  Synthetic oil causing oil leaks ?


  Synthetic oil causing oil leaks is another commonly spread myth. The truth of the matter is that if all your engine seals and gaskets are in good condition, synthetic oil will NOT leak in your engine. 

  The myth started because on occasion, an engine will leak with synthetic oil, but not dinosaur (Dino) oil. The reason for this is that the smaller molecules of the synthetic are able to get past very small crevices, where the larger molecules of dino oil cannot. But this does not mean that the synthetic oil has caused the leak, it simply has "discovered" an infant leak, and regardless of what oil you are running, this infant leak will eventually grow to a size that will allow dino oil to occupy and pass also. 

  Synthetic oil has not been shown to deteriorate engine seals or gaskets. It is not some evil solvent that will break down sealant, or anything like that. Like was said earlier, it is just a man-made base stock, that is uniform and smaller in molecule size than dino oil. Nothing more, nothing less.

  Upgrade to Synthetic Oil:

  Today's synthetic oils offer us old-car guys a new and better option for cooling our air-cooled wonders. Synthetic oil can improve head temperatures as it withstands higher temps in an air-cooled engine application. But be warned, if you have a small oil leak now, this upgrade will give you a bigger oil leak when you're done.
