A number of members have weighed in on this in previous threads. No one has found anything that indicates there is a special factory oil fill. I inspected the original oil when I changed it, even cut open the filter, it looked/smelled/felt like just oil.Has anyone tested the factory oil before the first oil change? Has ford put something in there ???
In the absence of any answers I just dumped my 5W-20 MotorCraft Synthetic fill with Ceratec that did nothing to solve the cold knock sound. Replaced with PUP 0W-20 synthetic, no Ceratec. I didn't bother replacing the filter as I will get the regular oil change done when the Oil Life Monitor (OLM) says so. This was just an experiment and I am supposing that the approx 1/3 quart of oil and Ceratec in the filter won't make much noticeable difference in 10 quarts.I have seen lots of people try thicker oils, different brands etc., has anyone tried 0w-20? did it make any difference?
The information a corp like Ford publishes is sometimes up to interpretation, even not publishing any information is. Unless they are forced by law or to prevent litigation by not deliberately postponing and delaying information that could prevent damages, I am sure a corp will not deliberately publish any info that would hurt their reputation and business just for the sake to be transparent and honest to the public. I can relate very much to NoVaGT's point of view there. Ford eventually decide on what is 'normal' independent of 3rd party research and test results.Could be. But in that case, the theory that the noise is normal wouldn't be valid anymore.
Ford's silence can only mean two things. Either they have no idea what's causing it, or they know it's not normal and are lying to us.
I don't expect them to "publish" the information, i.e. to issue a press statement or something. But they could mention the cause, or at least hint at it, in the TSB itself. I've seen a lot of TSBs which went like "if a customer expresses concern regarding this issue, then the cause is xxxx and the resolution is yyyy". They're not opposed to giving this kind of information in a TSB. Whereas in this case the TSB sounds more like "if a customer is concerned about this issue, just tell them it's normal and send them home".The information a corp like Ford publishes is sometimes up to interpretation, even not publishing any information is. Unless they are forced by law or to prevent litigation by not deliberately postponing and delaying information that could prevent damages, I am sure a corp will not deliberately publish any info that would hurt their reputation and business just for the sake to be transparent and honest to the public.
Do you put the ceratec in with 10qts in engineI threw in a bottle of Ceretec about 400 miles ago and it immediately stopped the tick and it hasn't come back yet so far. Just before that it was happening everytime it would sit idling at operating temps.
