My first was at 1,800mi, then 5,800. I just moved up to 5w30 @ 10,800 miles and these engines most definitely should be running it.

While it seems every credible mechanic suggest's moving to 5w30. I haven't heard one suggest 5w40 to date.
Yet I'm seeing more mustang owners and a few f150 guys say 5w40 is the cure all, if you have the batch of 18's with the knock.

I don't have enough proof to make that move yet. I also didn't hear any noise till it was time for an oil change and after moving to 5w30, it runs like my 14 did. Quiet and solid.

I change mine about every 10K or when the change indicator says it's time. Any more than that seems like money I do not need to spend.

Changed mine at 1,000 miles and at about every 4k miles after that. Sometimes sooner. Takes me a while to put 4k miles on a vehicle so doesn't seem like I change it much

I do mine at 3K for first (assuming dino oil from factory) and then every 5K after that.

2019 3.0L Turbo Diesel, oil and filter changed at 580 mils. Pulled filter apart, absolutely NO contamination of filings present. Next change at 2K. Changed it using the Ford filter and Ford F150 super special diesel oil....ha ha....but anyway, runs great....
