IMHO, Ford (like every other oem mfg in the world) is in financial trouble.....I won't go into detail but I just gave a presentation on this (industry specific) to Rotary International...Ö. Ford like the others, will look for ANY reason to void a potential warranty paid repair.....and the dealers and techs (though online training programs) are being reminded of their responsibilities..... as such, use MC oil & filters, etc. exclusively through your warranty duration.
Now, imho, MC oil and filters are really a very high quality product (which if you go to other mfgs for the same type you will pay a lot more $).
I am also not a fan of "extended oil change duration" and IMHO the oil life monitor is only a "idiot type" gauge...meaning it is the ecm software that based upon your driving style & operating conditions assesses the need for oil change frequency based upon a "value system" created by the engineers and oil companies. I'm not saying they are wrong, but.... no ,matter what study/analysis has been done in the past 30 years, there is one thing that is consistent...Ö.. 1) oil additives begin breaking down at about 1,500 miles (not that the oil is "bad" at this point, but degradation is starting) and 2) OEM oil filters at around 15-20 microns, no automotive oil filter can filter at greater than 10 microns, anything more than that, oil flow issignificantly reduced and the engine is starved. 3) Oil filter
bypass valves typically begin allowing unfiltered oil to pass at about 90 days and 4), Oil analysis (labs), unless they are a "Certified/Licensed laboratory" (which most all of the more popular referenced "labs' are not), I would consider the results as an "indicator" as compared to a real, scientific based analysis. So, in addition to oem oil change frequency, I would definitely change the filter every 90 days (regardless) and if I'm running consistently in heavy traffic type conditions (like downtown LA) then I would change oil & filter every 3500 miles...Ö.running the freeways...easy cruising....change the oil every 4500-5000 miles max.
The hydraulic timing chain tensioners are the ones IMHO that 1st suffer as a result of extended oil change duration as their oil feed oils are very tiny...and carbon related particulates are going the block those very easily...Ö and that is an expensive bill even if you do it yourself.
but perhaps this video gives a much better overview...Ö
