Castrol Edge EP 5w30 2016 Ford F-150 3.5 EcoBoost
First UOA on my F-150 and I’m pleased with the results. About 80/20 city/highway. I work 4 miles from home. Mostly short trips, some off roading, and a little bit of towing about 6.5k lbs. I didn’t expect wear numbers this low, even for the short-ish 5k run. The additives referenced was Chevron...

OEM recommended is the Motorcraft Semi-Syn 5W-30. Because my dealer does mine, that is what I have used in my Current Fords, and previous since 2016. No issues. I drive them hard.
If I was doing my own, I would be using Driven DT40 or Valvoline's Full Synthetic 5W-40 for any 3.5EB equipped Ford. Personal preference more than anything.

Motorcraft Synthetic Blend 5W30 is NOT the OEM recommendation for the gen4 Expedition, 2018-24.
Your dealer is screwing you over if you are getting a gen4 Expedition serviced.
Motorcraft 5W30 Synth Blend web page - Motorcraft web page for 5W30 Synth Blend - shows a “Fits These Vehicles” list and 2018-2024 Expedition is NOT on it.
Ford specifies WSS-M2C961-A1 oil spec for the Gen4 Expedition. Motorcraft Full Synthetic 5W30 meets that spec. Full Synth 5W30
Motorcraft 5W30 Synthetic Blend does not.
Nope, 100% incorrect. You will find 2 images. One is the 2020 Spec directly from the current revision of the manual, and the 2nd is the 2025 again directly from the current revision of the manual.
2020
2025
SP at the end of the part number is the blend, FS is the Full Synthetic. While the 25 spec lists both, the 2020 lists just the Blend. You will also notice the different spec on the 2020.
Manual is the source of truth and what matches FDRS. I can pull that up later when I get home, if you want to see proof there too. That is what the dealer goes by. The ford full synthetic, while slightly better. In independent tests the Blend does absolutely GREAT even under the recommended ~10K change recommendation.
Even the F150 PowerBoost(Hybrid) standard is the same as the 2025 Expedition, and comes factory filled with the Blend. Again, MANY PowerBoost owners have done oil analysis and it has come back that they could go longer.

I was concerned about this on my last oil change. Ran from January to August. Tons of short tripping all winter long running kids to/from school 5x a week driving a 1/3 mile round trip. 60+ idle hours, with OLM reading 24% at 4200 miles. So I changed it and sent a sample in.
Pennzoil Ultra Platinum 5w-30 still well within 30w viscosity, and fuel dilution was doing just fine.
Love the data! So basically the worst conditions...other than towing. You could have easily gone MUCH longer!

The only towing was very light. Under 2K lbs for ~300 miles combined which I would equate to no towing. Otherwise, I was genuinely concerned that the sample would indicate fuel dilution and or low viscosity.
Yes, I could have gone longer, but it was just convenient to change on that day. My little guys love to work on stuff. So on that nice August afternoon, we all slid under the truck together to make a 30 minute task take over an hour. Loved every minute.
Guess who makes Motorcraft oil? ConocoPhillips. Guess what other brand ConocoPhillips makes? Kendall Oil.
Kendall oil has a better additive package than MC for less cost.
I use Kendall GT 1 full synthetic 5W 30 in my 2000 Expy and I have over 250,*** miles.
Great info! Thanks for the tip. Have free oil changes at the dealer for life...so doesn't help me much. I am sure it will help others.
LOVE IT! Keep teaching them right!

If you drive newer engines hard, 0w40 or 5w40 it is. Heck my GT500 calls for 5w50!

I use mostly Mobil 1 5w-30 full synthetic and filter. But I'll use other brands if they are on sale.
5w-40 sounds good for my climate, especially in summer. I may try it.

sorry I'm late to this party.
I suggest saving a copy of the PDF in case Ford decides to redo their webpile and loses these.
