Ireland — how this works

Fuel Fixer Scotland is a Scottish operator. We do not run our own vans in Ireland, so we do not pretend to: what we do is take the call, work out exactly what has gone into which tank, and put you straight through to a wrong-fuel drainer covering your town.

The advice on this page is the same either side of the Irish Sea, because the mechanics are: do not start the engine, do not move the vehicle, and get the wrong fluid out before anything is run through the system. That part does not change with the jurisdiction. What does change is the waste regulator — in Ireland that is the EPA and the local authority, not SEPA — and the drainer who attends will issue their own paperwork.

Call 01295 380724 and say where you are. If we cannot get someone to you, we will tell you that on the phone rather than take a booking we cannot keep.

What can go into the wrong tank

Wrong fuelWhatever went in the tank comes out before the engine runs. One call, one technician, one visit, anywhere in Scotland.Petrol in a diesel carPetrol strips the lubrication diesel gives the pump and injectors, so it has to come out before the engine runs.Diesel in a petrol carDiesel will not ignite on a spark, so the engine misfires, smokes or refuses to start. A drain normally resolves it.AdBlue in the diesel tankAdBlue is corrosive to fuel-system components. It is a contamination problem and needs a full drain and flush.Unleaded in dieselUnleaded is petrol. In a diesel tank it strips the lubrication the high-pressure pump and injectors rely on.Red diesel in a road vehicleRed diesel in a road vehicle is a mechanical problem and an HMRC problem at once. It is drained, flushed and disposed of under licence.Contaminated or bad fuelWater, diesel bug, debris or stale fuel behaves like a misfuel. Same fix: full drain, flush, clean fuel in.Mobile fuel drainThe contaminated fuel is pumped out where the vehicle stands, the lines are flushed and clean fuel goes in. No tow, no garage.Fuel doctorA fuel doctor is a mobile wrong-fuel specialist. We attend, diagnose, drain and flush where the vehicle stands.MisfuellingMisfuelling is the trade word for putting the wrong fuel in. It is fixed on-site with a drain and a flush.Symptoms of the wrong fuelMisfire, smoke, knocking, loss of power or a refusal to restart shortly after filling up. Pull over, switch off, call.What a fuel drain costsMost jobs fall between £150 and £1,500. The price is confirmed on the phone before a technician sets off.Damage, repairs and insuranceCaught before starting, damage is rare. Once the engine has run, the pump and injectors are involved and the job grows.Wrong fuel in a van, HGV or fleet vehicleCommercial vehicles carry more fuel and cost more per hour off the road. Vehicles over 3.5 tonnes are quoted separately.Wrong fuel in a boat or marine tankMarine tanks are large, baffled and often below deck. Fuel is uplifted quayside or afloat and taken away under licence.Screen wash in the AdBlue tankScreen wash dilutes the urea solution and the SCR system reads it as out-of-spec AdBlue. The tank is drained and flushed before the dosing pump is run.AdBlue in the screen wash tankAdBlue in the washer bottle crystallises in the jets and lines and leaves a white residue on the glass. The bottle and lines are flushed out.Diesel in the AdBlue tankDiesel contaminates the urea solution and can damage the SCR catalyst and dosing system. It is drained before the engine is run.AdBlue in the petrol tankAdBlue is water-based and corrosive to fuel-system components. In a petrol tank it needs a full drain and flush before starting.Petrol in the AdBlue tankPetrol in the AdBlue tank contaminates the urea and risks the dosing pump and SCR catalyst. The tank is drained and flushed.Water in the diesel tankWater sinks below the diesel and gets drawn into the pump, where it strips lubrication and corrodes injectors. It is drained and the tank dried out.Water in the petrol tankWater in petrol causes misfire, hesitation and a refusal to start. The tank is drained, the lines flushed and clean fuel put in.Water in the AdBlue tankAdBlue is already a precise 32.5% urea solution, so added water puts it out of spec and the system flags a fault. The tank is drained and refilled.Water in the screen wash tankPlain water in the washer bottle freezes, splits the bottle and blocks the jets. It is drained and refilled with proper screen wash.Screen wash in the petrol tankScreen wash is water and alcohol. In a petrol tank it will not burn properly and needs draining before the engine is started.Screen wash in the diesel tankScreen wash strips the lubrication diesel gives the high-pressure pump, exactly as petrol does. The tank is drained and flushed.Wrong fluid in any tankWhatever went into whichever tank, it comes out before the engine runs. Fuel, AdBlue, screen wash, coolant or water.

Common questions

Do you cover your town yourselves?

No. Fuel Fixer Scotland operates in Scotland. For your town in Ireland we connect you with a local wrong-fuel drainer rather than sending a van across the Irish Sea. Call 01295 380724 and we will make that connection.

What should I do right now in your town?

Exactly what you would do anywhere: do not start the engine, do not move the vehicle, and call for a drain. Starting it is what turns a straightforward drain into a fuel-system repair, and that is true in every country.

What will it cost in Ireland?

The local drainer sets their own price, so we will not quote you a figure we do not control. As a guide, the equivalent Scottish job runs from £150 for a straightforward drain. Ask the attending drainer to confirm before they travel.

Who regulates waste fuel in Ireland?

The Environmental Protection Agency and the relevant local authority, not SEPA, which covers Scotland only. The drainer who attends is responsible for their own waste documentation.

Is wrong fuel any different in Ireland?

Mechanically, no. The same fluid in the same tank does the same thing to the same components. Only the response arrangement and the waste paperwork differ.

Why does a Scottish company have a page for your town?

Because people in your town search for this and end up on Scottish and UK sites anyway. We would rather tell you plainly what we can and cannot do than take the call and disappoint you.
