3) The claims of increased MPGs and more power are not demonstrated across all product lines.
4) Extended drain intervals are not as they claim since you need to add 1-2 qts of new fluid. From Amzoil: Note: 2007-2010 Dodge**, Ford** and GM** turbodiesel pickups are also not recommended for extended drain intervals when using DHD.
AMSOIL Heavy-Duty Synthetic Diesel Oil is recommended for the drain intervals stated by the original equipment manufacturer (OEM).
5) No Amzoil rep will ever stand up for the product claims. If you want to face a real challenge with your product PM me.
6) Did I mention if it was REALLY that good we all would already be using it. See the above.

As as noted earlier in this thread, everyone has their own opinion and bias on this topic. Thank you for stating yours.
as for increased mpg, most vehicles I've added amsoil to did see mileage gains. The vehicles I didn't see mileage gain were heavily geared (like my wheeler with 5.33 gears). That is an off-road vehicle only and the mileage gains were not noted when I'd run it on the street.
as for the drain intervals, this was impacted by the emissions systems on these truck. The fuel dilution issues caused significant issues with the truck among all oils, which is why all oil manufactures recommended early changes.
i am a dealer and I do stand by the product. I don't try and grow this business as I have other options to follow. That said, I do recommend this product 100%. Sounds to me like you had a bad experience and resent that. Those are things that can't be avoided. Sorry the rep at the time wasn't able to satisfy you.
i know amsoil is a good product, which is why I am still a user. I also fully recommended it. The op asked people opinions on it, so we shared, as did you. Thanks for sharing. Despite your experience, I have zero issues using or recommending the product.

This is the funny part: If the AMSOIL lubricant is defective in materials, design and workmanship, AMSOIL will (1) replace the defective lubricant; and (2) at the option and cost of AMSOIL, repair or replace components damaged by the defective AMSOIL lubricant.
It's their OPTION to repair/replace
.....LOLOf course the remainder of the "warranty" I want to post is a tad much to post here but it's an interesting read. Could it happen sure, MAYBE your motor will get paid for but hope you can let it sit till the check comes in.

I never said it was different. Last I recall no sales person from Mobil 1 or Shell uses it as a selling point.......unlike Amzoil.
That's my point....it is the SAME as all others. Nothing special.

Not sure why you are so anti Amsoil. Sounds like you had a bad experience with it. Just to be clear the quote in bold doesn't really have much to do with our discussion here. Amsoil doesn't even list the DHD (5w30 diesel oil) as recommended oil for any '07-10 Powerstroke, Cummins or Duramax. Opinions on oil are quite varied. I have had great luck with Amsoil and will say this much. If you were my customer and had issues with Amsoil I would try my best to find a solution. Just my $.02
I was demonstrating the pull back on extended drain intervals. I picked two of their "diesel" oils at random. Nothing here (AMSOIL Signature Series Max-Duty Synthetic Diesel Oil 5W-30)disqualifies use of this oil, just their little quick oil selector tool doesn't pull it up. In the end I guess we have established it's more expensive, hard to get, doesn't always improve MPGs, doesn't allow for extended drain intervals, AND has just the same warranty as any other company out there. SO.....why is it so much better? The name? The bottle? The buying experience? I guess I'm missing it......Thanks for allowing me the opportunity to defend my simple original opinion. I didn't expect to get beat up about it since all the facts are there in plain sight.

I guess there is an echo in here...repeating what I posted from the Amzoil site...guess they don't keep their info up to date.. I was demonstrating the pull back on extended drain intervals. I picked two of their "diesel" oils at random. Nothing here (AMSOIL Signature Series Max-Duty Synthetic Diesel Oil 5W-30)disqualifies use of this oil, just their little quick oil selector tool doesn't pull it up.

Point and case, this is why I stated people have their own strong opinions both ways.

New diesel owner here. I'm at the 3000 mile mark & want to get my first oil change done for my 2017 F350 PS. I'm an Amsoil user for my other engines & will be using it in my new truck. My question is while I prefer to use full synthetic motor oil should I wait until the second oil change to use a synthetic oil? Do these come from the factory with regular oil, a blend or full synthetic? Thanks

You should have the Motorcraft 10w30 in your 6.7, I would think...unless someone who knows more than I can definitively answer and confirm/deny that.
They make a 0w40 and a 5w40 full synthetic diesel oil and also make dino 10w30, 15w40 and 30w. But the recommended normal use weight is the 10w30. You can find that stuff here.
They also have a list of approved brands of oil Meeting Ford WSS-M2C171-F1 spec there.

Using a higher grade engine oil such as Amsoil full synthetic will not necessarily be better for the engine in your truck. If you continue to use the factory recommended engine oil along with proper maintenance you will most like never realize any difference. Amsoil full synthetic engine oil meets or exceeded the Ford Motorcraft specifications. The only real way of find out the difference or benefits if any by using Amsoil or any brand of engine oil is to send a used engine oil sample to places like Blackstone Laboratories to have it analyzed. If the results of the lab test has convinced you that you should change then go for it. Otherwise you will only continue to read more information like this on the internet.

Folks, I posted the list of oil that meets Fords WSS-M2C171-F1 standard here - https://www.ford-trucks.com/forums/1...ngine-oil.html - someone else found one that is newer than mine.
The other interesting thing I recently learned is that oil produced prior to 2016 and has only the CJ-4 in the "API Circle" is "ok". I also posted in the thread above a letter from Ford around the 2016 CJ-4 being "ok"

As I remember the effect of the oil that doesn't meet Ford's requirements is long range, probably not until over 150,000 miles before it is significant. I may be wrong about that. I think that when we think of an engine "failure," we are envisioning a failure like we see at the NASCAR races. But I think what we will see is a gradual degradation, therefore not causing anyone's warranty to kick in. And...if we trade in early, we may not see a problem at all.
I understand peoples' loyalty to brands. I have those I like too, but I think that most oils meet basic API standards and are probably just as good as any others' oils. Especially if you change oil often. Now, I'm old school, really old school, so I'm staying with the 5,000 mile oil change, and I'm staying with Motorcraft.
As to fuel mileage: I guess I'm the only one who gets 9.5 to 10.5 mpg in town. Everyone else seems to be making fuel. Highway mileage? I only get on the highway with a 5th wheel attached. Then I get 9.5 to 11.0 mpg. I don't think a different brand of oil is going to change that.

Gotta love oil threads.
We all have different duty cycles too. My 2015 truck has 170,xxx on it and by the end of next week it will be 171,xxx. I change the oil when the truck dings at me, which is around 7500 miles, which is about every 5 weeks. For me, using a high priced boutique oil would be stupid. Just using shell T-6 costs me about $70/month, fancy stuff would be $200 bi-monthly? No thanks.
Fuel and oil for some people is a real expense on a weekly basis. Even if I changed oil at 15,000 mile intervals I'd be buying 18 gallons/year. I use the cheapest 5w-40 I can find which is valvoline at present. I used T-6 since 2011 and never has any reason to change.
