Do I actually require premium fuel?
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.
Does premium gas provide better mileage?
Is higher octane fuel therefore more effective? Simply put, no. Paying more for premium gas doesn’t, by itself, improve how well your car runs or how much gas it uses.

Can a BMW run on ordinary fuel?
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:
- It has a turbo engine or one with high compression.
- It’s a model M.
- Your vehicle predates the 1996 model year.
- 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 20122019) 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.
Do premium fuels burn more slowly?
If your engine works just fine on regular, adding premium won’t likely result in any substantial increases in acceleration or fuel efficiency. Whatever you may have heard, conventional gas today has the same detergent chemicals, therefore premium gas won’t do any more to remove deposits from your fuel injectors or other components of the fuel system.
The primary distinction between normal and premium octane is that premium has an octane rating of 91 or higher. Premium gas has a higher octane rating, which makes it more resistant to early gasoline ignition, which could cause damage and occasionally be accompanied by loud engine knocking or pinging. More improved ignition timing, greater compression ratios, or forced-air induction devices like turbochargers or superchargers are all made possible by higher octane fuel. When given quality fuel, they work at their best.
However, you should only use 87-octane regular if the vehicle’s manufacturer specifies that it is all your engine needs. Though technically having less energy than lower-octane fuel, premium gas’ greater octane won’t make your automobile go quicker; in fact, the opposite may be true. When employed in the right engine, the fuel’s capacity to be compressed more without pre-ignition produces higher power. Pricier gasoline is not “more potent gas.
Burning premium because you believe it gives the engine more oomph is likely psychological: “Gasoline prices are higher, so I must be getting more. However, some of that may be the result of favourable weather circumstances (such as warm weather instead of cold) or other causes. Some drivers claim they achieve superior fuel economy with premium.
You are treating the symptom, not the problem, if you use premium fuel because your engine knocks when you use normal. A mechanic should determine what is producing the knock and treat it if it is not carbon deposits or hot spots.
Depending on where you live, premium gas might cost anywhere from 20 to 60 cents extra per gallon. The return on investment will be limited if premium gas is pumped into a vehicle that was made to run on standard gas.
