No Quaker State on the shelf?

With what oil?

Ask yourself is there one reason other than EPA/CAFE standards Ford would recommend a 20W in your Coyote? If you are unable to find a reason 30W is your answer. My choice would be Quaker State 5W-40 for a good balance of value and protection at $22 5/qts delivered.

It's been a good 15 minutes since.

Go with #4 because I believe it is priced the best but find the 5W-30 IMO.

Drop the rear diff fluid at 2k as well. Grab a different rear diff cover that will allow for easy drains in the future without removing the cover. Diff cover and Better gasket Double check me on your application but I would do these. For engine oil, a quality 5W-30 with 5k intervals should do...

Old chrome wheels? If so especially GM products the bead needs to be smoothed out.

Did the multiple use of the hyphen or dash tip you off?

Any plans to use 5W-30 in the future?

Because this started right after the wheel/tire replacement I would look at the hub surfaces as I mentioned prior. You could check for wheel run out on the truck and if so that could be the issue. This will show a surface to surface issue while installed. Raise truck and secure a plastic pry...

Costco AGM.

Same here, bought roughly a month ago and June 5 2025.

Yet they will also install start/stop equipment or DOD/AFM systems which reduce reliability, increase manufacturings costs and increase warranty costs to help maintain CAFE/EPA compliance. My opinion is the recommended oil is a part of compliance, not what GM would ultimately recommend.

Love the dealership scare tactics to build service income. The service center is the cash cow of the operation afterall. Post #14 is the answer IMO.
