Summary of Contents
Although a BMW X3 may run on ordinary petrol, the engine was built to operate on 91+ octane fuel. Using less-than-premium fuel to fill a BMW X3 could raise the chance of engine damage, such as pinging, which would reduce vehicle longevity. The lifespan of the car will be extended by using premium fuel.
What kind of harm can ordinary petrol actually do? Find out here how regular fueling your BMW X3 will affect it.
The Drawbacks of Filling Your BMW With Regular Gas
Buying expensive gas for your BMW or any other vehicle might be costly. You may be able to save money by using ordinary fuel depending on the model of your BMW, but there will be a cost. We think that saving money right away isn’t worth endangering your car.
Thanks to more electronic components, most new BMWs can run on ordinary gasoline, but this might put stress on several elements, including the electronic knock sensors in your engine. These electrical parts provide the engine the ability to recognize the sort of fuel it’s using and alter performance accordingly, protecting your engine.
Regular fuel has the additional drawback of altering the performance of your engine, which results in a reduction in power and slower acceleration. But this isn’t a significant loss. Most vehicles that are advised to use premium fuel but switch to normal gas will lose around 10 HP. This is something to keep in mind, especially if you bought your BMW for its power, even if it probably won’t be a major concern if you only use it to get around town.
There are some exceptions to this rule, just like with anything. Certain BMWs do need premium fuel.
These are the most typical causes for a BMW to need premium, but this is by no means a complete list. In the event that your BMW fits one of the following descriptions, avoid using normal gasoline in it:
- Your vehicle predates the 1996 model year.
- It’s a model M.
- It has a turbo engine or one with high compression.
- Your model of vehicle must utilize premium gasoline, per BMW (they recommend that all of their cars use premium, but only require it on select models)
A complete list of BMWs (model years 2012–2019) that demand premium can be found here, while a list of BMWs that recommend premium but can operate on regular can be found here. Remember, though, that continuing to run as usual can have negative effects. Above all, before converting from premium to normal unleaded, always consult your owner’s manual.
modified gasoline
Reformulated gasoline burns more efficiently and sustainably than regular gasoline. The RFG has less hazardous chemicals and is intended to lessen smog production. RFG is mostly utilized in places with poor air quality.
Only high-octane fuels are advised for BMW vehicles. Although drivers are free to use RFG, there is a chance that doing so will sometimes void the warranty. The best course of action is to adhere to BMW’s recommendations for its automobiles.
Which BMW models need premium fuel?
Premium gasoline is required for all BMW M vehicles and all BMW models produced prior to 1997. Only 91+ octane gasoline should also be used in high-compression engines.
BMW M automobiles are always equipped with powerful engines that have to make use of the best fuels, lubricants, and other consumables in order to operate at their peak efficiency and avoid long-term damage.
It should go without saying that these vehicles should only ever be powered by the best fuel available.
You should always use premium fuel in older BMWs and vehicles with high-compression engines, such as turbocharged versions. Premium fuel is required in these circumstances, according to BMW.
Premium gas is just advised, not required, for any other BMW models. But we would continue to use premium.
Even though gas prices are higher, we find solace in the fact that we are taking every precaution to safeguard our engines in the long run.
If you own a BMW and are unsure of the recommended fuel to use, see your owner’s manual or the sticker located under the fuel filler cap. There won’t be any problems as long as you follow BMW’s advice.
What happens if I don’t fill up my BMW with premium fuel?
While my Toyota is in the repair for the next several days, I’m borrowing my brother’s BMW, and I unintentionally put ordinary gas in the vehicle. I assumed BMWs used some kind of premium fuel. What occurs if ordinary gas is accidently poured into a BMW?
In less than two minutes, find out if your auto insurance is being overcharged.
The quick response is nothing. You won’t run the risk of damaging your brother’s automobile because the majority of BMWs can run on ordinary gas.
When you fill up a BMW with standard gas instead of premium, the car will detect this and may operate with a little less power and timing, but all of its components will function as intended. BMWs are equipped with sensors that can identify the type of fuel being used and will adjust the engine accordingly.
If you still feel guilty about filling up your brother’s BMW with ordinary gas, make up for it by showing him the Jerry app and assisting him in saving hundreds of dollars on his auto insurance.
After you download Jerry, all you have to do is respond to a few questions that will take you around 45 seconds to do, and you’ll get car insurance rates for coverage that is identical to your current plan right away. Customers of Jerry save $887 year on average.
What type of fuel does a BMW X3 use?
What type of fuel does a BMW require then? As we previously stated, premium gas is ideal for a BMW. Because premium gasoline has a higher octane rating and is better suited to high compression engines, it is the optimum fuel for BMW vehicles. Regular gas only has an octane rating of 87, but premium gas might have a rating of 92.
