Hi TJ,
Thank you for contacting Husqvarna. Yes 89 octane or greater is perfectly fine to use in your trimmer. I would suggest buying the highest grade (octane) gas you can find. As the higher grade has less additives in it and acts as a little bit of a safety net for your engine. Be on the watch for gas running greater than 10% ethanol as alcohol in fuel is a two cycle engines worst enemy. Hope this helps and thank you for using our products.
