Shannow,
Which oil is Amsoil claiming to be A3/B4 with HTHS of 3.4? Looks like the 0W40 being discussed has HTHS of 3.9, and their Euro spec oils range from 3.6 to 3.8?

Great question. I always took the "recommended for" wording to mean "Amsoil thinks we might pass all the tests" without actually having run all the expensive tests Mobil1, Castrol, and Pennzoil do.
Have got in quite a few arguments on here over their weasel words.
(Note here, that I am not accusing Amsoil of not doing any testing which is the strawman that's flashed up when their testing is questioned).
Amsoil make recommendation, when their oils are clearly not compliant...obviously, and this is the most simple an oil with an HTHS of 3.4 ISN'T an A3/B4, in spite of "recommended for" wording.
Their testing allegedly takes the raft of industry tests, then applies the worst of the tests, stating that if it meets the worst, then a "lesser" test is an auto pass when making their recommendations, or "meets or exceeds"...we are still waiting in some other threads for what these "harder" tests are, when they are making statements.
Personally I'd be interested how they do sequence IVA when claiming API specs for starters (I have my suspicions).
