I use E10 in EVERYTHING. That includes mowers, cars and even a 45 year old classic car and a 63 year old boat.
We were getting E10 for a couple of years before we even knew about it. Then they put the stickers on the pumps.
E0 gives higher mileage, but the cost increase wipes out any savings.
I always had issues with gas weedwackers and chain saws, even before E10. Constant carb problems even though I drained them off season. Now all my other lawn equipment is electric. Problem solved.
IMHO, use Stabil in gas that sits along time, and just take care of your stuff. A neighbor leaves his lawn tractor outside all the time and he forever complains about "that bad ethanol".
