I want to get some feedback on Motorcraft oil. I have toyed with the idea of going from Havoline 10W-30 to Motorcraft synthetic blend 10W-30 for a few resons, but have a few questions:

The car has 150K on it. Should I just leave it well enough alone, and stick with what I have been using since I bought the car 25K miles ago? It doesn't use hardly any oil as is.

Any real world potential to increase fuel mileage and/or "protection" of internal parts?

What did the car leave the factory with? Conventional or Syn. blend?

'Preciate it guys.

just stick to regular oil. A semi-syn blend isnt going to do anything for you

if the oil you are using now is working....then why change, keep using that oil

Its a Ford, nothing special, regular 10w-30 is enough
