Gasoline Options For A BMW 5-Series (Explained)
This blog will explore the fuel-related features and specs of the BMW 5 Series, including the types of engines and the suggested fuels for each. The additional gasoline types that can and cannot be used, the combined, highway, and city miles per gallon, the fuel tank size, and the cost of filling up your BMW today will also be discussed.
All BMW 5-series generations need premium unleaded fuel with an octane value of 91 or higher. Additionally, this fuel is advised for hybrid engines created after 2018. Ultra-low sulfur diesel is suggested for 5-series vehicles with diesel engines.
Now that we have a thorough understanding of every engine option accessible, let’s check what fuel each one uses. Keep in mind that using the incorrect fuel type for an extended period of time might harm your engine irreparably, causing it to fail before its time.
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.
Does 87 octane fuel work in a BMW?
The quick response is: NO! We do not advise using subpar fuel in BMWs. When reading the owner’s manual for some models, this might seem like a good alternative, but Triangle Imports doesn’t subscribe to that way of thinking. The potential harm that conventional petrol could do to your car is simply not worth it.
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 is the best gas station for a BMW?
The addition of ethanol to petrol has become customary as a result of our continually growing dependence on oil. The main purposes of ethanol are to assist oxygenate the fuel and serve as a consumable, re-usable filler. The fuel known as E10 must contain 8–10% denatured ethanol to meet Top Tier regulations. Non-Top Tier fuels can range, and when too much ethanol is present, water is absorbed and over time accumulates at the bottom of the fuel tank beneath the lighter floating gasoline, which can cause rust and drivability problems. Although it is true that for the past ten years, the majority of BMW gasoline tanks have been made primarily of plastic, therefore rust is typically not an issue. By preventing deposits on fuel injectors, combustion chambers, and intake valves in particular, high-quality additive packages for Top Tier fuels assist in the maintenance of your engine’s internals (non-direct injection).
Do I need premium gas for my BMW 5 Series?
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.
Will my BMW be damaged if I use ordinary gas?
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.
Can I fuel my BMW with 93 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.

Are BMWs prone to breakdowns?
The only fully electric BMW in this study is the i3, which is also the first mass-produced electric vehicle to leave Germany and the only fully electric BMW on the market in 2019. The producer will launch a number of new electric vehicles in 2021, including the BMW ix3.
Despite the fact that there are over 17,000 of these vehicles on UK roads, ReliabilityIndex was unable to compile an accurate performance report due to a lack of data.
The Which? consumer reliability survey included more than 55,000 participants, and with this number of responses, there was enough information from BMW i3 owners to create a comprehensive picture of the car’s dependability.
A remarkable 16% of newer vehicles contain faults (which, in comparison with other BMW models and other brands, is good). When they do have problems, they are also quite quickly fixed; the average downtime for an i3 in the 12 months before to the poll was just one and a half days.
The number of cars that had a fault so severe it forced them off the road entirely was 4.4%, despite the fact that the fault rate is well below average (which is positive). Although this is higher than the industry average for more recent electric vehicles, the entire % needs to be viewed as a number as with other data-based statistics. Less than 1% of all new BMW i3 owners are actually impacted by the breakdown rate, which is only 4.4% of the 16% total recorded issues.
Serious motor troubles, which can occasionally result in a full motor failure, and ventilation system problems are the most frequent problems that i3 owners report.
According to statistics gathered by Which?, 36% of owners of older i3 models (between 3 and 8 years old) reported having a problem with their car. 7.4% of owners reported having trouble starting their cars. The i3 is not like many older automobiles, which require much more time to fix than their more modern rivals. Owners were without their cars for an average of two days when the vehicle needed to be taken in for maintenance (only half a day longer than when their vehicles were new).
The engine electrics were the main problem customers had with an older generation i3. 15% of owners who experienced a problem determined that this was to blame. Battery charging issues were reported by a very tiny percentage of owners.
Overall, evidence obtained from current owners of the i3 by Which? indicates that it is a dependable electric vehicle. Due to this, the upgraded model received four out of five stars in the 2020 consumer report. Older models only received two stars out of five since they were not thought to be as dependable, had more major breakdowns and troubles, and were not thought to be as desired.
The i3 is a model that you may be considering if you want to go electric, and its reliability makes leasing a new car a very appealing option. Especially when you consider the stark disparity in reliability between the newer and older versions.
