So the maintenance garage uses El Cheapo generic bulk 10W30 in our CVP's. I was wondering if Ford Motor Co by chance has issued a TSB or similar which okays the use of 10W30 in the CVP, instead of the 5W20 semi-syn which is specified? I saw the ID label for the bulk 10W30 and it did say semi-syn, for what its worth. I can also say that on cold starts with these winter temps below 30 deg F the car cranks slow on start-up and feels sluggish for the first couple minutes of driving until the temps come up. Figure its the 10W30 in that 5W20 spec'd engine that's behind those issues. My assigned CVP is a 2006 and out of warranty, so my guess is they only put 5W20 in the cars with active warranty still in force and then pour the cheap stuff in once the warrany is done.
