A local number, not a local building

The number at the top of this page is answered by the people who send technicians to Middlesbrough. That is what the word local is doing here. It is not standing in for a depot, because Wrong Fuel Middlesbrough does not have one — the van comes to TS1 and TS3 to TS8 and the work happens where you are stood. Call 01293 248666.

Can i put a small amount of petrol in my diesel car: what to do

Five litres, twenty litres, a splash — why the amount matters less than the key.

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

  1. Freeze, then think The reflex is to start up and drive somewhere sensible. Resist it. Nothing about the situation gets worse while the engine stays off.
  2. Where you are is fine A forecourt bay, a kerb, a car park: all workable. Only move if staying put is genuinely dangerous.
  3. Hazards and a quick word Switch the hazards on and tell anyone who needs to know — cashier, passengers, the driver behind.
  4. Ring 01293 248666 with four facts Make, wrong fuel, rough quantity, started or not. Those four facts set the price you are quoted before dispatch.
  5. A technician arrives equipped Pump, sealed waste drum, fresh fuel and priming kit all come in the van. Nothing is towed.
  6. Drive off, document in hand About an hour for a typical job, then a waste transfer note for the old fuel, which is worth keeping.

Ratings, praise and the one recurring grumble

4.8 out of 5, drawn from 2,190 Trustpilot reviews. Praise centres on dependable timing and technicians who keep things friendly when a driver is stressed.

The grumble is cost. Rather than soften it: £89 to £199 covers the call-out, £199 to £1,999 covers the drain, and quoting happens over the phone, before travel, every time.

Questions we get asked

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.

Can I just top it up with the right fuel?

No. Dilution does not fix contamination, and driving to a filling station to try it is the mile that turns a drain into a repair.

What happens to the old fuel?

It leaves with us as controlled waste under a waste transfer note. It is not tipped, and it is not resold to you.

Is this a garage?

No. Wrong Fuel Middlesbrough is mobile. A technician travels to the vehicle wherever it is standing.
