Mobile across CA1 to CA6

Wrong Fuel Carlisle has no garage in Carlisle. A technician covering CA1 to CA6 drives to the vehicle with everything needed to drain, flush, refill and prime it on the spot. Call 01293 248666. If we cannot safely do the job where you are, you will be told that on the phone rather than after we arrive.

How to tell if you ve put diesel in a petrol car: what to do

Rarer, less destructive, still needs draining.

The pump that pays for the mistake

A modern diesel high-pressure pump is machined to extremely fine tolerances and relies on the diesel itself to stay lubricated. Petrol is a solvent, so it removes that protection. The pump keeps turning, wears, and sends particles toward the injectors. Every part of that chain begins with the ignition.

Step by step

  1. Leave the key alone This is the one that decides the price. Wrong fuel sitting in a tank is a drain; wrong fuel that has been through the engine is a different job.
  2. Do not push or coast it Moving the vehicle can slosh contaminated fuel toward the pickup. Leave it where it is unless staying there is unsafe.
  3. Make yourself safe Hazards on. On a forecourt, tell the cashier — they will almost always let you stay put once they know a drainer is coming.
  4. Call 01293 248666 Tell us the vehicle, which fuel went in, roughly how much, and whether the engine ran. You get a full price before anyone sets off.
  5. We drain, flush and prime Tank emptied, lines flushed, fresh fuel in, system bled and run up before we go.
  6. You drive away Most jobs finish on site in about an hour. The old fuel leaves with us under a waste 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

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.
