I use 87 in all of my lawn equipment. I have tried 89 in my Red Max trimmer and Husqvarna blower and cant tell any difference.
The differnce is not really in how the equipment performs. Its how long it lasts and how well the carbs and other fuel related components of the engine hold up. A 2 stroke engine will run cleaner and have less carbon build up if used continuously with higher octane gas. The same can be said for 4 stroke engines. The results are also not noticeable in a short amount of time.
