Which Antifreeze?

[CHRISYD]

ive always used traditional "blue" antifreeze in all cars pre 1990. Bluecol usually but any known brand will do. Usually mixed about 40% anti freeze, 60% water. Change it and flush it every 2 or 3 years with no problems seen or heard!

This might get me murdered on here, but this blue, non-OAT, ethylene glycol-based coolant is in my Eclat:

Looks like perfectly good antifreeze

When I changed my anti-freeze I did so after taking advice from a (very) old school Lotus specialist based near the south coast. Having said that after reading the articles posted here it appears to me the only 100% risk free option is to stick with using the traditional ethylene glycol anti freeze.

After being swayed by the articles re OAT I've flushed my cooling system and refilled with good old 2 year Bluecol. It's a given that Bluecol is compatible with the engine so better safe than sorry.

I put Prestone in my Subaru at 50k miles, and when I blew it up at 100k and stripped
it down it was like new in all the waterways.

The condition of the big ends was less impressive, but unrelated.

I just bought some Prestone today for the Excel to put in. The guy at euro said it is really good stuff and can go in any vehicle.

I remember when choosing Antifreeze was simple...
I assume any non-oat stuff is OK for topping up but will have a look in Tesco. Bought my last antifreeze from the local car shop, Motoquip I think it is.
