All Audi automobiles include a feature known as direct injection technology. This means that each cylinder’s combustion chamber will receive a direct injection of the gas and air mixture. The need for premium fuel stems from the fact that this will make the motor burn much more effectively.
Because of their turbocharged engines and direct injection technology, Audi automobiles are designed to run on premium fuel. If you don’t fill up with premium fuel when it’s advised, you could seriously harm the engine of your Audi.

What happens if you fuel a high-end Audi with normal fuel?
Does it really matter if I use premium fuel? Could your engine be harmed or lose its warranty if you don’t use premium fuel? The solutions might surprise you. Before your next trip to the gas station, continue reading to learn the truth.
What If the Manufacturer Requires It?
When a vehicle manufacturer specifies premium fuel, it’s because the fuel system of that specific vehicle is built to function best with higher octane fuel. In an engine that needs premium fuel, using normal petrol could violate your warranty. That is most likely to occur if repeated use results in severe engine knocking or pinging (premature fuel ignition, also known as detonation), which harms the pistons or other engine components. Other issues, such as worsened engine performance and poorer fuel economy, may result from using the incorrect gasoline.
As an illustration, the following is what GM states about the matter in the owner’s guide for a car that needs premium:
91 or higher posted octane premium unleaded gasoline should be used. If the octane level is below 91, you risk damaging the engine and voiding the warranty on your car. When using gasoline with an octane rating of 91 or above, the engine requires maintenance if loud banging is observed.
Keep in mind that this only applies to engines that demand premium gas. Although some manufacturers advise using premium gas, you can also use standard or mid-grade gas. Usually, they mention that using gas with a lower octane rating could affect performance and fuel efficiency. They advise using premium when that starts to become noticeable, or if engine knock starts to happen.
Differences Between Premium and Regular Gas
Similar to ordinary unleaded fuel is premium gas. Both are highly flammable and made from crude oil. But one of the biggest variations is that premium fuel has a higher octane rating. The majority of premium fuel has an octane rating of 90 or above. When it comes to supplying automobiles with power while avoiding knocking, octane is crucial. Pre-ignition, an explosion that results from gasoline and air igniting before they should, produces a knocking sound. The term “octane” describes how effectively a fuel can withstand pre-ignition. Premium gasoline is less likely to pre-ignite or knock when it has an octane rating of 90 or higher. Additionally, premium fuel has additives and detergents that make engines run cleaner. Less pollution is produced as a result of the additives and detergents.
The Bottom Line
Modern engines’ computers can, up to a degree, modify the ignition system to work with lower-octane fuel. Fuel efficiency and acceleration are likely to suffer at least significantly when using normal gas. Regular is more likely to detonate because it has a lower octane rating. Long-term or under extreme loads, burning regular in an engine made for premium can induce engine knock, which can harm the pistons, valves, or spark plugs. You might not hear knocking because of the knock sensors and the capacity of the automobile to delay the spark timing, but that doesn’t mean premium isn’t necessary.
In most premium-designed automobiles, regular can be utilized at least occasionally without consequences, but it’s not a good idea to do it frequently. In conclusion, see the owner’s manual. You should take the engine manufacturer’s word for it if they say premium is needed. Don’t try to buy normal gasoline to save a few cents per gallon. This could result in future costs that are significantly higher.
Can 87 gasoline be used in an Audi?
Peter inquired about the 2013 Audi S4 3.0T quattro Premium Plus Sedan AWD on May 24, 2013 at 9:24 AM.
Audi “recommends” 91 octane gas but “needs” 87 octane at the very least. Will regularly using 87 octane damage my car? According to what I understand, modern high-tech cars are built to automatically correct for lower octane unleaded gas in order to prevent “knocking” or “pinging.” Do you really need to pay more for “premium” octane gas?
What happens if standard gas is unintentionally used in place of premium gas?
The Drive reported that if you accidentally fill up with ordinary petrol, your car’s ECU will change engine timing and performance to accommodate the lower-octane fuel.
When there aren’t any premium pumps nearby, this is typically acceptable, but using the cheapest fuel for prolonged periods of time is not recommended.
Which model of Audi uses ordinary gas?
TT Audi. Similar to the A3 above, this attractive coupe/roadster combination is EPA-rated to operate on regular gas, but the 2.0-liter turbocharged engine in the Audi TT performs best when the tank is filled with premium.
Is premium fuel truly required?
There is no benefit to utilizing premium if your car does not ping when using ordinary. Your engine works absolutely fine with the current anti-knock level. Additionally, to compensate for varying octane levels and prevent pinging or knocking, modern complex engine controls modify the engine’s timing and fuel mixture. Many automobiles simply need normal petrol.
What occurs when 87 is put in an Audi?
Most of us regularly operate a car or truck that runs on ordinary, unleaded fuel. This makes filling up at the gas station rather straightforward. But occasionally, someone can unintentionally use a different type of gasoline than usual to fill their car.
The majority of today’s cars and trucks are equipped with electronic fuel management systems that can detect the difference between ordinary and premium gas (lower and higher octane) and modify the ignition timing and fuel injection accordingly.
Don’t worry if you mistakenly put a higher octane blend (such 91, 92, or 93) into your tank than the standard 87-octane fuel. Actually, you’re using a different gas blend to fill your car or truck, which means your engine will operate differently as a result. There might be a slight difference in how the car feels and you might see better gas mileage, but that’s about it.
Premium Gas Vehicles
Do not become alarmed if the manufacturer of your automobile or truck suggests premium fuel for your vehicle but you instead use normal. Even though premium is advised, you are not required to use it; the engine can run just as well on standard gas.
You can run into issues if you use standard fuel when your manufacturer calls for premium. How well your car or truck will handle normal petrol depends on the sophistication of your fuel system as well as other elements like how your engine is tuned, what the timing is, and how hot it runs. Most of the time, the car will run just fine, although you might notice less power and reduced gas mileage. Because the fuel isn’t burning properly in more acute cases, you might hear engine banging or valve chatter. You should take it to your mechanic because these things might harm your engine.
Diesel Vehicles
You must be aware of how diesel fuel and unleaded fuel differ from one another and which your car needs.
Inadvertently using unleaded fuel in a diesel-only vehicle will actually reduce the lubrication that diesel provides for the car’s components. As a result, there will be significant damage from the pieces grating against one another.
The damage may not be as severe if you fill your ordinary gas vehicle with diesel, but you won’t travel more than a few miles before the engine starts to splutter, cough, and lose power. You’ll be able to drive the vehicle once more when you replenish the diesel tank and flush out the fuel lines.
Do yourself a favor and refrain from starting your automobile if you have the wrong kind of gas in it and haven’t done so yet. When the incorrect fuel is pulled up into the fuel lines, engine damage results. Call a mechanic instead, and ask them to fix the problem.
Can my Audi A4 operate on 87?
It will function, but your engine could be harmed. Due to the turbo’s low compression ratio, 87 octane will not burn as well in the engine.
