Amsoil Signature Series vs. Heavy Duty

You've been here since 2015 and you are asking this? Those are silly questions, facetious or disingenuous perhaps. You even imply Amsoil doesn't test.

Amsoil simply knows what the specifications are, tests above and beyond the specs. It's not that difficult to understand.

Certification really doesn't matter before warranty expires, if the oil meets the specifications. Plenty of the threads on this as well.
But think of all the Rotella skeptic 5w-40 Ford PSD customers Amsoil would have if they would submit for the certification they already know they would (hypothetically) pass. This is a business opportunity for them.

It's possible. But probably not. I've been an Amsoil Dealer for 25+ years, no one has ever asked for any auto oil specification. Never once. The above average consumer even - in the USA doesn't know or care about car manufacturer's oil specifications. Oh some might see API ratings, many will look at SAE viscosity grading. It's a bit sad, frankly in some ways I do wish GQ Public would educate.

I'm not the only person that looks past the grade designation. People that come to you have already committed to buying an amsoil-reccomended-amsoil product, regardless of certifications, because marketed as better has already sold them. Those that care about a cert already know the answer and doesn't bother to call.

"You are not required to use an oil from Ford's approved oil list, and Ford cannot deny warranty for using an oil that isn't on their approved oil list. The oil only needs to carry the correct Ford specification (WSS-M2C171-F1) and meet the correct viscosity requirements. AMSOIL will never be on a Ford approved oil list."

Well that's the dumbest response I've ever seen. So you are not required to use an oil from Ford's approved list, it just has to be an oil that carries their specification (which by default means it's on their approved list)? Um, ok....

I guess I will second guess this. Maybe I'll just keep driving around town looking for oil. Usually T6 shelves are bare, or maybe there's one gallon and that's it. So then I have to either buy another brand and mix, or drive to another store, and then the process continues. It gets annoying. I could order online, but usually it's more expensive. Wife and I don't shop at Sam's anymore...too far to drive and they have membership fees which are high.

I do think the response (if true) could have been better worded, but also you are misunderstanding their meaning of "carrying a specification." In Amsoil's case (I can't speak for HPL, Redline, Schaeffer's and others) it means they have tested the oil to the physical requirements of said specification and it exceeds that specification or they wouldn't put the spec on the bottle or website.

You'll find lots of products that claim or recommend for a specification, which is what the boutiques do, which makes them no different in that regard than universal fluids that claim many specifications but certify to none: Valvoline Maxlife. It's different to certify to the specification and be on the list (Valvoline ATF+4, Valvoline Dex VI.) Granted, some specifications are no longer actively managed (Dex III) so they become fair game in their old age. Triax for example claims specifications and has been found to not meet them...

Amsoil (and their dealer reps) seem to imply they are F1 approved because of Amsoil's recommendation in lieu of being on the list. I guess we take Amsoil at their word for it, even if they don't actually publish all that it entails. "Here are all the requirements for spec A, B, and C, and the independent test results showing we meet/exceed/reconcile all of them."

Do you have a tractor supply nearby? TSC you can order online for pickup. They'll also pricematch and they frequently have rotating specials on Shell's Rotellas. Lately Amazon even has T6 at walmart prices. Advance and OReilly will pricematch Walmart's in-store price and mine generally have stock and can call ahead if need be.

Discounted Sams plus membership purchased on groupon for $50 a year and they deliver...

No you're not required to do so. What's required for the warranty is to use an oil that does not cause damage. Damage is the predicate for warranty.

The Amsoil product isn't going to cause damage.