Is premium really necessary for BMW?
No matter what model you have, BMW advises only using premium unleaded fuel. That’s not to say that your BMW won’t run on inferior fuel, but premium unleaded fuel will keep its quality over time, allowing you to constantly drive at peak performance.
Can I fill up my BMW X5 with normal gas?
Is premium fuel required for the BMW X5? BMW formally advises 93-octane fuel for the X5 to achieve the highest performance possible. However, using standard unleaded fuel is not hazardous.
Will 89 octane gas work in a BMW x3?
The minimum is 89, and 91 is advised. My Stinger manual also states the same thing. I enjoy having 91 for increased performance when I want it and 89 for strong but not maximum performance.
Can a BMW run on ordinary gas?
BMW, for instance, advises using premium fuel in all of the vehicles it sells in the United States, though they can also run on ordinary. According to Thomas Plucinsky, a BMW representative, using lower-octane fuel normally doesn’t hurt the engine.
Do I actually require premium fuel?
Some high performance and luxury cars need premium gas, which is defined as gas with an octane level of 91 or higher. High octane gasoline has a harder time igniting, which helps high performance engines avoid pre-ignition and knocking. If you frequently fill up with ordinary when your vehicle needs premium fuel, the engine could become damaged.
Do all high-end SUVs need premium fuel?
There is a widespread myth that you must only use premium gas when driving a luxury car. Due to this misunderstanding, many owners of luxury vehicles will purchase premium gas even if their car doesn’t need it.
There is a widespread myth that you must only use premium gas when driving a luxury car. Due to this misunderstanding, many owners of luxury vehicles will purchase premium gas even if their car doesn’t need it. The truth is that most premium automobiles run on normal petrol, if not all of them. If your car doesn’t require premium fuel to function properly, adding the expenditure will be pointless and you’ll end up wasting money.
This does not imply that all luxury vehicles can run on premium fuel. High-compression engines are a common feature of high-performance automobiles, and since normal gas can become unstable under pressure and high heat, it may catch fire. This will produce an audible sound known as “pinging,” which is typically used to describe it. Repeated use could eventually harm the engine permanently.
Is Costco fuel suitable for BMW?
In all of our BMWs and other vehicles, we utilize Costco gas. Even my BMW m8 v8 with dual turbos uses it. It’s ideal and effective. Kirkland Signature gasoline satisfies all Top Tier standards for Regular, Premium, and Diesel.
Which octane does BMW advise using?
It seems terrible to even consider using normal unleaded in this $129,595 intercontinental ballistic missile. Although that appeared unlikely in such low temps, using the cheap stuff would have been totally out of character with what an owner would do. BMW expressly forewarns about engine harm from doing so (at least until this M5 reaches its fourth owner sometime in 2036). In order to comply with BMW’s requirement for 91-octane fuel, with 93 being suggested, we switched between the popular types of premium petrol based on the state you’re in. Are Californians leaving money on the table with their diluted premium? We were curious.
The dyno findings were unexpected. No, not because 91 and 93 octane have 13 fewer horsepower. No, the delta was within the expected range. Just how much power and torque we measured left our jaws hanging. The uber 5-series is incredibly undervalued on either fuel. While BMW claims 617 horsepower at the crank, the dyno shows that it produces that amount at the wheels on 93-octane premium fuel (after driveline losses). Furthermore, both fuels provided a lot more torque than the 553 lb-ft of claimed torque from BMW.
The acceleration times of the M5 were all reduced by a single tenth of a second thanks to the higher-octane fuel. This propels the five-seat, 4246-pound four-door into the realm of supercars with a time-bending 2.7-second slingshot to 60 mph and 10.8 seconds through the quarter-mile. Although the BMW claimed to have the highest fuel efficiency margin in the test, the lower octane was preferred due to a 0.7 mpg differential. The M5 Competition is evidence that the octane rating does matter, but with these two premium fuels, using 91 octane won’t leave you significantly worse off.
What occurs if normal fuel is used in a high-end vehicle?
Engine knock is reduced by using premium gas, which has a higher octane rating. According to The Drive, 87 octane will almost immediately start the engine banging in older vehicles that need premium fuel. However, newer models of vehicles are more prepared to manage it.
What benefits and drawbacks come with owning a BMW?
- Engine and transmission quality (Pro)
- interior design caliber (Pro)
- Foreign Automobile Manufacturer (Con)
- Less annual depreciation (Pro)
- High Costs of Ownership (Con)

What happens if 89 gasoline is placed in a 91 vehicle?
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:
“Use 91 octane or higher premium unleaded fuel that has been posted on the label. 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.
