I doubt Ford would want to tell you that there test is less stringent than GM's DEXOS.

Back in Arizona. Finally
IIRC Motorcraft semi syn oil has been reformulated reflecting the industry suspicions that high calcium oils propagate LSPI. Checked the oil (bottle) a while back and it noted something about turbo protection and was recommended for use the Ford turbo vehicles. Next time I'm at Wally World I'll recheck that.

Yep, it is SN plus rated now.

I believe that instead of sweating manufacturers specifications, if you simply make sure you are buying SN+ oil and change it at a sane interval, you will be fine. The next owner of your vehicle will appreciate your efforts. smile

99% of all D1G2 oils will meet Ford's "B1" spec. Ford recently released the B1 spec and not every oil manufacture have updated their PDS to reflect that. Many conventionals/syn-blends meet Ford's B1...99% of D1G2 oils are all full synthetic. Your over thinking this!!!

Indeed if the OP used Supertech "conventional" and changed at 5K the engine would not suffer an oil related failure. At such a short change the only thing which matters is the API SN+ cert.

The only true debate should be "do i need full synthetic?"

For the miniscule price difference, why not?

There would have to be a benefit. In this use there is none.
