As with CD-2 Heavy Duty Oil Stabilizer, the name Lucas Synthetic Oil Stabilizer implies that engine oil is not itself stable. Therefore, the product must be added to the oil to stabilize the oil. Which of course is an absurd claim. The marketing of this kind of worthless product is craftily based on the fact that men are
hard-wired with an innate need to constantly search for additives to gas and oil that will improve performance, decrease wear, increase mpg, clean the engine internals, and etc., etc. All for a modest layout of $2-$10.
