It will say what standards it meets on the container. I bel;ieve husk and stihl's(black bottle) new oils meet these specs. Mobile MX2T also meets these specs and is available at Autozone for 3.50 a pint. It doesnt have any of the fuel stabalizers that the oems oils have thoughHow does one tell if the oil they are buying meets ISO-LE-GD or any other standard?
