Hi all, so I know there's been some discussion on this topic before on here, but the forum search function rather unhelpfully tells me that "OAT" is a common term and hasn't been included in the search!
I am musing about the possible benefit of using OAT based coolant in my stag when it all goes back together. There's no risk of the mixing with blue and subsequent gunge problem because all of the components of the cooling system are completely stripped apart right now - including the heater matrix and are completely dry.
Some time ago, in one of those situations where perhaps a "measure twice, cut once" approach would have been better, I bought 15 or so litres of Evans power cool coolant, having been taken by the allure of lack of corrosion and not pressuring the cooling system. However, I've since gone cold on the idea having discovered it was quite thick, and the recent concerns aired on here - especially with an engine that can have hot spots towards the back of the heads.
Anyway, the Evans coolant can find a new home and I'm free to choose something else. Does anyone know whether the anti-corrosion properties of OAT coolant are superior to the blue type?
