I've put 10l of petrol in my diesel car realized then filled it up with 33l of diesel what should I do?

can you tell me the make and model of the car please?

basically I need to know the fuel tank capacity

as you can get away with about 15% petrol in diesel will no ill effects

so for you to be alright your tank capacity needs to be 65 ltrs and you need to brim it with diesel

Mercedes A class 2012
I think it's 50 l ?
OK the Mercedes A class for this year has a 60 ltr tank

So ideally you need to siphon some of the contaminated fuel out (10-15 ltrs or so), then top up with fresh diesel to be safe

do you still need help with this?
