so I have noticed that Mobil has now expanded their non-Mobil 1 offerings with this '5000/7500' monikers to distinguish between traditional motor oil and their 'new' semi-syn oil. I was wondering if anyone has any technical details regarding this new formulation for the semi-syn...

please post what you know about this oil! now that motorcraft 5w-20 is becoming harder to find, i may have to jump to use this instead.

 

I don't know about anyone else, but I have been trying to get some but none of the typical places have the 5W20 available? Do I just have to wait?

Any concerns about using a synethic blend? As a substitute, I have been using the Castrol Syntheic Blend 5W-20.

 

For what it's worth I changed my oil for first time since I bought the car and used this Mobil synthetic blend. Got it at Walmart. Figure it will work just fine but I am no expert on this subject.
