Hi guys, I usually run all Shindaiwa handhelds and like pretty much all new equipment runs 50:1 mix. My neighbor recently passed away and his wife gave me a lot of his old tools. I acquired a Makita 125 string trimmer. It is in great shape and works great so I have been using it mostly for my lawn accounts. When I first got it I filled it up with my usual 50:1 mix and it worked fine then my father noticed that it said 25:1 on the cap!! So I have been running 25:1 and it is working fine but I am using 5oz per gallon of gasoline! Does anybody have a 25:1 ratio machine? And is it OK to run these machines with a lesser oil ratio with todays more advanced oils? Thanks for the help I really appreciate it.
