Amsoil is famous, has been for years, at saying a lawyerly "recommended for ..." and deceptive phrasing to make some casual readers think it is really certified when its not. They do that with dexos and avoid paying any fees to GM because they are not approved for dexos. Mustang spec too.

On the other hand, many people trust Amsoil. Period. I do think they generally produce great products. So we're not sure, yet some trust Amsoil's word on it.

Ahha, I see. Well, I'm not sure where he got that information from, the Amsoil website itself doesn't say that.

Yes it does say "recommended for..mustang" http://www.amsoil.com/shop/by-product/mo.../?code=AMRQT-EA

Notice Amsoil does not make any other spec claims (besides the basic SN) other than the specific Mustang one. Amsoil has targeted this oil at Mustang owners specifically. I heard Amsoil works with Lubrizol, so I guess they likely make very good oil. Trust them.

Some counselors could be reasonably certain Ford would insist upon consumables of "certified certainty" should our OP's lump die yet again.
Officially.

I looked all over and never saw the word "meets" anywhere connected to the specification, and that is the term being thrown around in this discussion.

And your recommendation isn't exactly the most assuring.

I had Blackstone do an oil analysis and compared it to the full synthetic Blackstone results. That's how.
As far as Ford doing a viscosity test, if the dealer did the service do you really think they would tell you they screwed up ?

How did you find out? Viscosity test, or you looked in there while they were working on it?

I never said Ford would or did do any viscosity test. That would be what you would do.

Keep in mind your Blackstone UOA might show shearing to a 20-grade on viscosity, so you would have to compare the specific additive elemental ppm's to say for sure if 5w20 vs. 5w30 was substituted. A UOA can't tell what basestocks (Group III vs. II) are being used. You'd need to look a levels of moly, calcium, maybe phosphorous, boron and compare to VOA's of the oil you're comparing. Some people have merely looked into the service bay and noticed the wrong oil being put in.

Don't waste your money on Amsoil, it's not worth the price IMHO because the others do the job just as good if not better and can be easily obtained. Try going into any retail store and buying Amsoil, won't happen! I'm sure they're good oils, but the pyramid scheme sales tactics they use are outdated and annoying, it's 2017, it's time they joined the rest of us. Whatever you use, just make sure it meets the right specs. Of all those listed, my picks would be Castrol 5W-50 or Platinum 10W-60.

The local BMW dealer would have the Shell product in a BMW bottle.

Castrol TWS is also available on Amazon at the $10/liter mark.

The Castrol has an amazing pedigree.

I was corrected earlier in the thread regarding Amsoil specs.

I did find some Motorcraft 5w-50 for $9.58 a quart (shipped). However, it only comes in cases of 12, so there's that. It was cheaper than what I could find Amsoil 5w-50 for. The reality for me is that I can't find locally stocked 50 weight oils and have to resort to either dealership oil change prices or buying online.

Q: How does AMSOIL INC. ensure that its products meet or exceed the minimum specifications of the tests required for licensing?

Answer: First, AMSOIL INC. works closely with major additive companies to select the top-performing, and usually most expensive, passenger car and heavy-duty diesel motor oil additives. These additives have already passed all of the licensing requirements in a petroleum- or synthetic-based formulation. Then, AMSOIL works with the additive company to maximize the amount of additive used and to boost the additive package in selected performance areas to achieve an optimum performing additive package for the intended application. This is unlike many other oil companies that, because additives are expensive, use the minimum amount of the least expensive additives required to meet the minimum API requirements.

Amsoil AMR PC price is $8.60/qt, case price $98.25 makes it $8.19/qt.

As noted, use of AMR 5W-50 will NOT void your warranty. Likely using a non specified viscosity will.

After membership cost, taxes and shipping; it wouldn't be a better price. Not saying anything about Amsoil's product though.

It does state in the Shelby GT350 supplement:

"Your engine has been designed to use engine oil that meets Ford specification or an
equivalent engine oil of the recommended viscosity grade that displays the API
Certification Mark for gasoline engines. Do not use supplemental engine oil additives,
cleaners or other engine treatments. They are unnecessary and could lead to engine
damage that is not covered by Ford warranty."

You are going to pay taxes regardless. PC cost is covered. Shipping will be about $12.

That's part of it, the rest says:

Quote:
Use Motorcraft SAE 5W-50 full synthetic or an equivalent SAE 5W-50 full synthetic oil meeting Ford specification WSS-M2C931-B.

That would have more meaning if Amsoil actually used the term "meets" or "exceeds" in the literature. As it stands now it only says "recommended". That isn't the same. ExxonMobil often uses "According to ExxonMobil is of the following quality level" which clearly states that it does not actually carry the certification, but that in their opinion it is equivalent (as opposed to stating "has the following builder approvals").

I can see "recommending" an oil for some applications, but not for meeting a specific specification.

Honestly I think the MC oil is absolutely fine and you will not be doing any good to switch to something different. Your engine did NOT fail because of oil.

These things just happen...its why we have warranties. I once saw a brand new 98 suburban with a 5.7 being backed off the semi and the dealership throw a rod..it had 4 miles on the clock!


FWIW I had a 95 Mustang with a GT40 crate motor at 10.5-1 with a 12b blower (active oil feed) on it. It had over 500RHP and turned the quarter in the low 11s on street tires. I ran conventional oil in it for years and beat the snot out of it. UOAs were always stellar at the annual oil change (less than 5k) and the motor hadn't lost any compression when it was check by the fella who purchased it.

Here...Ford has made it very easy for you. Follow this and worry about your tires or something else.

 

[Pablo]

Ford WSS-M2C931 spec requires the product to meet API SN, be full synthetic, 5W-50, and just a touch better deposit control than API SN (it’s still an easy one pass though). AMR crushes the requirements, and is fully suitable for use in Mustangs calling for the spec. In fact, those applications are the sole purpose that AMR was designed for.

The words "any", "always" and "never" usually aren't.

I have found Amsoil sold at some surprising retail stores.
