I was suggesting he was incorrect too but i didn’t want to be rude....
The Owner's Manual doesn't show any difference between summer and winter. so it's 5W-30 year round.

I understand. Back in the day sometimes you would see in areas where it got really cold where cars would run 10W-30 in the summer and 5W-30 in the winter to get the oil to flow when it was -20 outside.Should have worded it different... i meant like the winter weight vs running temp weight. 5 (Winter)-30 the W is an oil cold flow rating. He was claiming he uses 10W-30 which would mean a winter or “cold” flow weight of 10 instead of 5, which i thought was incorrect, which you verified.
This was my 1000 mile Oil Analysis:Please post your oil analysis. I intend to have this done on my 17 Expedition as well. For curiosity if nothing else. I've done it with my 2006 Honda S2000 the three years I've owned it. Oil looks good at OEM maintenance schedule or annual before winter layup which may not happen this year since I'm now in Virginia. The Honda has a Maintenance Minder and computes oil change intervals. I've been running 10W30 Royal Purple in this engine. Will see what Ford puts in the truck.
I'm a believer that full synthetics are better lubricants. My wife's Subaru 3.6R has two oil change intervals and the full synthetic is twice as long as conventional oil. There's a lot of hype in motor oil but on the grand scheme of things full synthetics are a minimal extra cost.
BTW there an aftermarket dual catch can in the S2000. No blower and minimal oil caught since installation Another curiosity item. Engine is injected at the intake port so fuel is diluting any bypassed oil vapor anyway.

It was the factory semi-synthetic oil. 5W-30Which oil? The factory Ford oil I assume? (should show in the report header which you masked off probably 'cuz your home address is there. ).
