Put unleaded in diesel tank: 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

  1. Ignition off and stay off No starting, no accessory position, no quick test. Contamination still sitting in the tank is the best case, and it lasts exactly until the engine turns over.
  2. Keep the vehicle still Even rolling it a few metres can move fuel toward the pickup. If the spot is safe, the spot is right.
  3. Look after people first Hazard lights on. Passengers out and clear if there is passing traffic. On a forecourt, let the staff know what has happened.
  4. Phone 01293 248666 Give the vehicle, the fuel that went in, an estimate of the amount, and whether it ran. The price comes back on the same call.
  5. Extraction on the spot The tank is drained, the lines flushed, clean fuel added and the system primed — anywhere across SR1 to SR6, DH4 and DH5.
  6. Paperwork and the waste An invoice for you; the contaminated fuel leaves with us as controlled waste under a transfer note.

Rated 4.8 out of 5

From 2,190 Trustpilot reviews. Reviewers consistently pick out arrival times and the fact that technicians talk them through what happened rather than just taking the keys.

Where reviews are critical, it is almost always about price. Rather than ignore that: the call-out is £89 to £199 and the drain £199 to £1,999, quoted in full on the phone before travel, and we would rather lose the job on the call than argue about it on the forecourt.

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.
