Biodiesel
Biodiesel is a biodegradable alternative fuel that is mostly made from soybean oil. It can also be obtained from other sources, including canola and yellow grease in some situations. It is safe to assume that since all diesel engines are biodiesel compatible, one may choose to use biodiesel in BMW automobiles even though the company does not explicitly recommend it.
The three most popular varieties of biodiesel fuel are B2, B5, and B20. According to the BMW X5 owner’s manuals, the safe zone is ideally B5 and below. Because anything over B5 is undoubtedly not a safe zone for your engine, anything between B6 and B20 tends to inevitably shorten the service intervals.
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.
Why BMWs Need Fuel with a 91+ Octane Rating
It’s crucial to keep in mind that when you acquire a BMW, you’re getting a high-quality vehicle. If you want to maintain the high performance levels of your BMW, you must take good care of all of its cutting-edge features and innovations. The type of gas you utilize is the first thing to consider.
BMW advises its customers to only use high-octane gas, such as 91+ octane. This will ensure that your BMW operates at its peak performance, but, like with any gasoline option, there are advantages and disadvantages to using 91+ octane fuel.

Nevertheless, depending on the vehicle, blending various types of gasoline in vehicles made for premium fuel could cause engine knocking and fuel system damage.
What would happen if you entered 87 rather than 93?
The best fuel grade for the BMW X5, code-named G05, is AKI 89 or RON 94-95. This X5 is of the fourth generation. BMW does, however, caution against a banging noise while starting the car in hotter conditions without causing any engine damage. For optimal performance, RON 95 and above are recommended.
