Hi guys, I own a 53 reg (2004) Honda civic 1.7 CDTi. Today I accidentally put in 5.11 liters of unleaded petrol (Shell V-Power if it makes any difference). I already had in about 2-3 liter of diesel in the car already (maybe a little more possible 4-4.5 liters). I was told by the gas station attendant that if I then filled the tank up with diesel it would be fine. So I did. I filled the tank with around another 34-35 liters of Shell V-Power Diesel. Will it be OK like the attendant said? Or should I have had it drained?
