Just to point out that you need to make sure you know what octane rating system the manufacturer is using in their recommendation. This is often overlooked. Most countries use a different rating system (RON) than the USA and Canada (AKI). So if the manufacturer recommends fuel with a RON octane rating of 89 or more, 87 octane fuel in the USA and Canada will easily meet that requirement. Basically, the USA/Canada octane numbers are 4 to 6 less than elsewhere in the world for the same fuel.
I run 89 octane with ethanol (UP TO 10%) in my mowers and my frequently used string trimmers and backpack blowers and non-ethanol canned fuel in my seldom used small equipment such as hedge trimmers and chain saws. Non-ethanol fuel is not available at the pump in my region and I'd go broke running canned fuel in all of my equipment at the rate I use it.
