Synthetic oil vs. non synthetic oil

Posted by Al On 2011/12/28 9:12:46
It seems the newer synthetic oils work so well, that they actually promote the leakage in the rear main rope seals.
There are a couple oil products that are not a synthetic blend such as Pensoil "High milage", that seem to retard and/or stop leakage after a while.
Any thoughts?
