Werner, I'm sure you can find 1000 or 1500 in the EU, but you must search for it.
Gold standard Mobil SHC 636 which is ISO 680 has a pour point of -39C, and even Mobil SHC 639 which is ISO 1000 has a pour point of -33C. There's nothing stopping you doing that winter trip to the Kremlin that you've always wanted to do. See:
