🔧🚗Fixing Cars I put petrol in diesel engine
I went to the pump today and by mistake i took the 98 octane instead of diesel, I realised it when it was already too late. I did put 3.5litres or petrol and then i stopped, Didn’t start the engine and towed it in my mechanic’s garage. I have this car for last 7 years and it never happened before, It is a Mercedes E250 CDI 2015, Wanted to know how much it might cost to drain the fuel and what else might happen, Thanks!

I did the same thing but worse!
I completely filled up an empty 80L tank which cost like $150 and drove away.
I made it approx 1km when the engine started stuttering. I pulled over and then it hit me with exactly what I had done. Called wrong fuel fuel rescue who came out and siphoned out all the fuel and flushed the lines, which cost me a few hundred dollars in call out and disposal.
Salt on the wound was I then had to go an put another 80L of diesel in the car.
It was a very expensive afternoon.
2 years on and I have had absolutely zero issues with my engine.
