Make sure you have antifreeze, rather than pure water, in the cooling system. Pure water will crack the engine block and/or radiator when it freezes.

Technically, XZ is just a container that allows for different compression methods inside, much like the Matroska MKV video container. In practice, XZ is modified LZMA.

There is no perfect algorithm for every situation, so I'll attempt to summarize.

Gzip/zlib is best when speed and support are the primary concerns
Bzip2 was largely phased out and replaced by XZ (LZMA) a decade ago
XZ (LZMA) will likely give you the best compression, with high CPU and RAM usage
Zstd is... really good, and the numerous compression levels offer great flexibility

The chart below, which was sourced from this blog post, offers a nice visual comparison.
