The most noticeable difference between premium and regular fuel, according to data from True Car, is fuel economy. However, standard gasoline has an octane rating of 87, while premium gasoline has a higher rating between 91 and 93.
In general, normal gasoline is safe to use in the majority of current automobiles. Many older Audi vehicles will function just as well on ordinary fuel as they will on premium, unless your specific model calls for premium.
Audi, for example, contributed to the development of the Top Tier Gasoline standard for premium fuels, which calls for a greater proportion of additional detergents than the EPA mandates. According to the argument, a lower additive concentration results in more debris deposits on engine parts like the fuel injector and intake valves, which decreases engine efficiency and raises emissions.

What happens if I fill up my Audi with ordinary gas?
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.
Do expensive automobiles actually require premium fuel?
It would be easier to get your foreign luxury car serviced and repaired if you are aware of the type of gas it requires before you buy it. Luxury automobiles are enticing purchases, but you must first decide if you can afford one by analyzing the ownership costs. The most common expense associated with owning a car is fuel, therefore choosing the right sort of petrol for your vehicle is crucial. Could you buy cheaper petrol if you have a premium car if you need to cut costs? Do luxury vehicles need premium fuel? Let’s talk about:
Lead was originally utilized to make gasoline, but once the health risks of lead were discovered, it was no longer used, according to Kelley Blue Book. As a result, contemporary gas is always leaded-free.
The octane level is what makes the difference. Regular gas has the lowest octane content, followed by mid-grade and premium. Premium gas has the highest octane content. The amount of octane in the gas affects how the gas is burned when the engine is running.
The many sorts of engines, including low- and high-performance engines, resulted in the creation of numerous forms of gas. Your car uses air and gas to ignite tiny explosions in the cylinders of the engine to start it. These explosions are influenced by the amount of octane in the gas and how well the engine is performing.
In comparison to conventional gas, premium gas’s higher octane level takes longer to ignite the explosions in the car’s cylinders. Because their higher performance engines require more octane, luxury cars need premium petrol.
Your car’s gas cap will tell you what kind of fuel it uses. The owner’s manual for your car may potentially contain this data. If you don’t have an owner’s manual for your car, see if there is a digital version you can download from the manufacturer’s website, or get further information by contacting the service department of a dealership that sells your brand of vehicle.
Your car will operate just fine on regular petrol if it has a standard engine, like a Toyota Camry.
A performance-oriented engine, such as those found in the Volkswagen GTI or Dodge Challenger, or a luxury vehicle, such as a BMW or Mercedes, require premium fuel to function at their peak.
Check to verify if your vehicle needs to use premium gas or if Edmunds has created lists for your reference. You’ll notice that the majority of Luxury Cars on this list demand premium fuel.
In most circumstances, an expensive or high-performance vehicle’s engine will deteriorate from use of normal fuel.
Some claim that even though the manufacturer specifies that the car should run on premium gas, modern cars have the technology to modify the engine’s performance to run well on either type of gas.
However, logic implies that the engine will need to work harder to make up for that departure if it is required to operate differently than how it was initially intended to over the long run. According to Auto Trader, because of the modifications required to run on standard gas, the majority of vehicles that require premium gas will exhibit a knocking or pinging noise in the engine.
Older automobile models, according to Edmunds, must use the gas type advised by the manufacturer because knocking brought on by correcting for the lower amount of octane would have a greater impact on their engines.
For their vehicles to last for many years, proper maintenance is necessary. A automobile will need more maintenance as it is driven farther and with a harder-working engine.
Therefore, you might anticipate spending more on maintenance and repairs than you would by switching to regular fuel instead of premium fuel.
If you want to save money, can you choose between ordinary and premium? What would occur in the case?
If you’re thinking about switching between ordinary and premium, try it out first and record your findings. As the tank will initially be combined with both ordinary and premium fuel, the results of your study will be impacted. Therefore, make sure you drive your car on each for at least two refills.
If you love cars, you probably drive a vehicle with a powerful engine. When your car is using ordinary fuel, you’ll probably notice a loss of power when you speed. People who don’t drive quickly might not notice this difference, though.
When using standard fuel instead than premium, another change you might observe is a drop in fuel efficiency. According to CNN, cars made for premium gas typically have a 2.7 percent improvement in fuel efficiency when they only use premium petrol.
