Mix petrol and diesel
Mix petrol and 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.
Local, mobile, and not a garage
There is no Wrong Fuel Sunderland premises, and we would rather say so than let a local name imply a local building. A technician covering SR1 to SR6, DH4 and DH5 travels to the vehicle — forecourt, driveway, car park or verge. Call 01293 248666 and you reach the people who dispatch to Sunderland, not a national queue.

Mix petrol and diesel: what to do
The most common misfuel, and the one with the most to lose by starting the engine.
The mechanical reason the advice is always the same
Every drainer tells you not to start the engine, and it is not a sales line. The fuel path runs tank → lift pump → filter → high-pressure pump → injectors, and contamination only moves along it under power. Stationary, the problem stays in the tank where it is cheap to remove. Under power, it spreads into parts that are not.
Step by step
- Key out, hands off An engine that has never run on the wrong fuel is a drain and nothing more. That is the cheapest outcome available and it is still on the table right now.
- Do not move the vehicle Not into a bay, not onto the verge, not around the corner — unless it is genuinely unsafe where it is.
- Hazards on, tell someone Forecourt staff are used to this and are rarely difficult about it once they know how long you will be.
- Call 01293 248666 and be specific Vehicle, wrong fuel, rough quantity, engine started yes or no. Those four things determine the price, and you hear it before we travel.
- Drain, flush, refill, prime Carried out where the vehicle stands, anywhere across SR1 to SR6, DH4 and DH5.
- Back on the road About an hour for a standard job. The waste fuel is removed under a transfer note that discharges your duty of care.

What drivers tell other drivers
4.8 stars, 2,190 Trustpilot reviews. The advice drivers pass on is simple: do not start the engine, ring, and expect someone level-headed who knows exactly what to do.
The warning they pass on is that it is not cheap. Fair enough — the call-out runs £89 to £199, the drain £199 to £1,999, and both are stated before a van leaves, so nobody is surprised at the roadside.
Questions we get asked
Is there an out-of-hours surcharge?
The call-out is the call-out. Whatever the total is, you hear it on the phone before anyone travels.
Do I need to stay with the vehicle?
Usually yes, so we can hand it back to you running. If you cannot stay, say so on the call and we will work out how to do it.
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.
What about a van or a hire car?
Same job. With a hire car, ring the hire company too — some policies cover a misfuel drain and it is worth knowing before you pay.
