No, the best test would be to provide the oil so that someone doesn't pay for it. People tend to defend their purchases to validate their decisions. Not makeing a purchase neutralizes that. Psychology 101.
So if they pay for their current oil, you are saying they "tend to defend that purchase to validate their decisions" over free AMSOIL. So to be fair, they should pay for AMSOIL and run both for 25,000 miles. Apples to apples. 25,000 miles is a cakewalk for AMSOIL. Proven for 47 years.
I'd imagine if you went over 2x the amount of miles that the factory oil life indicator on the dash cluster states there would be warranty problems. Not worth it to me, and I'm quite the gambler
Warranty coverage is dependent on the cause of the failure. If the factory can prove the oil failed and caused the parts failure, then the part would not be covered by the warranty. However, if the factory can not prove the oil failed and caused the failure, then the part would be warranted. I ran AMSOIL for 5 times the recommended mileage stated in my motorhome manual and as stated by Mobil 1 and never caused a factory warranty issue and was still covered by the AMSOIL warranty. I had the oil analyzed and it was "fine for continued use".I'd imagine if you went over 2x the amount of miles that the factory oil life indicator on the dash cluster states there would be warranty problems.

Here is one place where you have a disconnect with reality. They (FCA) need to prove nothing to deny a warranty repair. They deny warranty claims all the time with no proof. If you stop spamming amsoil long enough to read some threads, you'll see what I mean.
Ok, I don't know how you would know there has not been a voided warranty over not changing oil according to schedule. I simply don't believe that and won't until I see evidence outside of Amsoil's own propaganda.
There can be more gray area than that. Good luck if you and the dealer or manufacturer disagree on it.
Put up the 6 quarts for an independent test by a forum member. Let them post a UOA, and if it is great, you'll more than make up for the cost in sales just to forum members. If not, then it's Spamsoilway marketing BS.
I couldn't be bothered to read any of Amsoils marketing, but was wondering if they require frequent oil sampling for their 25000 claims? Because like I stated earlier they did deny any warranty because it was not done.
Factory warranty covers against defects in workmanship or materials. If they deny warranty coverage for any reason, the manufacturer should put the reason and cause in writing. If they determine that the oil caused the failure, have them put that in writing. You can then present that to the oil manufacturer for a warranty claim. Since "They deny warranty claims all the time" I'd pick an oil with the best warranty.
If there was a voided warranty over not changing AMSOIL according to the factory schedule, I am sure it would be found on the internet somewhere. Or reported to BBB, FTC or other government or consumer agencies, especially since AMSOIL has promoted that for 47 years.
No required sampling unless you exceed 25,000 normal service miles, 15,000 severe service miles or 1 year on their Signature Series oil in or outside of factory warranty.
I'm not interested in giving away a product that has proven its claims for the past 47 years. I'm not interested in selling product here nor in becoming a vendor. I'm here to learn more about my Wrangler and provide my expertise in AMSOIL when asked or when I see misinformation.
1 gallon and 1 quart of AMSOIL Signature Series is available for under $48 wholesale. Every day. Under $1.90 per 1,000 miles for 25,000 miles.
