Filled up with regular instead of premium or Super Plus?
At a glance: Not an emergency: you can carry on driving carefully. Avoid top speed and heavy loads, follow the manufacturer's instructions and fill up with the right grade as soon as possible. Pumping out is usually not necessary. Not sure? Free advice: 0177 3555403.
If you have filled up with regular instead of premium or Super Plus, you can continue driving carefully.
Follow your vehicle manufacturer's recommendations.
Avoid driving at top speed.
Do not put the engine under load. There is no need to have the fuel tank cleaned (drained). Top up with the correct fuel as soon as possible.
Differences between premium and regular gasoline
Premium and Super Plus: the difference is in the octane rating! Put in the wrong fuel?
- The difference between the various grades lies in the so-called octane rating. It indicates how resistant the gasoline is to knocking.
- The higher the octane rating—and therefore the greater the resistance to knocking—the lower the likelihood of uncontrolled ignition in the engine, known as knocking.
- When knocking occurs, the air-fuel mixture ignites too early. You may hear knocking from the engine compartment, and the uncontrolled pressure can damage engine components.
- Modern engines have a so-called knock control system, which optimizes engine settings to allow operation close to the knocking limit.
What types of gasoline are there? Put in the wrong fuel?
- Premium, also known as Super 95, has an octane rating of 95. That is considerably higher than regular gasoline.
- Super Plus has an octane rating of 98 and is more resistant to knocking than premium. The higher the octane rating—and therefore the gasoline’s resistance to knocking—the more efficiently the engine can run, reducing fuel consumption.
- Regular gasoline is now rarely available.
- In modern cars, the difference between premium and Super Plus has no significant effect on fuel consumption or engine performance.
- In addition to the octane rating, the ethanol content—that is, the proportion of biofuel in the gasoline—is also relevant.
- Until 2011, gasoline contained five percent ethanol. Today, you can also fill up with E10, which contains ten percent ethanol.
- If your car is not compatible with E10, you should use premium, which still contains five percent ethanol.
