Audi is a popular car for several reasons. The German-made car not only offers enhanced performance in every model, but its AWD system is unmatched. However, taking these two highlights, does that mean the Audi cars and SUVs need to have premium gas to run at their best? We have researched to find the proper gas type for each Audi model.

Do Audi Cars Need Premium Gas? [Breakdown By Model]

Audi Models That Thrive On Premium Fuel

Audi vehicles all come equipped with what is called direct injection technology. This means that the gas and air mixture will be directly injected into the combustion chamber of each cylinder in the engine. This will help the motor burn much more efficiently, which is why premium fuel is necessary.

Audi vehicles are made to run on premium gasoline because of their direct-injection technology and turbocharged engines. Without using premium fuel, you can damage your Audi's engine and even cause severe damage if you don't fill up with regular gas when it's recommended.

Let's take a look at each Audi model that needs premium fuel and its features.

Is it OK to put regular gas in a premium car?

For a large majority of cars, you can get away with using regular gas. This may work just fine for your car, but it's still best to use what your vehicle was designed for. If you really want to use regular gas, that's your call. If you do happen to put regular gas in a premium car, then drive the car until empty, and then at the next fill up, put in premium gas!

What happens if I put regular gas in my Audi?

If you've accidentally put regular gas in your luxury Audi and have wondered what it did to the engine, we are here to tell you that it won't hurt your car!

As discussed above, run the Audi until the vehicle is completely out of gas and fill back up with premium gas. However, if it isn't a high-performance Audi, regular gas or premium gas is a complete preference.

Can I put 93 gas in my Audi?

You can put 93 Octane in your Audi if you want. It will work just as well and be more expensive than using premium-grade and regular-grade fuel.

However, keep in mind it isn't necessary to use 93 octane gas unless you have a high-performing Audi such as the R8. This is simply because the other Audi models don't need this type of high-grade fuel to perform at their best.

Do all luxury cars require premium gas?

The answer to this question is no. Luxury cars and high-performance vehicles are designed to run on premium fuel, but you can certainly use regular if you choose! Read what your owner manual says about which octane type is suggested for best results in your particular car.

Most of the time, especially with newer, more advanced engines, regular or premium fuel will not affect your performance. Of course, it's always best to follow the manufacturer's manual, but for most cars, it is safe to use either.

Can I use regular gas in a BMW?

It is best to use premium gas for most BMWs, but it isn't essential to the vehicle. However, you usually get better performance if you stick with premium fuel.  If you have a BMW that requires premium gas, then do not put regular in the tank.

For most BMW's this is easy to remember because those models usually say right on the trunk or fill-up door what octane level of fuel to use. This octane number relates directly to your engine type and is listed on your owner's manual. In some cases, the fuel type is even printed directly on the vehicle itself. Audi has similar labeling for their premium fuel recommendations.

Does premium gas really make a difference?

The short answer is yes; it does make a difference. Whether you think it does or not, the EPA recommends that drivers use premium-grade fuel because of its increased octane rating. The higher the octane rating, the better fuel burn and combustion efficiency are in your car.

Yes, you will spend more money on premium gas. However, you will save a ton in the long run because your fuel efficiency and overall performance will improve your car, helping the engine run healthier.
