BMW requires 91-octane fuel at a minimum, with 93 recommended, so we did just that, switching between the common forms of premium gas depending on which state you’re in.
What is the difference between BMW 91 and 93 octane?
The basic difference between BMW 91 octane vs 93 are octane ratings, which are a measure of how much energy each fuel can provide. 93 octane is used in most cars, and BMW 91 octane is used in BMW’s M Series models. The higher the octane rating, the more power that fuel can provide.
What is the difference between 93 and 91 gas?
The octane rating of 93 gas is greater than 91. It also generates more horsepower and has better fuel economy than 91. That is why you should use 93 gas in your vehicle. The only difference between the two is that 93 gas contains 87 octanes or greater, whereas 91 does not have to contain more than 86 octane.
Is 91+ octane fuel the right fuel for your car?
However, it is important to remember that the right fuel, in this case 91+ octane fuel, has some excellent benefits for your car: The fuel designed specifically for use in BMW’s high-compression engines is 91+ octane fuel.
What kind of gas does a BMW use?
Your BMW is packed with innovative features and technologies that need to be treated with care if you want to retain the high performance levels of your BMW. This starts with the type of gas that you use. BMW recommends that their drivers only use high-octane fuel, such as 91+ octane.
Does 95 fuel last longer?
Some argue there’s no difference, while others say that 95 is better for fuel economy and performance – and the answer is both are somewhat correct. Whether or not to use 93 or 95 depends wholly on the car you own, your driving preferences, and the environment in which you drive.
How long does petrol last?
Probably not as long as you think. Once you’ve put fuel in a container you only have a few months before the quality starts to fall away – even less if the fuel is contaminated in any way. Generally speaking, petrol has a shelf-life of six months if stored in a sealed container at 20 degrees – or just three months if kept at 30 degrees.
How long does diesel last?
Diesel, like petrol, is a fuel that can expire. It’s important to store diesel fuel in a container designed to block out heat, water and air, which can speed up the expiry process. Under the right conditions, diesel can last up to twelve months, but by adding a diesel fuel stabiliser, you can make it last even longer. 6
What is 95 octane fuel?
The next step up the octane ladder, 95 octane fuel allows engineers to tune their engines a little more aggressively before causing that uncontrolled ignition (also called pinging or detonation) that can damage an engine internally.
What is 98 RON petrol?
This fuel exists because some engines need a little more octane, but not the full-fat octane experience of PULP. Often called premium unleaded petrol, 98 RON is the fuel you need for high-performance cars with highly tuned engines. But it’s also the fuel specified for many of those modern, small-capacity turbo engines that are in vogue right now.
Does BMW need premium gas?
No matter your model, BMW recommends using only premium-unleaded fuel. That’s not to say your BMW won’t run on lower-grade fuel, but premium-unleaded fuel will maintain its quality in the long run, letting you drive at peak performance consistently.
Do BMWs use premium gas?
Older BMWs and those with high-compression engines, such as turbocharged models, should also be using premium fuel at all times. BMW make it clear that in these scenarios premium fuel is a must. For all other BMWs, premium gas is only a recommendation rather than a requirement.
Can you run a BMW on regular fuel?
While BMW recommends that all cars currently sold in the U.S. use premium fuel, most models are able to run on regular fuel without damaging the engine. The same is not true for older BMW models; BMW vehicles made before 1997 should only use higher octane (premium) fuel.

However, it’s not the same for petrol with a lower octane rating. Using lower octane petrol (92) in a car designed for higher octane petrol (95) is potentially destructive. It’s likely you’ll lose some power, acceleration and fuel economy.
Can a 95 Octane engine run on 92?
Most of the new gasoline engines well run on 92 , in engines specified for 95. Those are equipped with special technologies to diminish the pinging which can be harmful with low octane fuels. The carbon sediment can be high, when use 95 octane on 90 or lower specified engines. (other way) I don’t think this is the case.

What is 98 octane fuel?
The value, which can be 95 or 98, reveals a scale of the anti-knock capability of the fuel when compressed in the engine cylinder. The higher the octane rating, the more compression it can withstand. Filling a car with 98 octane fuel, when it is recommended to use 95 octane fuel will only cause a problem to your pocket, as 98 is more expensive.
What happens if I put 87 instead of 93 in a BMW?

If you usually fill your tank up with 87-octane gasoline and you accidentally put in a higher octane blend (say, 91, 92, or 93), don’t worry. You may feel a difference in the way the vehicle runs and may notice an improvement in gas mileage, but that’s about all that will happen. Is 88 and 87 gas the same?
Is the 93 better than the 87?
You may be able to get 2-5% better in fuel efficiency for the 93 (assuming tuning exists), but likely at 20% more cost. Bottom line is that unless you’re at the track, the 87 will run just fine. If you want a little more oomph drop in the 93 and you’ll see a small boost. Thanks for this. That’s exactly what I’m thinking about.
What happens if you put 88 in a 87 car?
If an automobile engine is built to run on unleaded 87 with 10% ethanol, using unleaded 88 with 15% ethanol will impose additional strain on the fuel transmission system. When someone shifts into unleaded 88, the most typical worst-case scenario is corroded fuel or a congested transmission system.
What happens if I use 91 instead of 95?
Will something happen if I use 91 instead of 95, or vice versa? This thread at StackExchange answers the question. Long story short; there’s little to worry about. At least, not when it comes to types of octane. (Putting unleaded into diesel vehicles or vice versa is a different story, of course. This may necessitate you emptying the tank.)
What octane fuel does a BMW use?
Using 91+ octane fuel gives your BMW a better chance of properly regulating engine temperatures, helping the engine to stay within a safe temperature range and reducing the risk of overheating.

What happens if you mix different octane fuel?
If you put the lower octane fuel in an engine which specifies high octane fuel, will not cause you any major issues on an electronic fuel injected engine because it has a device known as a “knock sensor” which will pull timing. …When you mix different octanes of fuel, you are either increasing or decreasing the octane of the fuel at hand.

Is 92 octane better than 91?
Regular gas is rated at 87 octane in most states, while premium gas is often rated higher at 91 or 93. Fuel with a higher octane rating can stand up to higher compression before it detonates. Essentially, the higher the octane rating, the lower the likelihood that detonation happens at the wrong time.
What is the difference between 91 and 93 octane?
The only difference between 91 and 93 is the alcohol content. Alcohol molecules are relatively small and combine with the molecules of gasoline to slightly increase the octane rating. You can run a higher compression ratio engine on 91 octane without detonation or knocking, for example.
