STC50529 oat colour

Hippo · Jan 5, 2014

I have some genuine LR oats coolant STC50529 which has sat in the garage for about 4 years unopened. I found it yesterday and had a look and it's yellow. Is it still ok to use? Does it age or go off in any way and does anyone have any new STC50529 who could confirm it's colour?

Oat is Oat. Genuine Rover was yellow too

Oat is used to comply with some EU regulation not because the engine needs it!! I've good old Glycol coolant in my V6!!

Thanks. Would mine still be ok to use after being sat in the garage for 4 years? The LR oats for the Freelander was red for many years. Hence the question.

Hippo there is no one color for it. Different manufactures have different colors they use. all in marketing....... I got yellow in mine so i must use yellow and they search for the brand/ If blue, green or orange same thing. Just read the label all the same except color

If its the 5 year stuff, it will be ok for another year

That's the magic question. Do I get 5 years from the start of use? (yer I know I'm putting it in a v6 :doh

If it has been sealed there is no limit to shelf life

It will be fine.
It won`t be contaminated because it hasn`t been used.
Temperature or UV light has probably changed the colour.
Just get one of them cheap testers just to reasure yourself.

5 years from when you start using it

if it says on the package use before such and such or best before such and such then it has a shelf life so to say but if not use it

You might already know this, but you could compare a voltmeter test before and after changing the coolant.

that's interesting. Water isn't conductive but the impurities are. so measuring the voltage across the coolant to battery neg effectively measures the impurities in the cooling system. The more conductive, the higher the voltage, the greater the number of impurities like bits of metal...
