Super vs. Super Plus: That's the difference with petrol
Super vs. Super Plus - This is certainly a frequently asked question when refueling. You can find out which fuel you should fill up with and what exactly the difference between the two types is in this practical tip.
Super vs. Super Plus: the difference
The basic difference is the octane number. So that you understand what it is all about, we will briefly explain what this number stands for.
- The main difference between the two fuels is the octane number . This tells you how knock-resistant the gasoline is. The higher the number, the lower the likelihood of uncontrolled autoignition in the engine.
- When the octane number is very high, your engine works more effectively and uses less gas.
- There is a knocking noise in the engine compartment if the gasoline ignites too early. The pressure and high temperatures can also damage the engine.
- In the meantime, however, the modern motors have built-in knock control so that such a problem can actually no longer occur.
- Super / Super 95: The octane number is 95, which is significantly higher than regular gasoline. Lead-containing anti-knock agents were added before 2000, as this should optimize combustion, but this has been prohibited.
- Super Plus: Here the number is 98 and is therefore more knock-resistant than Super 95. This should improve the performance of the engine.
- The so-called gasoline engines all work with Super 95, Super Plus and E10.
- The ethanol content is also crucial. This describes the proportion of biofuel in gasoline. Until 2011, the share was still five percent, for E10 the share is already ten percent. There is a list of cars that can handle E10, otherwise problems may occur with some cars.
- In particular, the new downsizing engines with turbocharging require Super Plus because the knocking is more likely. The performance of the normal Super is also impaired and fuel consumption is increased.
- With Super and Super Plus you usually have no problems if you have refueled incorrectly.
If you use the time to refuel, you can save a lot of money. In the next practical tip, we will show you when you can get the best prices at the petrol pump.
