If you have a 10W-30 mineral oil, that means your base oil has measured to flow between 9.30-12.49 Cst’s @ 100°C.
If you take a synthetic 10W-30 base oil, that means your base oil(synthetic) has also measured to flow between the same 9.30-12.49 Cst’s @ 100°C.
Follow me so far?, so we now know both oils have the same basic oil flow properties as each other which means that they are pretty much equal in flow
