What do you do if you put the wrong gas in your car

What do you do if you put the wrong gas in your car? Do not start the engine. The tank is drained, the lines are flushed, fresh fuel goes in and the system is primed where the car stands. Call 01293 248666 — a mobile technician comes to the vehicle anywhere across CA1 to CA6. 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 Carlisle, and that coverage of CA1 to CA6 is a dispatch area rather than a marketing claim. It does not mean a building — Wrong Fuel Carlisle has no premises and never has. Call 01293 248666 and the equipment comes to you.

What do you do if you put the wrong gas in your car: what to do

Mobile drain and flush, on site, usually inside the hour.

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 CA1 to CA6.
  6. Paperwork and the waste An invoice for you; the contaminated fuel leaves with us as controlled waste under a transfer note.

Four point eight, and why it is not five

2,190 Trustpilot reviews average 4.8. Happy customers write about patience: a technician who explained each step instead of hurrying, at an hour when nobody wanted to be standing on a forecourt.

Most of the missing tenth is money. That is understandable, so the numbers sit in plain sight — call-out £89 to £199, drain £199 to £1,999 — and every figure is agreed by phone first, never revealed on arrival.

Questions we get asked

Do you work at night?

Yes, around the clock, every day. A large share of misfuels happen after dark, so the rota reflects that.

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.
