It is my understanding that ANYTIME you switch brands of oil - whether dino to
dino, dino to syn, syn to dino - you will get a similiar reaction. This is
supposedly due to the fact that each vendor uses a different combination of
detergents and you are seeing a cleaning effect of the newer detergent type.
After seeing the typical scuffing in the lower portions of my cylinder walls
(113k miles later and all dino) - I have to mention the comment in my Mopar
Performance Magnum Engines book about them not recommending pure synthetic oils
due to their lack of sulphur which apparently helps deter scuffing. I wonder
what my cylinders would look like now if I had used synthetic oil all that
time... On a race car - who really cares about a little scuffing - its kinda
expected as they are beat on harder -BUT- on a daily driver that is expected to
last alot longer than 100k miles??? I dunno...
