Lucas makes some good products. I feel certain it meets or exceeds the OEM requirements. There are many others out there also. Make sure its for air cooled engines
oh my! I can't type that good lets start here semi synthetic oil vs fully synthetic vs regular oil - Google Search
Semi synthetic is usually a blend of synthetic and dino oil versus a full synthetic that contains 0 dinosaurs.
It seems that some synthetics just have the dinosaurs distilled out of them? Some are made from natural gas or methane.
Have always considered Lucas to be quality stuff. I have no scientific basis, just what I've seen & heard. I prefer big 3 oil (stihl, husq or echo), but would run this without fear. https://lucasoil.com/pdf/SDS_Semi-Synthetic 2-Cycle-Oil-10058.pdf
I use it... my bottles don't look like that. I get mine from Orielly's... I use it at 32:1 since I have ported saws, just added protection...
