I have never used the ready mixed gas and oil but there are a couple of things I would look at. One, the Husqvarna equipment requires a 50:1 gas/oil ratio. Is the mix you are using this same ratio? The other thing I would be concerned with is the age of the in the container. Gas can go bad pretty fast and if the gas in the mix is older it could damage your equipment. Again, I've never used the premixed stuff nor have I seen it availbe where I'm from but I would be careful with it.
looking to find the replacement head for the trimmer head for the hus 128LD weed trimmer..best one possible have..ty
Pre-Mix fuel is OK so long as the container indicates the oil used conforms to JASO-FD specifications/requirements.
