The lowest octane that they have - usually only performance or luxury cars require the more expensive stuff.
87 octane gas. But who cares. It's a rental. Beat the hell out of it. That's what rental cars are for.
Your Toyota rental is neither a premium recommended or premium required automobile. Fueling up with anything other than the most inexpensive 87 gasoline you can find would simply be a waste of cash.
Use the lowest octane available. Typical commuter cars don't need premium fuel.
It just requires regular gas
I am in a rental while my other car is in the shop for a recall. I am in a 2014 Toyota Corolla LE. What type of fuel do those require?
