pretty stiff competition in retailing the G70. But the overall ratings from critics and the modest price tag are helping this vehicle get the recognition it deserves. 

How Fast is a Genesis G70?

The 3.3L twin-turbo engine that is available for the Genesis G70 will push most drivers to their limit. With this V-6 engine under its hood, the G70 can make it from zero to 60 miles per hour in 4.5 seconds. This speed puts it above average among the other 20 vehicles in the same class.

The standard high-performance engine that will be in many Genesis G70 models is still pretty fast. You can expect a G70 with the 2.0 L twin-turbo engine to accelerate from zero to 60 in 6.5 seconds. As with the 3.3L engine, the 2.0L is just a bit above the average when compared to smaller luxury sedans. 

When the G70 was tested for its quarter-mile run, it was able to finish in 13.3 seconds with the 3.3L engine and 14.7 seconds with the 2.0L. While there are faster models in this class, the G70 is still considered pretty swift.  

In Closing 

The Genesis G70 is a leader among smaller luxury sedans. This sports car will run best on high octane gasoline, so Hyundai recommends that you always fill the tank with premium graded fuel. The G70 is a swift and reliable vehicle and is highly rated among critics and consumers alike. The affordability and relatively low maintenance costs will surely help boost its popularity even further among those wishing to drive a sleek sedan. Drive safe!
