I know everyone is really passionate about this but how about a reasoned discussion shall we.

I noticed my 2014 Mustang (5.0 with traditional Port EFI & 8 quart sump that averaged well over 20 mpg) called for a 10,000 mi oci by the IOLM.

A 2014 F150 3.5EB (GDI, Turbos, 6 qt sump and 16 mpg) also called for 10,000 mi oci by IOLM.

A 10,000 mi analysis on MC Blend from the Mustang was difficult to tell from the virgin sample.

A 6,000 mi sample of Mobil 1 from the EB looks like it's been shredded. Low-7's cSt in viscosity, near 10% fuel contamination and 6x the iron level and half the TBN of MC Blend in the 5.0 at 10,000 mi

Given these "challanges" is the consensus still to follow the oil life monitor? I will admit a 10,000 mi OCI on Synthetic on my newer F150 18 3.5EB would make me more nervous than a 20,000 mi OCI on conventional in my 14 5.0 Mustang.

What is the consensus on modern GDI Turbo engines with moderate oil capacity, modest mpg and a fairly aggressive IOLM program?

Follow the IOLM or change earlier?

My parents had a Ford Escape with the oil life monitor, but I'm not sure it actually did any monitoring. Just reset and go off very 7500 miles. Of course they changed it before 7500 miles, my father isn't a big fan of GDI engines and longer drain intervals.

I don’t have the turbo but have DI in a 5.3L GM on 0w20. At 40% remaining ... changed my $5 filter and that makes room for a quart of HD30 ... $8 & 10 mins ...will finish the OLM

Change way earlier.

I only have an OLM on the church van. If I went by it we would change our oil about every 7 years.

All my IOLM default to 365 days if you are a low miler.
After three two-day open track events within just a few weeks my Mustang called for a 1700 mi OCI so I'm fairly certain it actually does actually do something (I had previously thought it had a 3,000 mi minimum just like the 10,000 mi maximum but apparently not).

Sounds like you have data to justify earlier change (or a reason to find better oil). So I'd definitely do that.

As to the oil life monitors, I'm pretty sure that the OEM's are putting in no small work into them. So I don't know what the problem is--seems like they ought to be good and conservative. That or maybe Ford doesn't think the wear and tear on the oil is that bad--we might think it awful, they might think, gee, it's worn out oil--what did you expect?--don't you feel good about getting all you could out of that oil?

Especially with Ford, I would never go with the OLM, if you want to keep the car past warranty.
Ford provides zero goodwill past warranty and even in warranty their warranty coverage can be difficult to get.
Ford's goal is to minimize perceived maintenance costs to potential onwers with the 10,000 mile OCI and to get cars past warranty.
1st hand experience in buying and maintaining 1,000s of Fords for a large private fleet.

If they were my cars, no more than 5,000 mile (or less if OLM calls for it) OCI with SN+, SG, D1G2 oil with appropriate Ford rating on the bottle.

I know the Ford 2015+ OLMs will count down ~2% per week even if the vehicle isn't driven. If the vehicle sat for a year without ever being started, the OLM would go from 100% to 0%.

My thought on OLM's is, they are just a hours in use timer. It doesn't know, or care what type of oil your using. I can reset the olm on my wife's Equinox, any time I want and it will rest the timer. When it goes another 5k mile's, it will tell you to change the oil again. I feel it's just a reminder for people that never give changing their oil a thought. If it actually could tell if you need to change it, you shouldn't be able to reset it unless you changed the oil.,,,

That's not really an OLM then, that sounds more like a maintenance light instead. Two of my cars have the same light, and I'm supposed to change the oil every other time (5k rotations, 10k OCI's). I'm actually ok with that. But from what I've read here, other makes do have OLM's that take into account idle time and gas through the motor (heavy operation burns more gas and shortens OCI).

What you've noticed about EB engines is spot on. I've been saying this for years on BITOG. I have a first gen EB and noticed these things back in 2011. Every so often I post about it. So it came as no surprise when "mistreated" EB engines started showing up for timing chain replacements. Not to mention the near constant troubles with cam phasers.

An honest assessment of what is going on in modern engines really does point to the need to manage oil and viscosity better than simply going with the OLM and viscosity requirement. Those who make the statement that the "manufacturer knows best" give nothing more than "lip service" to the fact that the manufacturer is in the business of selling new vehicles, and not in the business of keeping them running beyond their "useful lives" They are also in the business of performing repairs. The fact that they last as long as they do has a lot to do with competition and EPA/environmental requirements.


People who count on their fingers should maintain a discreet silence.

I'm just mystified how I ever got over 140K miles out of my 2004 Corolla S without one.
