Re: Video on oil and gas additives
Found this on a Porsche forum discussing cylinder bore scoring. At the minimum, please read the comments in purple text. None of the comments below this line are mine.
The motor oil manufacturers each employ dozens of engineers, tribologists (the science of wear, friction and lubrication), chemists, and lab technicians. They have fabulous research and testing laboratories with everything from scanning electron microscopes to engine dynos. They compete against each other, and collaborate with the engine manufacturers to ensure compatibility of the oil to the manufacturers' specifications. The engineers and scientists go to technical conferences and keep up with any new research. They optimize their additive package based on data from computer design-of-experiment computer programs and extensive testing. The additive package and the base oil are blended with parts per million accuracy. Porsche and all reputable car companies publish specifications for fluids including the motor oil. Is it reasonable to believe that dumping in a bottle of unknown chemistry helps? At best you are wasting your money. More likely you are doing harm. The new additive might have compounds that are not compatible with what is already in the oil. For sure, the carefully designed additive blend is upset. Some bullets:
Do your own research from objective sources. If you want more ZDDP or molybdenum disulphide, find a reputable oil with higher concentrations in their blend. Then rest easy knowing you are getting a proven additive package.
