Common questions

Do you cover Castlederg yourselves?

No. Fuel Fixer Scotland operates in Scotland. For Castlederg in Tyrone 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 Castlederg?

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 Castlederg?

Because people in Castlederg 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.
