Practical Advice for Irish Drivers
- Plan Your Route: Use a map or navigation app that lets you insert a fuel stop. Aim for a station in one of the low‑price counties—particularly Cavan or Carlow—if it lies on a sensible detour.
- Fill Early in the Week: Historically, petrol prices today tend to be a touch lower on Monday and Tuesday before a mid‑week bump.
- Watch the Hours: Some independents run “early‑bird” discounts before 9 am. The stations listed above often keep the €1.80 price all day, but it never hurts to ask.
- Keep Your Tank Half‑Full: Diesel engines especially benefit from avoiding a near‑empty tank, which can introduce air into the fuel system and lead to higher consumption.
- Check the Fuel Grade: If you drive a newer diesel vehicle, consider using premium diesel where it’s available; the extra cleaning agents can improve mileage over time.
