## 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.
