On a forecourt, apply the handbrake and tell the station staff. - Call 01295 380724 with your location, your vehicle and which fuels were mixed. You get the price before we set off. - A technician attends with a licensed drainage unit and makes the area safe. - The contaminated fuel is pumped out and the fuel lines are flushed through. - Clean fuel goes in, the vehicle is started and checked, and you drive away. The waste fuel leaves with us for compliant disposal. [Call 01295 380724 now](tel:+441295380724) ## Prices in Ruthin Call-out is £89 to £199 and the drain itself is £199 to £1,999. The two are quoted separately, and your exact price is confirmed on the phone before a technician sets off. Remote upland and coastal jobs are quoted with travel included, so the figure you are given is the figure you pay. Your situation | What is involved | Typical cost | Time on site | Spotted it, engine never started | Drain the tank, flush the lines, refill with clean fuel | £199 | 45–90 mins | Engine started but not driven | Drain plus a flush of the lines and filter | Mid range | 1–2 hours | Driven a short distance | Drain, flush and a check of the pump and injectors | Higher | 1–3 hours | Driven until it lost power or cut out | Drain, flush and fuel-system diagnosis | Upper end | Assessed on site | AdBlue in the diesel tank | Full drain and flush of tank and fuel lines | Quoted per vehicle | 1–3 hours | [Call 01295 380724](tel:+441295380724) ## Where we attend around Ruthin Our range here takes in postcode district LL15 and the roads that join them, including the Ruthin post town area of Denbighshire. the A55, A525 and A494 carry the van, and the Rhyl and Prestatyn seafronts and the Vale of Clwyd are places we work every week. The car is drained where it is, whether that is a pump, a lay-by, a driveway or a works yard. Postcode on the call gets you the price and an arrival window up front. ## How serious is it? The fuel itself is not really the danger — circulating it is. In the tank it can be pumped straight back out; past the filter it coats parts that no amount of draining will clean in an afternoon. ## What happens when we arrive The tank empties quickly once the unit is connected; the rest of the time goes on flushing the lines and filter properly. That step is what stops the car running rough a week later, so it is never skipped. ### Neighbouring places we cover [Denbigh](/areas/denbigh/)[Mold](/areas/mold/)[Buckley](/areas/buckley/)[Holywell](/areas/holywell/)[Llangollen](/areas/llangollen/)[Flint](/areas/flint/)[Rossett Wrexham](/areas/rossett-wrexham/)[Cefn Mawr Wrexham](/areas/cefn-mawr-wrexham/)[Connah's Quay](/areas/connah-s-quay/)[Penycae Wrexham](/areas/penycae-wrexham/)[Marford Wrexham](/areas/marford-wrexham/)[Gresford Wrexham](/areas/gresford-wrexham/)[Rhosddu Wrexham](/areas/rhosddu-wrexham/)[Borras Wrexham](/areas/borras-wrexham/) ### Elsewhere in Denbighshire [Rhyl](/areas/rhyl/)[Prestatyn](/areas/prestatyn/)[Denbigh](/areas/denbigh/)[Llangollen](/areas/llangollen/)[Kinmel Bay Rhyl](/areas/kinmel-bay-rhyl/)[Rhuddlan Rhyl](/areas/rhuddlan-rhyl/) ### Answers [What do I do if I misfuel on the M4?](/answers/what-do-i-do-if-i-misfuel-on-the-m4/)[What do I do if I misfuel on the A55?](/answers/what-do-i-do-if-i-misfuel-on-the-a55/)[Do you cover Anglesey for fuel drain?](/answers/do-you-cover-anglesey-for-fuel-drain/)[What is the phone number for a fuel drain in wales?](/answers/what-is-the-phone-number-for-a-fuel-drain-in-wales/)[How quickly can someone come out for wrong fuel?](/answers/how-quickly-can-someone-come-out-for-wrong-fuel/)[What do I do if I misfuel on the A470?](/answers/what-do-i-do-if-i-misfuel-on-the-a470/)[Is wrong fuel covered by the AA or RAC?](/answers/is-wrong-fuel-covered-by-the-aa-or-rac/)[Who do I call for wrong fuel in Cardiff?](/answers/who-do-i-call-for-wrong-fuel-in-cardiff/) ### Council areas [Isle of Anglesey](/coverage/isle-of-anglesey/)[Gwynedd](/coverage/gwynedd/)[Conwy](/coverage/conwy/)[Denbighshire](/coverage/denbighshire/)[Flintshire](/coverage/flintshire/)[Wrexham](/coverage/wrexham/)[Powys](/coverage/powys/)[Ceredigion](/coverage/ceredigion/)[Pembrokeshire](/coverage/pembrokeshire/)[Carmarthenshire](/coverage/carmarthenshire/)[Swansea](/coverage/swansea/)[Neath Port Talbot](/coverage/neath-port-talbot/)[Bridgend](/coverage/bridgend/)[Vale of Glamorgan](/coverage/vale-of-glamorgan/)[Cardiff](/coverage/cardiff/)[Rhondda Cynon Taf](/coverage/rhondda-cynon-taf/)[Merthyr Tydfil](/coverage/merthyr-tydfil/)[Caerphilly](/coverage/caerphilly/)[Blaenau Gwent](/coverage/blaenau-gwent/)[Torfaen](/coverage/torfaen/)[Monmouthshire](/coverage/monmouthshire/)[Newport](/coverage/newport/) ## What Welsh customers say Rated **4.8 out of 5** from **6,053** verified reviews on [Reviews.co.uk](https://www.reviews.co.uk/company-reviews/store/fuelfixer-co-uk).

Leave the vehicle where it is and call 01295 380724. **How long does the drain take in Ruthin?** About 45 to 90 minutes on site once the technician arrives. Vehicles that were started or driven take longer, because the lines and filter need flushing as well as the tank. **How much does it cost in Ruthin?** Most jobs fall between £199 and £1,999 depending on the vehicle, how much wrong fuel is in the tank and whether the engine was started. You get the price on the phone before we travel. **Will it have damaged the engine?** Only if it has been run through the system. Caught before starting, it sits in the tank and a drain removes it cleanly. **Does insurance cover it?** Often not. Most car insurance policies exclude misfuelling as standard, though some breakdown policies and optional add-ons include it. Check your own wording. **Do you cover rural and island Ruthin?** Yes. Technicians attend forecourts, roadsides, homes, farms and workplaces across Wales, including the uplands and the islands. Remote jobs are quoted with travel included so the price does not move. ### Other sites in this network Fuel Fixer Wales is part of Stockbridge Capital Holdings › Fuel Fixer International › Fuel Fixer Ltd.
