Motorcraft synthetic blend vs full synthetic

[Rinspeed]

At the end of the day, the Motorcraft spec just isn't that tough.

On the other hand, all oil is pretty **** good nowadays, spec or no spec. Especially if you're changing it at 5 or 6K.

Yep, and the MC spec is plastered over just about every oil I've bothered to look at here recently, so it isn't hard to find if you're a stickler for it to stay 'in warranty'

I'm looking for information on Motorcraft oils. The normal everyday Motorcraft oil used by dealerships is a synthetic blend. Ford and Motorcraft sell full synthetic versions of the oil.
Is there any real testing data with results of the comparisons of the synthetic blend vs the full synthetic counterpart?

I just recently purchased a new Lincoln Corsair with the 2 l EcoBoost. For the first 4 years or 50,000 miles of ownership I get complimentary concierge service from Lincoln. I prefer to do my own oil changes but given the service and warranty maybe I will let them do it.
If it's a synthetic plant I think I'm going with no more than a 5,000 mile change interval. Considering paying extra for full synthetic oil version.
Oil spec is 5w30 or alternative OW-30. OW-30 recommended in extreme cold. I can't even see where Motorcraft even offers a 0w30 oil.

Personally if doing it myself I will use Castrol Edge or Mobil 1 variety.

Is this your Corsair ?

used oil analysis here indicate the blend doesn’t hold viscosity well in the EcoBoosts.

What oils other than maybe top of the top tier boutique oils hold up in the eco boosts?

True but synthetic blends are mostly conventional oil. For an ECO Boost I'd use synthetic, and its usually not much more expensive,.

Just looked at the new specs (released this year) of Motorcraft 5w30 syn blend and full syn GF7A oils and strangely enough it shows a higher flash point on the semi syn vs the full syn. The full syn only shows a large difference in pour point at -30 over the semi syn.
I know these specs are minimal but I do believe the semi syn changed at 3-5 miles is a very capable oil with the newest GF7A specs
I have no oil analysis reports on my new ford as of yet…
Will updated here when I decided to do a sample.

Ford has not specified synthetic blend in their truck engines in over ten years AFAIK. They spec full synthetic.

I'll edit this. Since at least 2020 Ford Canada specs WSS M2C946BI Super Premium which is a full synthetic. The Americanos get to use semi synthetic.

2024 F150 with a 3.5 yeah the oil in the manual specifies synthetic blend to 5W30
