Coolant for 1985 Mercedes 300 TD

Can I use any contemporary, branded, high quality coolant in my car or does this wonderful vehicle require the MB stuff at $25 a bottle and a visit to the smarmy parts department manager at my local agency?

Prestone’s web site states that their ‘extended life’ anti-freeze is good for all makes and models cars. I would do a flush, then use the Prestone, as they instruct.
