you got several ..ACTUAL ANSWERS, read again.
dagosa told you what he uses.
uncleturbo told you what he uses.
and cigroller told you the advice he got, which I agree with, the brand doesn.t much matter when it's all essentially the same stuff.
I'm reading these and learning in case I might need the additive.
But I haven't yet.
My mower and weedeater are electric. I don't have a generator, boat, chainsaw, atv, skido, dirt bike, or go kart.
The only potential old gas I have to pre-treat is in my 79 that I put gas into about once every two years.
In that I use the red Staybil and have had no problems.
