How is Castrol Syntec different from oil additives and “engine treatments” containing PTFE, graphite, or other non-stick coatings?
In a publicized case Mobil accused Castrol of reformulating its synthetic by substituting other basestocks in place of its synthetic polyaphaolefins (PAO’s). Castrol Syntec is a hydrocracked oil. That’s right, Castrol has replaced the PAO synthetic base stock with hydroisomerized petroleum base stock. Hydrocracking, as it’s called, is the highest level of petroleum refining. Castrol isn’t even a true synthetic yet Castrol ended up winning the battle when the National Advertising Division of the Council of Better Business Bureaus ruled that Castrol could still market its oil as "synthetic" despite their new formulation. Basically, they expanded the definition of synthetics to include Group III hydroprocessed petroleum oil. This high profile case took place because synthetics are recognized as the market’s best hope for growth. Synthetic oil sales have outpaced petroleum oil sales by a wide margin and the gap continues to widen every year. Consumers are getting smarter and demand the best for their vehicles! Read the full story on the Castrol debacle in our informative articles section. Additionally, just as soon as Castrol won this battle, several other oil companies came up with hydroprocessed motor oils of their own and labeled these products to be "100% synthetic", when they still are primarily Group 3 hydroprocessed petroleum oils and not Group 4 PAO synthetics.

First, Castrol Syntec is a fully formulated, highly engineered motor oil from the world-wide leader in lubrication technology. It is not an oil additive or “engine treatment” which many auto manufacturers specifically recommend agains putting in your car’s engine. Second, the exclusive Castrol Syntec ester that provides the feature of unique molecular bonding is precisely engineered liquid lubricating molecule, not a suspended solid like those other compounds. Susnended solids can prvet and oils’ important anti-wear additives from working effectively and they can also clog the oil filter. There are also some pictures showing how Syntec’s molecular bonding works. Basically, the ester the made for the oil is negatively charged at one end. It is atracted to positively charged metal of the engine. When there is no oil pressure, the molecules stay ‘stuck’ to the engine wall, thus “A ‘carpet’ of protection is formed which stays inplace, even after the engine is shut off. The Engine stays pro
