That is the MSDS, I read that as half group 1 and half group 3, which is no big deal. Does anybody who actually knows how to read an MSDS see something different?
Ah...thanks velociracer. The one I found must have been old. Yeah not the best but the HTHS On the 10w40 isn't bad. I may try that next in my BMW, for $2.50 can't beat it with a stick. BUT it only says SL for the 10w40. Wonder if they updated the additives anyway to be same as this 5w30? Is Butler still doing the free UOA if you send a bottle?
The other HTHS I should have expected. Typical of an API oil. Not much variances to be found.
