Okay, here's the update, for what it's worth.
As you will recall, when they put in the additive, they told me that I could still change my oil in about 1800 miles, which was my normal interval (5000 miles). They said the additive caused the parts to properly seat and the solution would be permanent. However, the "ignitor" tick came back as bad or worse than before after I changed the oil.
Now, they are saying that my dealer must have misunderstood them. Instead, the additive must remain for 5000 miles. Personally, I think this is crap, as the dealer representative has proven to be very good with details -- I think Ford is just buying time. The first time the additive was put in, the dealer had even asked whether the oil had to be changed before putting in the additive, to which they said 'no.'
Now, they want the oil new (within the past 500 miles), and they want the additive in for 5000 miles. So, they sent a new bottle over today, and it again stopped the "ignitor" tick almost instantly. Of course, I have my doubts over whether it will be a permanent fix.
Several folks have mentioned they didn't get the "ignitor" tick until after they changed the oil the first time. Since I have been told that Ford is dumping in this additive at the factory, I wonder if it is only hiding the problem temporarily. The million dollar question is whether those with ticking after oil change got it because they change the oil after less than 5000 miles. I doubt it matters, but the question has to be asked.
Note, they are now saying the 75w-140 gear lube solution was for a different tick, not the one I have. I don't have anything more on that.
As for the "lifter" sounding tick I now have at idle, they are still trying to figure that one out. I'll post more on it after I have all the details.
