What happens when you put unleaded petrol in a diesel car: what to do
The same failure, under the wording on the pump.
Why the engine matters more than the litres
People assume a splash is fine and a full tank is a disaster. It is the other way round. Wrong fuel sitting in a tank is inert — it is a drain. Turn the key and it travels: lift pump, filter, high-pressure pump, injectors, and every stage it reaches adds a component to the bill. Five litres burned is worse than fifty litres left alone.
Step by step
- The single rule Leave the engine off. Everything else on this list is secondary to that one instruction.
- Do not reposition the car Pushing it into a bay feels considerate but it disturbs the fuel. Stay put unless you are in danger.
- If it is dangerous, get out On a verge or live road, everybody out on the side away from traffic and behind the barrier. Then call.
- Call 01293 248666, day or night Answered around the clock. Describe the vehicle and what happened; the full price is confirmed on that call.
- The fix, where you stand Drain, flush, refill, prime and run-up, carried out at the roadside or on the forecourt.
- Finished properly The waste is taken away by a registered carrier with the transfer note, and you get an invoice.
