What happens if you mix petrol with diesel
What happens if you mix petrol with diesel? The most common misfuel by a wide margin. Do not start the engine — it is drained, flushed and primed on site. Call 01293 248666 — a mobile technician comes to the vehicle anywhere across SR1 to SR6, DH4 and DH5. Call-out £89 to £199, drain £199 to £1,999.
What "local" actually means here
It means the number is answered by the people who send technicians to Sunderland, and that coverage of SR1 to SR6, DH4 and DH5 is a dispatch area rather than a marketing claim. It does not mean a building — Wrong Fuel Sunderland has no premises and never has. Call 01293 248666 and the equipment comes to you.

What happens if you mix petrol with diesel: what to do
The most common misfuel, and the one with the most to lose by starting the engine.
Why we ask about the engine before anything else
It is not small talk. Whether the engine ran tells us which parts the wrong fuel has touched, and therefore what the technician needs to bring and what the job is likely to involve. A vehicle that never started needs a drain. One that ran needs a drain and a careful look further along the fuel path.
Step by step
- Do not start it — that is the whole thing Everything else on this list is detail. This one line is the difference between a call-out and a pump.
- Leave the vehicle where it stopped Pushing or coasting is still movement, and movement is how contaminated fuel finds the pickup.
- Sort out safety Hazards, and get people out of the vehicle if you are anywhere near moving traffic.
- Call 01293 248666 Answered around the clock. Tell us what went in and whether it ran; you get the full price before a technician sets off.
- The job itself Extract, flush, refill, prime, run up, check. Roughly an hour on a standard vehicle.
- Old fuel away, invoice done Controlled waste, transfer note, registered carrier. Keep the note — it is what protects you.

Questions we get asked
Is this a garage?
No. Wrong Fuel Sunderland is mobile. A technician travels to the vehicle wherever it is standing.
What if I have already driven it?
Still call. Most vehicles driven a short distance are recoverable. Tell us how far you got, because it changes the kit we bring.
Do you cover all of SR1 to SR6, DH4 and DH5?
Yes, from one rota — so being at one edge of the area rather than the other changes the arrival window, not the price.
What if it is not safe to drain where I am?
Then we tell you that on the phone rather than after arriving. Being told honestly costs nothing; being told on arrival costs a call-out.
