Super or. Super Plus? That is certainly a frequently asked question when filling up. Find out which fuel you should fill up with and what exactly the difference is between the two types in this practical tip.
Super vs. Super Plus: The difference
The fundamental difference lies in the octane number. To help you understand what this 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 how anti-knock the petrol is. The higher the number, the lower the likelihood of uncontrolled spontaneous combustion in the engine.
- If the octane number is very high, your engine will work more effectively and use less petrol.
- There is a knocking noise in the engine compartment when the petrol ignites too early. The pressure and high temperatures can then also cause damage to the engine.
- In the meantime, however, modern engines have a built-in knock control, so that such a problem can no longer occur.
- Super / Super 95: The octane number here is 95 and is thus significantly higher than normal petrol. Before 2000, antiknock agents containing lead were added to optimise combustion, but this has been banned
- Super Plus: Here the number is 98, making it more anti-knock than Super 95, which is said to improve engine performance.
- The so-called petrol engines all run on Super 95, Super Plus and E10.
- The ethanol content is also decisive. This refers to the proportion of biofuel in petrol. Until 2011, the proportion was still five percent; with E10, the proportion is already ten percent. There is a list of cars that can run on E10, as some cars might otherwise have problems.
- The new downsized turbocharged engines in particular require Super Plus, as the likelihood of knocking is higher. With regular Super, performance is also compromised and fuel consumption is increased.
- With Super and Super Plus, you usually have no problems if you have filled up incorrectly.
