The debate between Synthetic vs Dino will never end, users on both sides have made valid arguments, which makes the average Joe even more confused. Dino users say that it clings onto the surfaces much better than synthetic and synthetic users say that the molecules are much smaller than Dino so they are able to go were Dino can't, which could result in leaks. Dino users have had great results as well as Synthetic users. Is one better than the other, I don't know. But what I know everyone will agree on is running a clean , quality oil is much more benifically than the type of oil. I would think that Dino oil would have to be changed more frequently than Synthetic based on claims that Synthetic oil creating less friction, which would offset the cost to some degree. Use what makes you happy and if you become unhappy use the other.
