So ive had my 2015 frs for 2 years, (some background) i recently started putting A LOTTT of miles on it like 200 daily 5 days a week, Car is running great everything good, temp doesn’t fluctuate it’s a 2 hour drive and it usually ends off at like 35-50% on the temp gauge. I just became worried because I saw another brz with blue coolant. So I searched it up online and it says gt86/frs/brz should run blue coolant. Well my car has been running red coolant for 2 years and levels are always fine, temp is good, car itself is good. Should i worry bout it and flush it to put the correct (blue) coolant? Or it don’t matter ?
