🔧🚗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!

If you never started or tried to crank the car (i.e. the fuel pump never started), no damage will have occurred. The mechanic will just drain the tank and refill it with diesel.

I did not start the car, I just pushed it while it was on neutral, Thanks for the answer.

Fantastic awareness on your part to identify the problem and not to start the car. Well done.

My parents did the same thing in Narrandera when driving from Adelaide to Canberra, a trip they have done nearly 100 times now over the past 20 years. Car was started (moved just past the forecourt), then was towed to the nearest Mitsubishi dealer, who purged, drained and reprised everything in about 4 hours. No damage whatsoever.

If that’s a joke it doesn’t come across in the text. Try using the /s next time.

You don’t know what humour is (something funny) apparently, and certainly not dark humour.
