Is the "backbone" of Royal Purple's synthetic fluids, really different from additives found in most other synthetics>? I'm curious what is to be made of their "Synerlec" technology From their website: Synthetic oils enable Royal Purple to make superior lubricants, but it is Royal Purple's advanced Synerlec® additive technology that gives its lubricants their amazing performance advantages. Synerlec® additive technology truly is beyond synthetic™. Synerlec® additive technology forms a tough, slippery, synthetic film on all metal surfaces. This proprietary film significantly improves lubrication: first, by increasing the oil film's thickness, and second, by increasing the oil film's toughness, both of which help to prevent metal-to-metal contact. It displaces moisture from metal surfaces and protects all metals against rust and corrosion. It also fortifies the oil against the detrimental effects of heat, which causes oil to oxidize. I recall Castrol SynTec, use to claim their oil had chemical bonding ro engine parts as well. Is this something common in all synthetics? Thanks for any help trying to explain "synerlec"
