Which says to me the original ones won't pass. Why pay for a new forumlation, making it, new packaging/labelling etc etc when you can just pay a small fee to certify what exists already?
This again? If AMSOIL Signature Series was a bad oil it wouldn't have proven to provide EXCELLENT (extended drain, severe service) service life in real world vehicles as well as a bunch of great used oil analysis. Certifications are nice and all, and prevent bottom of the barrel junk oil from going into modern high-tech engines, but when it comes to a premium product like AMSOIL, real world results are more important than paying a licensing fee.
Besides, I was under the impression AMSOIL Signature Series ONLY fails Dexos1Gen2 requirements due to a slightly higher percentage of sulfated ash than they allow, but doesn't fail the performance aspect of it? Am I wrong?
And even their OE series that's like what 1/2 to 2/3 the price of Signature Series, has excellent used oil analysis on here that are on par with other products at similar price ranges. I work at an auto parts store and people frequently pay full price on their favorite brand of oil even if it's not on sale. Castrol Edge, Mobil 1, PP, Valvoline Synthetic, is like what, $44/5qt regular price? That's like $9 quart, comparable to AMSOIL Signature Series, and AMSOIL OE is actually cheaper than that!
Where did I say it wasn't any good? I just said it wouldn't pass certification.
