So,
Reason for the question and I will keep in real simple, ME being a dealer for synthetic oils for a long while now, al beit almost every car today
requires synthetics, where this comes from is switching to synthetic and switching back to dyno oil "can" cause old seal to shrink.
if everything is correct and one is adding to a new rebuilt engine or existing old seals, you might want to think of replacing the seals. In no way am
I suggesting these are things you should so but Synthetic oils have one benefit in that they "can" cause swelling or expansion of old seal which is
the opposite of leaking.
for all those who like Dyno oil then great keep using them. in some parts of the county we dont have the advantage of benefiting from cheap anything.
quite honestly I am purchasing synthetics cheaper than Dyno oil. FYI oil does not go bad its the additives that have a shelf life. This is for any oil
you use.
In General for the heat and abuse we place on out coach engines you want to change your oil and filter every 5000 miles anyway. Can you go longer on
Synthetic yes but that is each owners personal preference.
