What are the primary petrol in diesel car symptoms?

Primary symptoms include loud metallic knocking noises under the bonnet, sluggish acceleration, vehicle misfiring, engine cut-outs at idle, DPF or Glow Plug warning lights, and the engine failing to restart.

How quickly do symptoms show if I put petrol in a diesel car?

If your tank was nearly empty before putting petrol in, symptoms usually start within 1 to 2 miles as raw petrol reaches the high-pressure fuel pump. If the tank was half full, symptoms may take 5 to 10 miles to appear as the fuels mix.

Will putting petrol in a diesel car ruin the fuel pump?

Yes, if driven continuously. Petrol lacks the natural lubricating properties of diesel oil. Running petrol through a diesel high-pressure pump causes severe metal friction, creating fine metal shavings that circulate and ruin common rail injectors.
