Looking to put Amsoil in my new 2019 F150 3.5 EB like the rest of my cars.
Signature Series 5W-30 Synthetic Motor Oil with an Amsoil EAO17 oil filter.

But since their signature series oil is not certified by the API, I heard Ford could potentially void your powertrain warranty.
Wondering if anyone else is concerned about that or had issues in the past.
I know Amsoil has a few oils that have the API starburst but I really wanted to use their best oil.

Ford would have to prove that the oil caused a failure to void your warranty. But if you believe in the Amsoil hype you shouldn't have to worry about the oil causing a failure.

Don't tell them.

I figured if they see an Amsoil filter they may ask for the receipt for oil that I purchased?
Typically you're suppose to show the receipts for your oil changes, not sure what you do if you do your own oil changes though.
Show the receipt for oil purchased? Not idea.

If the failure is engine related they only have to prove that you didn’t use the oil they specified in the manual. This whole burden of proof on the manufacturer is false.

Do you have any supporting info?
Because in 1975 Congress enacted the federal Magnuson-Moss Act to regulate written consumer product warranties. Which does make the manufacture proof a failure.

RL1990

The Act you are quoting says unless the manufacturer explicitly specified what is and isn’t covered by warranty. Ford didn’t print the warranty and owners manual for nothing.

These documents are like a contract between the owner and Ford. If Ford failed to say what oil to use you would be OK. But Ford has given you specific oil requirements. Failing to use the oil specified in the manual would give a Ford an opportunity to deny warranty coverage.

Most common denial reason by many manufacturers is the owner didn’t follow the maintenance schedule.

Why not just use the recommended oil?

If not, just be prepared to have your engine warranty voided. Lying to a dealer is wrong.

Ooh, I need some popcorn for this one!

So, here's how it's going to go down in the real world. Let's say you pop a motor. That's a big chunk of coin, and Ford is going to do some amount of looking into it. If they find indications that the damage was caused by oil issues, they're going to want you to produce documentation of your oil changes. If they feel the Amsoil caused your issue, since the oil isn't *tested* (not engineered to) whatever standard, then they'll tell you to **** up a rope. Yeah, maybe with enough legal work (and that's a big maybe), you'll be able to force Ford to cover it. But the whole time, your truck is out of service and you have no wheels. Oh, and you might hire an attorney for a few hours a week... Ford has dozens of lawyers on staff full time. Getting sued is nothing to them, it happens all the time, just a part of business.

Or, you could skip the Scamsoil and install any of the exceptional oils out there (M1, M1EP, PUP, etc.) that *do* carry the proper API and Ford certifications. And save several dollars a quart.

By the way, when was the last time you heard of any reasonably modern motor coming apart due to oil issues, assuming that engine was properly maintained with reasonably timed oil changes and any oil that meets Ford/API requirements?
