Context is everything. The oil drain plug is on the oil pan. An oil pan looks a lot different than a radiator.

I've seen mention of a plastic oil drain plug on the 2.7 and 3.5 ecoboosts, but to my knowledge the 5.0 has good old metal.

I'd recommend that you replace it with a Fumoto valve when you do your oil change.

Yea I know. The second pic looks like a rad to me.

Agree, if that's original, I would have done it long ago.

If you’re referring to the truck in your avatar, how did you manage to pay 50k for an XLT?

It’s been covered. Turn the yellow plug a quarter turn, but be careful. Oil comes out fast.

Those things scare me. Just like the junky ones on my garden tractor.

I see both of the following as being true.

In a previous vehicle I tested synthetic Amsoil and dino oils (Valvoline white bottle or VWB and SuperTech). The VWB and ST were fine at 5000 miles but close to being depleted. The Amsoil went 10000 miles and analysis said it was still good to go, and I ran it as far as 12000 miles (still good to go further but I'd reached the end of my comfort zone).

In the current F150 I've just completed a run of 9100 miles with Schaeffer 9000 synthetic. IOLM said the oil had 15% life remaining. Oil analysis showed the oil was in great condition and could likely go at least another 2-3000 miles. The oil run included mostly high altitude (5000'), as well as a 1400 mile, 5000# trailer tow. I'm currently running Amsoil and will have that tested at 9100 miles to compare.


Again, agreed. Mine clicks over 1% almost religiously every 100 miles. Doesn't matter if I'm on the highway, around town or towing. It also counts down if it's parked for a couple of weeks; IMO it is calibrated for a change at
6 months/10000 miles. Perhaps really severe usage would reduce that; but I don't know that for sure.


Each vehicle may be different, depending on engine, driving habits and oil used. A safe interval might be 5000 for some, or 12000 for others. Without a UOA (Used Oil Analysis) it's just guesswork. My advice is to pick the oil you want to use, and get a couple of analyses done to nail down when your oil gets depleted. Change it at that interval.

I went to a local dealer last week to get "The Works". After returning home I checked my oil because I am a mechanical person and do not really like others working on my equipment. The oil on the dipstick looked as dirty as when I took it in. I could not tell the difference. The truck had 8500 miles and this was the first change. The washer fluid also was not topped off. Before going in the front tires each had 2 lbs more air than the rear and it was the same after I picked it up. I contacted the dealer and they went out of their way to see that I was satisfied. They performed the services "again" and provided me a coupon for my next "works service" for free. After arriving home I checked my oil once again. This time it was the clean honey looking appearance I expected the first time. How does this happen? When I went back the service advisor suggested I waited too long to have my oil changed - I should get it at 5000 miles. The oil change notification had not tripped at 8500 miles (all freeway miles).

I being a mechanical person too, do my own changes and always have. I will continue to do so until I physically cannot. I just don't trust others to do it right the first time.
