sceh Posted February 10, 2021 Share Posted February 10, 2021 If I had a penny for every word written about antifreeze.. How come many companies ell antifreeze they guarantee is both compatible with all others and suitable for all cars? LR recommends an impossible to find product so why can't I use the universal stuff I find in the supermarket? LR4 diesel btw Quote Link to comment Share on other sites More sharing options...
Blanco Posted February 10, 2021 Share Posted February 10, 2021 The French don't use the term O.A.T. so I can sympathise ,.... translated it would be T.A.O. ..... I think you will find Leclerc sell pink coolant (usually ready mixed) which states it is approved for VW, if you translate the blurb you will find it is essentially O.A.T. I am sure that Norauto etc. keep 'pink' as well, just check what it says on the label Quote Link to comment Share on other sites More sharing options...
sceh Posted February 11, 2021 Author Share Posted February 11, 2021 So if it is OAT it is OK and there is nothing magic about the unobtainable Castrol SF? Quote Link to comment Share on other sites More sharing options...
Blanco Posted February 11, 2021 Share Posted February 11, 2021 It not magic, it is just stabilised using the organic acid to make it suitable for modern engines with fancy alloy components, including vw /bmw and many others Generally disco pink/orange sometimes electric green/yellow NOT blue.

taurion Posted February 12, 2021 Share Posted February 12, 2021 The 2nd page lists the approvals for Castrol SF: https://www.castrol.com/content/dam/castrol/country-sites/en_mm/myanmar/home/pdf/radicool-sf-premix.pdf, So any pink/yellow antifreeze that has one of these approvals will be the equivalent. Visit your nearest agricultural machinery dealer they will have a choice and probably nearer than Norauto or FeuVert. They should be able to find a data sheet for the product they sell that will list the approvals. Bon Courage Quote Link to comment Share on other sites More sharing options...
Alsace_rangie Posted February 15, 2021 Share Posted February 15, 2021 The Norauto pink (VW, GM etc. approval) does state O.A.T compatible on the label. I need to use this for my old Saab. Quote Link to comment Share on other sites More sharing options...
Arjan Posted February 15, 2021 Share Posted February 15, 2021 I've been using ready made coolant (-20 C or -30 C) from Roady for the past 20 years and all engines have survived. Can't be bothered with "anti-freeze" Quote Link to comment Share on other sites More sharing options...
BogMonster Posted February 16, 2021 Share Posted February 16, 2021 I don't have a D4 workshop manual but the earlier ones state the following for OAT: Anti-freeze solutions The overall anti-freeze concentration should not fall, by volume, below 50% to ensure that the anti-corrosion properties of the coolant are maintained. Anti-freeze concentrations greater than 60% are not recommended as cooling efficiency will be impaired. Use Havoline Extended Life Coolant (XLC), or any ethylene glycol based anti-freeze (containing no methanol) with only Organic Acid Technology (OAT) corrosion inhibitors, to protect the cooling system. CAUTION: No other anti-freeze should be used with Havoline Extended Life Coolant. Quote Link to comment Share on other sites More sharing options...
