Local drainer for gasoline in diesel in St Austell
Do not turn the ignition, not even to check the dashboard. For gasoline in diesel anywhere in St Austell, a drainer attends with a pump and a sealed tank, empties the fuel system and refills it. From £89 call-out, usually 45 to 90 minutes on site; ring 01295 380724 for the price before you commit.
Here is why it matters. Gasoline is petrol. In a diesel engine it thins the fuel and takes away the lubrication the pump and injectors need.

From the drainer's notebook
Fuel Fixer, the company behind Wrong Fuel Drain, holds a rating of 4.8 out of 5 from 2,190 reviews on Trustpilot, on a profile claimed since 2017.
Across recent reviews, the themes customers raise most often are staff who stay polite, professional and reassuring during what is a stressful situation, and how quickly a technician arrives and gets the vehicle back on the road in St Austell.
The most common criticism is price. Some customers have felt the cost of an emergency drain was steep for a job that takes under two hours, and that is fair comment on an emergency call-out. It is why the misfuel call-out fee now starts at just £89 and why the full figure is quoted on the phone before a technician sets off — so nothing about the cost is a surprise at the roadside.
Common questions
The engine is running rough — is that the wrong fuel?
If it started shortly after filling up, very likely. Pull over when it is safe, switch off and call 01295 380724.
Can you drain a hire car or a company car?
Yes. Tell the hire company or fleet manager too; many prefer a drain on site to a recovery.
Do I need to stay with the car?
Ideally yes, so the drainer can confirm what happened and hand the keys back. If not, agree access on the phone.
Do you cover all of St Austell?
Yes — forecourts, roadsides, homes and workplaces across St Austell and the surrounding area.
What if I have already driven home?
Leave it on the drive with the engine off and call 01295 380724. The drainer can do the whole job at your house.
Will you bring fuel?
Yes. The drainer adds enough of the correct fuel to start the engine and reach a filling station.
