Q: Accidentally put diesel in a gasoline engine.

asked by on

I accidentally put diesel in my gasoline engine car. What do I need to do to fix this?

We recommend a full drain for any amount of contamination, but if you have put in 2 litres or less of diesel in a petrol car (less than 5% of a full tank) and then fill up your remaining tank with petrol, there should be no damage caused to your vehicle. If it’s more than that, I would have a technician drain the tank.
