Iwould find what is readilly available to you locally that meets the requirements shown in the engine manual. As long as it meets those standards and is a quality fuel from a reputable manufacturer, you'll be fine.
You'll find that people in this hobby get very passionate about the subject of fuel brand, radio brand, oil type, engine brand and so on. I guess it is human nature to get defensive whenever someone suggests they like something better than what you prefer. Such question scan often cause some heated discussions

. It is almost like two people arguing over their preferred brand of beer or two drunken NASCARfans going at it in a Ford vs. Chevrolet debate. Truth is, most all of them will work.
Ipersonally like Coolpower fuel. Not sure if it is available in Ireland or not but you might give it a try if it is.
