Had my oil changed yesterday at 1,359 miles with Valvoline Full Synthetic Max Life 5W20 The recommended next change is at 4.356 or 2/17/22. 3,000 miles seems short to me. I'm thinking 5,000 mi. Comments

I’m in SanAntonio
5000 is fine and maybe overkill.
id move up to 5-30 tho.
I do my changes on all the cars at 5000
a couple of these cars may only get 1000/yr
My 5.0 is about to roll over to 5k on this change, and the oil is still pretty clean, and the oil life meter is at 68% remaining.
To be fair, this truck sees virtually no city driving. All rural hiway stuff.

For your 2021 F150 V8, the correct oil weight is 5W30. I wouldn't leave 5W20 in there very long...

Cooler weather I go with 20W, hot weather 30W. I typically change my new motor oils after 500 miles to get the break-in oil out then again after the next 500 miles then go to the regular intervals. My new truck was driven 300 miles highway to get it to my dealership. With the top/Start crap feature which I turn off after starting my truck using 30W makes no sense.

What possible reason would you run an oil weight not meeting Mfg spec? 5-30 will give a 20Wt when needed, it won't give 30wt protection if needed.

MFG specs are nothing more than "recomendations" not mandatory warranty busting rules of operation. Show me data that states 20W offers less protection and against what and at what temperatures? I ran 20W in my Ram Hemi for 14 years and in my 5.0 Stang for three years in the cool months and 30W in the hot months. In the upper states where the temps are at sub zero they run 5W oils in the cold months. No worrries here

Running 5W in colder months isn’t exactly a normal thing in the northern states. I’ve never run anything but mfg spec nor would any dealer install otherwise either. Not saying it couldn’t be done, but that’s not exactly common practice just because it gets cold where you live.

I lived there and worked there and 5, and 10W are used in the cold months

I'll change mine at 1500 miles and then at 5000 miles or one year which ever comes first, with Mobil 1 full synthetic. This has always worked well for me in the past.
