87 would void the warranty and almost certainly cause engine damage.

I guess I'm screwed, since in the south we only have 91. However, 91 is perfectly fine for the car. Will not cause issues, will not cause less power. It's still a very high octane fuel.
87 is not gonna void the warranty, and honestly doubt would cause any damage. Remember, cars are a lot smarter than you think.
