I can't find another HM oil on the market that meets the GF-4 spec. According to Mobil's HM website, the Xw-30 offerings aren't even 11 cST! Does Mobil know something that other suppliers don't? Is it all that Sodium they use in their dinos??
And look at those low flash points! This oil doesn't look any more exciting than the old plain-jane Mobil Clean dino SL product.
