I'm not asking about the test that indicates the HTHS. How does Joe Consumer know what it is? I see people here give the HTHS of a specific weight/brand. I just went to the Mobil1 and Pennzoil sites and on their PDS's they didn't list it.
Is there a list here on BITOG?
If it matters, I'm looking specifically for 30 grades, either 5w or 10w for my cars.
