I was home visiting my family this weekend and i was going to use some Redline SL1 on my drive home, instead my dad accidentally added half a bottle of some MMT based octane booster VP racing fuels into my 2007 Cayman S that he had leftover. Is there any short term or LT harm to my car? Should I use the redline on the next tank? Will this help clean out the MMT?

The MMT is an octane booster and shouldn't be any cause for concern. The SL1 is a cleaning agent and not an octane booster. Long story, short: No big deal, just keep driving and use the SL1 if you want to clean things up.
