## I put unleaded in my diesel car: 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
Stop. Do not turn the key Whatever else happens, this is the decision that matters. Contamination only travels under power.
- Resist the urge to move it The instinct is to get out of the way. Unless you are somewhere dangerous, staying put is the cheaper instinct to follow.
- Safety before diagnosis If you are on a live carriageway, get out and get behind the barrier, and let the police or National Highways deal with the lane first.
- Phone 01293 248666 You will be asked four questions and given a price and an arrival window. Both are honest rather than flattering.
- On-site extraction The tank is emptied, the feed lines are flushed, fresh fuel goes in and the system is primed and run.
- Done, and the waste leaves with us Under a waste transfer note. It is not tipped and it is not sold back to you.

## 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.

**Do you cover all of TS1 and TS3 to TS8?**
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.

**Do I need to stay with the vehicle?**
Usually yes, so we can hand it back to you running. If you cannot stay, say so on the call and we will work out how to do it.
