Well, assuming Ford has the IOLM algorithm right.
I just have a hard time with Ford concluding a 10k interval is right for everything from a normally-aspirated, port injected 2.5l engine to a direct-injected, turbocharged 1.6l. And, as far as I know, Ford is the only major manufacturer claiming a 10k interval is OK on a DI/turbocharged engine using a conventional oil (almost all conventionals meet Ford's spec). As others have said, this regimen will likely get throught the warranty period, but beyond that...?
Where is Ford making that claim? I've certainly never seen it in print. There's an OLM in the cars from 2011 on that can go "up to" 10K miles, which is actually less than most cars equipped w/an OLM? Prior to that, they said 7,500K miles. So, I'm not really sure I get all of the hand-wringing on this one.
They've obviously said that their filters are good for "up to 10K" as well, and based on my own experience the 820S at least can go twice that long without problems. So, 10K on a Motorcraft filter on a maintained engine doesn't seem close to the edge, at all.
My 2012 Focus manual says the IOLM will require an oil change:
"7,500-10,000 miles - normal commuting with highway driving, no or moderate load/towing, flat to moderately hilly roads, no extended idling.". In other words, pretty much how most are driven. And I bet all current Ford manuals for all engines say the same thing.
In the Ford Focus community, 10k seems a typical trigger point for IOLM followers.
My comments were not about the oil filter, which I don't doubt can handle 10k. It was about the interval generally.
Yeah, but that's not a mileage requirement (like the older Fords that just use a countdown timer), it's still an "intelligent" OLM based on operating conditions. If it's triggering for most folks at 10K, then I imagine that's because that interval is suitable for their driving conditions. And again, keep in mind that it's capped at 10K or 1 year, which (at least in terms of mileage) is a lot more conservative than most OLM's.
How many UOA's are there on this site where oil that has gone 10K isn't suitable for service? Not saying it can't or doesn't happen, just that it's pretty rare--and I haven't seen any evidence that the Ford OLM has pushed out the OCI too far.
