Google doesn't always know everything.
He can lead you down the wrong, outrageously expensive track.
As an exception, the friend from the old days drove to Munich in his wife's SUV instead of his company car.
This is a petrol engine, the SUV is a diesel.
The wrong fuel was used before the return trip, yes that still happens.
He noticed it relatively quickly, stopped the process and filled up with diesel.
"There was a maximum of 20 percent Super in the tank," he says.
What to do?
He googles and finds the information somewhere in the infinite digital expanse that an admixture of up to 25 percent is okay.
So he drives off and the accident takes its course.
After two kilometers the car is stationary.
Nothing works anymore.
The ADAC comes, tows, get a rental car, the action costs four hours.
Two days later, the workshop sends the estimate: 14,000 euros.
Uff.
So the fact that you can fill up Super with diesel applies at best to old diesel engines, it used to be recommended even in winter to maintain fluidity in very cold weather.
But that no longer applies today.
The modern self-igniters are highly complicated, even small amounts of super in the fuel can lead to the engine no longer being lubricated, the injectors clogging and so on.
Even if you have only filled up a small amount incorrectly: don't take any risks, leave the car at home, don't even activate the ignition, because sometimes fuel will be injected.
Anyone who has the diesel-petrol mix pumped out will get away with a black eye, even if it costs a few hundred.
Incidentally, filling up with diesel instead of petrol is hardly possible,
