Minimum standards yes. Oils can, and do however, exceed those standards and do so to varying degrees via different additive packs, base stocks, etc... There are synthetic oils like Supertech and then there are synthetic oils like Royal Purple, Amsoil, and Redline. While all synthetics I doubt anyone would put Supertech into the same class as those other 3. I sill say the lowest synthetic is a superior product to the highest level conventional. JMHO. The additive packs in some conventional oils may be a bit better than Supertech but overall when all aspects of oil are factored in the synthetic, IMO, is superior.
