theres blue, pink and green what is recommended for an E30 and what is the difference between the colours.

Green iirc - I'm sure the BMW antifreeze I used was green. It's not just antifreeze, it's also a corrosion inhibitor.

There has been some really heated debate about this subject in the past.

I use blue.

I use Comma G48 thats the green one that jmc330i mentoned.

But really up to you i suppose pink or blue is ok for general use but do not mix them.

Red is more modern stuff, green or blue is the stuff. I too use the comma blue (bottle label is green)

Is it fine to mix 2 different BLUE brands of antifreeze when topping up the levels?

Shouldn't pose an issue as long as they're both blue right?

Good solid blue glycol based coolant for all BMWs pre 95.
