Not a thick vs thin debate, just a simple question.
I have seen a number of XW-30 oils with an HT/HS of around 3.0, +/1 a tenth or two percent. Red Line, and I am told others, has a 5W-20 oil with an HT/HS of 3.0. Will a 20wt with that number offer the same protection as a 30wt with a similar HT/HS?
