Would it be a problem to top up the existing oat coolant of other brand with this product? Any Compatibility issue??

No compatibility issues as far as I am aware

Can this go straight in a 2012 1.2 corsa ??

I have been putting this mixture into a 1.4 Corsa, which is earlier than 2012 and it seems ok - I did check online and it stated that this was about the best mixture for 1.4 Corsa - ready mixed - with regards the original question of the Corsa 1.2 2012, then I would suggest to make sure that it is compatible with the said Corsa - check online or check with a manufacturer.

Can this be used in a Vauxhall Corsa?

No sure. Models are printed on bottle or ask Halfords or local garage.

Perfect......

Well you don't need to pay the extortionate prices that some try to charge for similar products because this "universal" fluid is the same spec and just as effective, VERY happy with my purchase and the free next day delivery from Amazon for Prime members makes it such great value for money!!
