## Why misfuelling happens in Troqueer
Troqueer sits across the DG2 postcode district and the A710, with New Abbey, Kirkbean, Southerness and Lochside next door. A large share of local calls come from drivers who have recently switched from petrol to diesel, or the other way, and reached for the nozzle out of habit.

The A75 shapes misfuelling here. A large share of the traffic is holiday and freight movement heading for a sailing, in hire cars, motorhomes and tractor units, on an unfamiliar route, often at unsociable hours with a clock running.

The asymmetry is physical. A petrol nozzle fits a diesel car; a diesel nozzle usually will not fit a petrol one. That single difference in nozzle diameter accounts for most of the imbalance in the jobs we attend.

When it happens: Tied to sailing times rather than rush hours, which is why the overnight and early-morning share is much higher here than on a comparable English town's roads.

## Troqueer petrol in diesel: what to do
The most common misfuel, and the one with the most to lose by starting the engine.

## Three questions that tell us most of the story
Did the engine start? How far did it run? Which fuel went in? The first two describe how far contamination has travelled along tank, lift pump, filter, high-pressure pump and injectors. The third describes how it behaves along the way: petrol thins the lubrication a diesel pump needs, while diesel in a petrol engine fouls plugs and injectors instead.

## 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 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.

## What people actually said
4.8 out of 5 from 2,190 Trustpilot reviews. Two themes dominate the positive ones — how fast someone arrived, and how calm they were about it.

The recurring negative is price. Publishing that alongside the answer seems more useful than hiding it: £89 to £199 for the call-out, £199 to £1,999 for the drain, the total quoted before a technician moves, and no charge for being told on the phone that this is a job for a workshop.

## Questions we get asked

**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.

**Is there an out-of-hours surcharge?**
The call-out is the call-out. Whatever the total is, you hear it on the phone before anyone travels.

**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.

**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.
