Read the owners manual what does it say.......... then read the label of the anti freeze. Should be able to figure it out. and color does not mean a thing.as mentioned below

As the OAT is supposed to be less corrosive just how corrosive is ordinary anti freeze?
by how much will useing cheap anti freeze shorten the life of an engine?

it has to do with the plastics and rubber,nylon seals and parts in the cooling system and toxic properties of the old stuff. as a dog drinks it = dead dog

Oat anti-freeze is longer lasting then glycol based products and it's supposed to be less toxic to the environment. I've been reading bad things about oat and it's effects on certain plastic and rubber seals. This could explain why the later K engines inlet manifold gasket leaks but was unheard of on the k series until the late 90's? Who knows maybe that's why the KV6 thermostat O rings harden and leak coolant?? I don't use the stuff myself. Partly because i'm old and don't see what was wrong with the old glycol based coolant and i'v still got 25 odd gallons in my garage to get through!!

Glycol based antifreeze was designed with cast iron blocks in mind. OAT is slightly acidic (Organic Acid Technology) and was designed for Aluminium Blocks (but to be Ok with Iron) and also to be longer lasting. All together a better Antifreeze.
OAT coolants work differently than the older silicate based IAT coolants. Aluminium and ferrous metals form a surface-layer of corrosion in the presence of moisture, even with the little bit of moisture in the air. OAT coolants prevent this metal-oxide layer that protects the surface against this corrosion. Inherent with their design, the OAT coolants last longer than the older traditional IAT coolants. This category of antifreeze cannot be used in systems containing yellow metals.
The manufacturer can dye the product any colour they want. The colour is no guide to the actual type of antifreeze type and the label should be read before use.

Chance is the drive train will give up before my engine(touch wood)
96,000 ON LPG.
I have spent more on tyres in the last 6 years than on engine bits

apparently, the OAT coolant will degrade the Viton IMG and cause it to leak
(marvellous...well done Land Rover)
And silicon too iirc. Odd how the K series suffers from HG bonded seal failure!!
I may drain the oat out if mine and fill with bluecol.
Given the evidence it may be, long term, the more reliable option.
EDIT: obviously this will require a full flush to completely purge all oat from the system as they don't mix.

look on the small print and see if they have the same "G" code -
ie
G12
G12+
G30
G30
G48
G05
all are subtle variations on manufacturer approved specs.
If they are the same, yu are ok.

My MG ZS180 was suffering a leaky thermostat O ring when I bought it. I drained out the Oat coolant, changed the stat fitted new timing belts and a water pump then refilled with normal Blucol. This was 4 years ago, apart from changing the antifreeze twice in that time the car has been faultless loosing no water or oil in that time. He's not standard ether!? The last time I had her on the rollers she was making a healthy 210 bhp @ 6600rpm and I can say with conviction she doesn't show any signs of head gasket failure and i'm 100% confident she won't!!
Now that's interesting
i've just been reading up on the ethylene glycol or oat question and discovered that when my '99 FL left the production line it had EG in it.
this was due to not being recommended til june 2000.
some say that EG will severely pitt alu heads etc.... but i've yet to see any evidence of this.
the concensus seems to be that LR only recommend OAT cos it's 5 year long life, so doesn't need changing as often as EG (2 yrs) in the service schedule.