If you choose to switch between regular and premium fuel, think about the environmental effects. Engines may produce fewer emissions and exhaust when using premium fuel.
As an alternative, you might make a compromise and use mid-grade gas to save some money while minimizing the amount of work your engine has to do to make up for running on lower octane levels.
However, there will be instances when only premium gas should be used in your vehicle. If a luxury car will be working harder than usual, such as pulling a trailer or traveling long distances, premium gas is required. Keep premium in the tank for one filling prior to your car performing the heavy-duty task if you’re going on a road trip or towing a horse trailer, and only add premium when the engine is working extra hard. CNN claims that when engines are working harder, they are more likely to sustain harm from ordinary gas.
The manufacturer’s warranty may be voided if you use standard gas in a vehicle that was designed to run on premium fuel, so be sure to thoroughly check it.
Diesel fuel costs fluctuate a lot, so you might be skeptical if your car could operate on it when you see the lower price per gallon for diesel.
The answer is definitely no if the gas engine of your luxury vehicle is running. Gas and diesel engines operate differently; if you put gas or diesel fuel in one of them, the engine will be severely damaged. Inappropriate fuel use will require expensive repairs.
Do not start your car if you accidently put gas or diesel in your gas or diesel engine. If you start the automobile, the damage will already be done; the engine will run on the wrong gasoline, necessitating repairs. To have the improper fuel removed from your automobile’s engine, you will need to make arrangements for the car to be towed to a reliable repair.
To operate with greater fuel efficiency and to maximize their speed and performance, luxury cars need premium petrol. Even while you may use normal gas in a luxury automobile, doing so frequently will increase engine wear and could violate your warranty. To prolong the life of your engine and improve the performance of your vehicle, you should always choose the type of gas that the manufacturer of the vehicle has advised.
Can I fuel my Audi with 89?
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?

Do Audis frequently experience issues?
Everyone is aware that effective marketing can enable someone to sell sand in the Sahara. In order to obtain useful insight into the attitudes and trends in the automotive sector, Warrantywise, the top-rated provider of vehicle warranties in the UK, conducts a thorough amount of research and polls.
Warrantywise polled 750 British drivers to find out which automakers they considered to be the most dependable, and Audi made it into the top 10. Audi actually placed 28th out of 36 brands on their “Dependability Rating” scale for reliability in 2019. Based on the quantity of reported problems and breakdowns, they determined the rating.
Website for auto repair estimates RepairPal determines each brand’s overall score by calculating the frequency and cost of all repairs, including parts and labor. Audi received an average rating of 3.0 out of 5.0 at the time of writing. However, out of 32 car brands, that places the firm in 28th place.
Audi Q5 dependability
The Audi Q5 has a 3.0 out of 5.0 reliability rating, which places it 11th out of 14 luxury midsize SUVs. It has poor ownership costs because the average yearly repair cost is $928. Although repairs happen frequently, significant problems are rare, so you might make a few more trips to your shop for minor problems.
Cost
In comparison to the $807 average cost of premium midsize SUVs and the $652 average cost of all vehicle types, the total yearly cost of repairs and maintenance for an Audi Q5 is $928.
the typical annual sum for unplanned maintenance and repairs for all model years of a car. A vehicle’s greater average cost alone does not imply that it is less dependable. For instance, your car’s parts and labor may be pricey, especially if it’s a European luxury model, but if there are few serious problems and frequent service visits on average each year, that’s a sign of a dependable vehicle.
The typical annual frequency at which a vehicle is taken in for unplanned maintenance and repairs. This metric is produced by monitoring millions of distinctive automobiles over a number of years to ascertain the typical yearly visits for each make and model. Controls were included to prevent small, routine shop visits, such those for oil changes.
The severity element of dependability calculates the likelihood that a repair will cause a significant problem. The cost of a repair is assessed to be excessively expensive given the unscheduled nature of the repair if it is three times the average annual repair cost for all models. Due to their more expensive labor and component expenses, premium and luxury brands have a higher barrier.
Frequency
Owners of Audi Q5s need to take their cars in for unplanned repairs on average 1.2 times a year, as opposed to 0.6 times on average for premium midsize SUVs and 0.4 times on average for all vehicle models.
