Well someone’s buying it! Yes most likely chainsaw Charlie’s and scooter kids but I wonder if anyone has the cajones to run an RD on the stuff. Maybe back when our bikes came out this type of oil was a fairly standard choice?
It's JASO rating is FB, that's the lowest since FA which was officially obsolete 2005. It ok for low powered stuff but it's unlikely to meet chainsaw and decent hedge trimmer requirements, they rev far to highly. Think my Echo requires FC or FD and the Stihl likes FD, they are WOT when cutting so it's unlikely those sort of machines will last long using this. Car lube also offer a synthetic which is FC.
Only use Motul 710 now in the bike, probably overkill but my it runs clean on it. Many years back, oils were not so advanced so this might well be better than what some used in their bikes. I wonder what the quality of those in the pump action cylinders was like at petrol stations 🤭
Back in the day a bike dealer who'd just got a huge display of new oil in tried to tell me I should be using Rock Oil cheapest 2T in my RD as 'it is an old bike and the pump needs a thicker oil to work... plus its cheaper too'. Yeah, thanks for that advice. lol

Back when i had my LC, I put whatever was cheapest in it and certainly was sympathetic to the bike, I even did some courier work on it for a bit but she never let me down.
Now we are older and wiser, we can choose something of a better quality and ironically, perhaps ride more with more consideration and cover much less miles, no reason to knock it, not everyone needs or wants to spend a fortune on premium oils and fuels.
