Mixing OAT Coolants

Tim_Burgess · 4th May 2011, 11:34

I have always used MG Rover OAT Coolant (the Orange stuff) on the odd occasions I've needed to top up the 75 or the MGF. However, I've run out and all I can get locally is Comma G30 (pink stuff)

Although it is OAT and compatible with the engine, according to the supplier, I'm dubious about mixing it with the existing coolant.

Anyone any thoughts on this?? Would it cause any damage?

As long as it's OAT I can't see any harm. I use the Vauxhall OAT which I mixed originally with some Halford's OAT already in the car.

Pink and Orange seem to have the same specification so I'm fairly sure they are compatible.

Thanks for the replies. I'm sure it will be OK but I'm a bit OCD about stuff like this, I don't like to mix different coolant or engine oil if I can avoid it.
