I think the question being asked is: "What technically or scientifically does this OTC product add to your oil that a properly selected engine oil of the correct viscosity, application, and specification does not have?"
There is nothing snobbish or judgmental when asking about the technical aspect of an oil or additive.
So whether it is HyperLube, STP, Lucas, or any other external additive, one should avoid arguing from an irrelevant, emotional response
, but rather provide a reasonable
technical explanation as to why this purchase was made.
