Not worth it, its not going to do anything unless you have modded the car to have higher compression or a forced induction setup (turbo/supercharger).

I switched to 89 Marathon over the summer, haven't noticed any power loss or mileage. But I also don't take this car to the track.

I always heard if your car isn’t setup for higher octane it actually does more harm by leaving more deposits since it burns slower. More timing and leaner mix will make better use of 93 over 86, but like others have said without high compression it would likely be a waste. Unless mixing works but I’d think you’d have a hard time ensuring the right amount, to up your existing octane value.

Yea you should use the fuel recommended for your car. For example using premium on a car tuned for regular won't do anything for you.

Race fuels tend to have low levels of lead. A bad thing for or cats.
