I’m about to change the thermostat in my Sigma engined 7 and renew the antifreeze.
Premier Power did some work on the engine last year and I have blue antifreeze in to protect the new Radtec radiator. My thinking was I’ll change like for like, but standard Bluecol is no longer readily available. This was recommended to me Bluecol OE48 Hybrid Organic Acid Technology as the replacement. I’m wondering what’s the difference to OAT?
As I use my car throughout winter, only being parked up if there is salt on the roads, could I go back to the OAT antifreeze Caterham recommend?
