For the older Paxton units,you do not need to use their oil.
I believe ATF fluid is fine.
With the Paxtatrac (SP)fluid they said you could get an extra pound of boost pressure.
Now this type of oil is for the older planitary ball drive superchargers,the new ones are direct gear driven.
I do not know about not being able to ship that oil outside of US.
I believe all the new Paxton Novi's use an engine oil pressure (uses engine oil)line then a return line to the oil pan? Just like the Vortecs.
If Paxton had the newer gear griven Novi units I might still be using it, because they would have been able to give me the 20+ pounds (psi) of boost pressure I really wanted.
I know a turbo can easily give me the boost pressure I want,plus I do not need to run a drive belt.
