I get a good laugh when I see Motorcraft Semi Synthetic. The world has moved to full synthetic. Conventional and semi-synthetic is special order at Walmart. The shelf seems like its a full synthetic convention.
Why would Ford push this semi-synthetic?
Most full synthetics are just semi-synthetic if truth be told
So maybe its truth in labeling.
Plus "synthetic" may be good for extended drain but the more the oil is cracked and isomerised the less "clingy and cleanie" it becomes
so its not without compromise, depending on the formulation.
In the days of less stressed engines, It was a decent oil comparable to
MC5K, and QSGB. IIRC it had a lot of mystery FM and it seemed to do well with lugging and general hyper -miling.
Plus it has been Honda Motor oil for ages.
So no need to trash it.
