Their GF-3 oils had a 12 Tbn and a lot of Ca. They were clearly long drain oils and held up as good or better than Amsoil ASL/ATM IMO.
Amsoil a few years ago had oxidation issues with their oils and was using what appeared to be old chemistry. For example, when Mobil started using over based Ca and Boron, Amsoil was still using Mg, which is hardly found anymore in any modern oil. Once GF-4 came around, Amsoil ASL/ATM looked identical on paper to M1. (base oils excluded). Don't be fooled in thinking Amsoil doesn't cut costs. Amatuzio has admitted to playing hardball with additive suppliers.
Mobil has just butchered their lineup and now offer too many different oils. I would have rather them just make 1 Mobil 1 that is good for 15k/1yr when out of warranty. Two M1's says they cut costs somewhere.
Not all Amsoil's oils are better than Mobil 1 too. SSO/ASM are but some of the others like AFL/AFO etc. are nothing to brag about IMO.
SSO is their top of the line oil and is most likely using additives that are about a year or so away from being found in OTC oils.
Every oil company has it's woes and Amsoil is no exception. But this is a company that has always guaranteed their oils for the mileage on the bottle as printed without trying to get out of it with fancy wording.
I could care less whats in a an oil in terms of base-stock or additives. I just care how well the real world performance is and if the company stands behind their products in the event that they need to pay out.
And to me M1 doesn't seem to be confident enough in their product as Amsoil is in backing it up by a Mileage guarantee. That's all I'm saying.
I never said one product was better than the other and I have always said M1 is a darn good product and I have used it in the past with great results.
When everyone else catches up to SSO, then SSO will reformulate as they do with all their oils to become the very best if not better than everyone else as they are always striving to be and can afford to because they aren't spending ridiculous sums of money on some IMO, stupid API certification that doesn't mean much anyways when a company is willing to back their product with a mileage guarantee and pays out if it doesn't work or causes a failure.
So again I raise the question... What is the problem?
