Purchasing a higher octane rating gas won’t do anything for your car. On the other hand, using a lower octane rating than what is recommended by your manufacturer could cause damage to your car’s engine.
What is the difference between 91 and 95 octane fuel?
What’s the difference between 91 and 95 octane fuel? Put simply, the only difference between these two fuels is their Research Octane Number, with the higher-octane 95 unleaded designed to be more fuel efficient and lead to a smoother engine operation.
Can a fuel have an octane rating of more than 100?
It is possible for a fuel to have a Research Octane Number (RON) more than 100, because iso-octane is not the most knock-resistant substance available today. Racing fuels, avgas, LPG and alcohol fuels such as methanol may have octane ratings of 110 or significantly higher.
What is 87 octane regular?
Blending 87 with 10% ethanol will result in a fuel octane level above 89 hence the lower grade sub-oct for sale as 87 octane regular. You seem to know the actual science behind all this fuel mumbo-jumbo.
Does higher octane make a difference?
These additional processes are what contribute to the higher pricing, but that does not mean the higher octane will offer any advantage over other blends in many engines. Octane does not offer any better fuel mileage, increase engine horsepower, or make the engine start quicker. Higher octane only reduces the likelihood of engine knock or ping.
Can I use 93 octane instead of 91 BMW?
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 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.

Which petrol is better 95 or 97 octane?
The main difference between RON97 and 95 is that RON97 will have higher resistance to knocking on higher pressures in a high-performance engine, which prevents knocking. At the same time, the RON95 is good but will still produce knocking if your car has powerful engines.
Is 98 octane petrol better?
By filling up with higher octane fuel you might be giving your engine a helping hand to work more efficiently, but it is not a silver bullet for all motors. Depending on the car you own, fuelling up with 98 octane will result in increased performance that will see you produce a little extra power when compared to lower octane petrol.
Should I use higher octane fuel?
Some cars specify the use of higher octane fuels but drivers are unlikely to see any fuel efficiency benefits, particularly as they will be paying around 14p more a litre for super unleaded. Should I use a premium fuel? Again, this depends on your car.
