Ford gauges for oil is not a gauge. Glorified idiot light. A lot of people did not understand fluctuating oil pressure,(rpm,temp ,etc) so ford put in a on off gauge. If you have a light or a gauge, put a mechanical gauge to verify pressure

It may actually be low oil pressure causing the light to come on. The next thing I wuld do is hook up a mechanical gauge to the oil pressure sending unit port and check oil pressure at a hot idle.

I had 300k on an F-150 and when that light took to flashing I should have done something. The pump went down and I seized it up for good so beware

Checking the oil pressure with an actual gage is a must.
Other than that , you may have some electrical gremlins causing alternator charging issues. Common things to look for or to have your mechanic look at - bad ground , bad fusiable link coming off battery. Short in wiring. If your oil pressure is truly good , bad electric problems can also cause the oil pressure lamp to flicker too.

Did u replace pcv valve yet?
Which motor? Not sure about this exact engine, but most modern engines no longer have a replaceable PCV valve.

Not real familiar with the F150's, but I know from a couple friends who own them, they don't seem to get the miles on them without a lot of issues, like the 3/4 and 1 tons. I will say that the Napa rebuilt lifetime warranty alternators are usually pretty good, I think every rig but my newest truck is sporting one right now. Never had to replace one at less than 150,000 miles after I installed it. . .UNLESS there was an electrical issue with the rig that was frying the alternator. If it isn't leaking oil but it is going through it, it pretty much has to be burning it. This could be a bad sign, on the other hand a lot of American made vehicles burn oil from the time they are new and get plenty of miles without issues, just make sure and check it regularly and don't run it too low. Otherwise you need to find out if the low oil pressure light is an electrical issue or an oil pressure issue, if it is just a malfunctioning electrical sensor, no big deal, if it is actually low pressure, get it fixed before it causes you to buy a new motor.
