According to the "Material Safety Data Sheet" for H-D's SYN3, it is chemically a blend of 60% synthetic and 40% petroleum oils. This is not illegal but it's certainly deceptive. The Courts have ruled that it is legal to advertise a product that has a chemical composition that includes at least SOME synthetic properties as a "synthetic lubricant".. in the case of SYN3, that oil is a 60/40 blend and not a true, 100% synthetic or anything even close to it.
So Its not a true SYNTHETIC OIL.........................F@*cken Sneakey Bastards.
