I have a 2019 Dodge Challenger Redeye I’ve found that a little octane booster mixed in with 91 octane gas seems to improve engine performance. Will Boostane professional additive damage my engine or catalytic converters. 91 octane is the best we have in California

What does the can say or the manufacturer? So NO stations carry 93 in all of CA? If the engineers say they make the power with 91 pump gas, that's good enough for me!

Apparently, octane booster is bad on the plugs.

And O2 sensors as well as leaving deposits on valves too.

Have seen pics of plugs from an engine that was fed Boostane and the plugs had a red deposit.

Other surfaces exposed to combustion/exhaust gases also were reported to have this same red deposit.

Boostane might be ok in a pinch say if one was going to the track and there was no "racing" fuel available but I'd not run an octane booster on regular basis.

And "seems to improve engine performance" is pretty thin justification for using Boostane (or any octane booster) on a regular basis.
