2020 MINI Cooper recommended gasoline?
For my recently leased Mini Cooper 2-door hardtop, I know the dealership
first filled it with premium gasoline. I looked at the manual and it says mid-
range to premium is okay.
My parents say that filling it with regular gas is also fine too, since we're only
leasing it and I'm still a student (affordability).
Would there be serious issues if I start filling the car with regular gas instead
of what's recommended? (Given that the lease term is 3 years)
Thank you.
