Mobil 1 jug has no tinfoil seal either, just crack-ring-sealed.
The only large jug has tinfoil seal is antifreeze. Zerex, Peak and Prestone all has tinfoil seal.

My Mobil 1 jugs have tinfoil. May vary place to place.
Some Castrol Oils have the foil seal.
I picked up 2, 1 Gallon Jugs of Castrol High Mileage, SM oil. on clearance for $9 each at Kmart.
Both Jugs have the crack-ring seals and, in addition, foil seals.
