Can't know that for sure now, but I wouldn't do that again if I were you.
You have to pay attention when you are using any type of race fuel.
Since you didn't use straight
115 octane leaded gas in your car, you are probably safe.
But if a 'SES' light pops up in the next few days...that's probably not a good sign.
FYI: Use the 100 or 104 octane UNLEADED Blue Turbo stuff if anything.
Stay away from off-road LEADED race gas
If not, it's going to cost you a large sum of money to repair the damage it causes.
