For modern vehicles, most cars will call for 87, but check your owners manual for exact octane level. Higher octane just means it takes more compression to detonate, which is only important in specific applications like turbos and some higher end luxury cars. It’s important to prevent knocking.
Just don’t be like a buddy of mine and put 87 in a BMW that called for 91 and wonder why the engine was knocking.
