Apparently, it does get better..."If repeat use is desired"...this oil must magically refill when the FunLPro hose is collapsed!!!
OP, I wouldn't recommend this based on the missing approvals/specs.
Edit - Oddly enough, I don't see this brand listed on the current NMMA list that the label says both it "exceeds" and at the bottom claims to be "Certified"
