There isnt much option to choose from and i dont think we really need a chart for gasoline usage.
It could be different depending on where you are from and what grade of gasoline you have access to.
For Socal, i think Chevron and Shell will be my top choice. Theres a noticeable gain in throttle response with Shell gasoline but that could just be me. Not to mention we only have access to 91 Octane from regular gas pumps here
