An Owner’s Guide to Regular Gas and BMWs
It is a nice experience to drive a BMW, therefore you want to take good care of it. Everything from the additional time required to wash it correctly to the gas type used in the high-performance engine.
What if you are unable to fill your BMW’s tank with premium fuel? Despite the fact that it can seem like a bad idea to use ordinary gas in your BMW, it is still possible.
A BMW’s engine is capable of self-adjusting so that conventional gas can be used in it without causing damage. This implies that you may fill up your tank with any sort of gas you like without worrying about how it will effect your engine.
However, there may be more factors at play than you might realize when choosing between normal and premium gas. We’ll go through all the information so you can choose the sort of gas you want to utilize with confidence.
What occurs if standard gas is used in a BMW?
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 occurs if premium gas is not used in a BMW?
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.
Can I fuel my BMW with 89 octane?
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 happens if I accidently fill up my car with ordinary gas?
Your car’s ECU will change engine timing and performance to fit with the lower-octane fuel if you accidently fill up with ordinary fuel, according to The Drive. “In most cases, this is OK for situations when there are no nearby premium gasoline pumps, but using the cheapest fuel for extended periods of time is not recommended.”
Will premium gasoline damage a car?
There is a reason why the owner’s manual for your car advises using premium gas. High-compression engines, turbochargers, and other high-performance features are common in vehicles that use premium fuel. While not using premium gas won’t necessarily harm your engine, using standard or midgrade gas could reduce some of the performance of the premium engine you purchased.
Can BMWs use 87 octane fuel?
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.
Why does a BMW need premium fuel?
91+ octane fuel is the fuel created exclusively for use in BMW high-compression engines. Because it optimizes engine function and reduces fuel waste, you can travel farther on a single tank of gas, increasing your miles per gallon.
What occurs if I fill up with normal gas once instead of premium?
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.
Imagine putting 87 in a BMW.
The STP octane booster, on the other hand, is of no use at all. It won’t hurt it, the car will compensate and just run with less timing and produce less power, but there won’t be any long-term damage.
Do I actually require premium fuel?
Burning premium gas is not necessary for the majority of people, although it is advised. Your automobile manufacturer suggests premium for a reason, and it’s not because they are working closely with the oil industry. The plain truth is that premium fuel is required for your car to operate at its best efficiency, according to tests.
What happens if you fill a 93 gas tank with 87?
Therefore, I might have committed a mistake that could be damaging. I typically fill up my automobile with “normal gas” or gas marked “87.” But just now, I accidentally topped off my half-full tank with some premium gas with the designation “93.” Do I need to worry? What happens when you combine two distinct fuel types?
When it comes to this kind of thing, it’s always better to be cautious than sorry. The answer is that not much happens when you combine 87 and 93 gas.
Regular, midgrade, and premium gas grades are terms used to describe the octane content of the fuel. Additionally, that is what those numbers 87 and 93 are indicating. Gas with an octane rating of 91 or higher is classified as premium gas, whereas gas with an octane rating of 89 or 90 is classified as midgrade gas.
Higher octane gas is generally better for your engine and will produce marginally better performance. On the other hand, you obtain their average when you combine two distinct octane levels.
You therefore have a full tank of 90-octane gas if you have exactly half a tank of 87-octane gas and half a tank of 93-octane gas.
It will never be an issue to add higher octane gas to an engine made to use lower octane gas. However, if you put regular petrol in an engine that needs premium, you’ll all have performance issues.

Can you use regular gas again after using premium?
I really can’t keep up with how costly gas is getting! My car needs premium gas, but the cost is just prohibitive. Can I convert from premium to ordinary gas without any problems?
In a nutshell, yes, you can typically temporarily switch from premium to normal gas**. However, if your car needs premium fuel, your engine can begin to operate poorly.
It’s difficult to comprehend why some cars require either premium or ordinary gas when so many people are unsure of the differences between the two. But the quantity of octane in it makes a significant distinction between premium and normal gas.
High octane levels in premium gas enable it to tolerate high temperatures without igniting. Normal gas, however, can burn at considerably lower temperatures. Therefore, when premium gas ignites, more power is released. Although most automobiles won’t notice a difference, high-performance engines are frequently made to consume premium fuel.
However, a high-end engine will not operate as effectively with standard gas as it will with premium gas. But be cautious—if you do it frequently enough, putting normal petrol in a high-performance vehicle could harm the engine. It’s better to follow your manufacturer’s advice if you can.

Does combining 87 and 91 gas work?
On this site, I frequently write about various fuel types. We have not, however, addressed all of the queries. As a result, we’ll utilize this blog to discuss what happens when you blend various gasolines with varying octane ratings. Let’s begin with a brief response:
It won’t hurt vehicles made to run on regular gasoline to mix regular or mid-grade gasoline (87-89 octane) with premium fuel (91-93 octane). Nevertheless, depending on the vehicle, combining different types of gasoline in vehicles made for premium fuel may cause engine knocking and damage to the fuel system.
That, however, hardly provides a complete response to the query. We’ll get into what occurs when you blend normal, mid-grade, and premium gasoline in more detail below. We’ll examine the effects this has on motorbikes, standard gas-capable vehicles, and premium gas-capable cars. We’ll also investigate what occurs when different gasoline types with varying quantities of ethanol are mixed, as well as whether doing so has any advantages. Read on!
