This two-cycle engine oil has outstanding engine cleaning characteristics, plus “ultra” lubricating qualities that are superior to other two-cycle engine oils. This fully synthetic oil is also highly biodegradable, degrading by 80% in 21 days. We’re so confident this oil will protect your engine, we’ll double your STIHL limited warranty* when you use it. It’s that good. Unopened container shelf life: Four years from the date of filling, in originally sealed containers.
