My Fiat 124 Spider Owners Handbook specifies 'Paraflu' as the approved engine coolant. However, a sticker on the coolant reservoir filler says FL22. Is there a difference? If so, which should I use? I have no previous knowledge of 'Paraflu'. My understanding is that FL22 is a Mazda coolant. Given that the Fiat 124 Spider is assembled in Japan by Mazda, is the FL22 sticker a misleading oversight by Mazda?
