--- title: Diesel in petrol in Southampton: local drainer from £89 url: https://wrongfueldrain.com/diesel-in-petrol/southampton/ focus: diesel in a petrol car southampton phone: 01295 380724 updated: 2026-10-06 --- # Local drainer for diesel in petrol in Southampton **Short answer** If the engine has not run, diesel in a petrol car in Southampton is usually a clean drain with no lasting harm. Keep it that way — don't start it — and ring 01295 380724. The call-out is £89, the drainer brings everything, and most jobs are done in 45 to 90 minutes. A petrol engine lights its fuel with a spark, and diesel barely lights that way, so you get misfiring, smoke and eventually a car that will not start.

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 Southampton. 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 van or a lorry?** Vans, yes, routinely. Vehicles over 3.5 tonnes are quoted separately because of the volume involved. **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. **What does it cost in Southampton?** The call-out starts at £89. The full price depends on the vehicle and how far the fuel got, and it is confirmed on 01295 380724 before anyone travels. **Will my engine be damaged?** Not if it has not been started. The wrong fuel sitting in the tank touches nothing that a drain cannot clear. Damage starts once it circulates. **I only put a little in — do I still need a drain?** In most modern diesels, yes. Even a small amount of petrol reduces the lubrication the pump depends on. A drain is cheap compared with a pump. ### Who you are dealing with Wrong Fuel Drain is a brand of [Fuel Fixer Ltd](https://www.fuelfixer.co.uk/) (company number 08520551), a company of Fuel Fixer International, the multinational group behind this website.
