I'm pretty sure that's the same oil I used for a few years. It's decent oil, but I recommend you do NOT use it for pre-mix. I switched to Stihl Ultra and could clearly see a performance/cleanliness improvement over it. I have a few bottles left (I use the small bottles to mix one gallon at a time) but I have relegated it to bench use for lubrication. I use it to lube up wrist pins, new pistons, etc., but for nothing else. I have not observed any visible "break-down" of the oil (the remaining is probably two years old or so), but after using the Ultra for a while, I'm convinced I'm done using it [Echo] for pre-mix. Not bad really, just there are better oils out there. It's inexpensive to buy good oil for pre-mix, so why take the chance of damaging a top end due to poor lubrication? Use it for assembly lube only is my suggestion.
