Straight answer on what we are

A mobile fuel drain operation covering CA1 to CA6. No garage, no forecourt, no Carlisle address. A technician and a van, dispatched by people who know the area, reached on 01293 248666. If that is not what you need, we will say so on the call rather than take the booking.

What percentage of petrol in diesel is ok: what to do

The most common misfuel, and the one with the most to lose by starting the engine.

Why we ask about the engine before anything else

It is not small talk. Whether the engine ran tells us which parts the wrong fuel has touched, and therefore what the technician needs to bring and what the job is likely to involve. A vehicle that never started needs a drain. One that ran needs a drain and a careful look further along the fuel path.

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.

Questions we get asked

How long will I be waiting?

Arrival depends where you are across CA1 to CA6 and what is already running. You get a realistic window on the call rather than an optimistic one.

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.

Can you come to a supermarket forecourt?

Yes, and it is where a good proportion of jobs happen. Tell the cashier a drainer is on the way; they are used to it.

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.
