There is nothing ironic in my statement. I base my conclusion on facts. I do assume people do not Photoshop their used oil analysis reports. I think a reasonable assumption. I've only seen one report that looks a bit suspicious.


To get the viscosities people are getting in UOA's there has to be 10+% gasoline in the oil. That is the math.


How many engines have reached 150K miles?


This stuff does not keep me up at night. I don't own a EcoBoost engine. I am just looking at them. Most of the fun in making a new purchase occurs before the final sale. After that if you have made good decisions, things get pretty boring.

Or so you think. One never knows about anything on the Internet.

What math? Numerous ways to get viscosity sheared down. You're just focusing on dilution.



There are a few High Mileage Ecoboost threads here. Hit up the search.

200,000 miles are about 6500/7000 engine running hours. With luck a gasoline powered motor is good for 8500 + running hours before major internal repairs other than valves/head gaskets. Overheating usually gets those first. Usually high mileage usage taper down rapidly as vehicle rusts out and it finds its end at near 300,000 if not wrecked/totaled.

OK. I found this thread. Does it explain how reliable the EcoBoost has been? Perhaps fuel diluted oil is the common factors in these failures?

You obviously didn't look hard....

Yes, there are some with timing chain issues. There were timing chain issues in the Modular V8's too. 4.6/5.4 had them as well.

Me thinks maybe there is a hint of troll in you....

The intelligent oil life monitor is based on an algorithm that Ford uses. Its described on their web site somewhere. They have an arbitrary cut off of 10,000 miles or one year maximum, so they give their formula a big margin or error. Its based on mileage, rpm, operating temperature, and time between use and probably three or four other factors.

I was curious so I UOAd my 3.7L at 5K miles and when it finally went off at 8K miles. The oil had plenty of life left in it even at 8K miles, and I would say my driving habits were harder than most; A short commute without a lot of time to heat the oil and very little highway use.

The monitor doesn't like short trips at less than full operating temperature and it especially doesn't like the car to be parked for days at a time.

I decided to quit obsessing about oil changes and worry about the other stuff that I usually neglect. So I had the kid change the diff oil at my last change. Hey, I'm only 130,000 miles early!

It's true that the Ecoboost had fuel dilution, but that doesn't seem to have hurt anything, and it seems to have gone away with the newer engines anyway.

Think OEM changed the HPFP numbers.

I'm having trouble finding used oil analysis reports that indicate the problem has been reduced. First I have not be able to find any reports on 2014 Ecoboost models, so they may be better, but have not seen any reports to verify it. The latest ones are 2013 models and they are not good at all. I think the jury is still out on whether or not any improvements have been made. I suspect Ford has to improve the PVC system to make a significant change.

I haven't had any fuel issues (knocks on wood) and the only time the oil "thinned out" was when i went nearly 11K between changes.

Mine counts to 16000 kms, winter, summer, WOT, cruising, towing, desert, blizzard etc. Not sure how intelligent it really is, but I toss in synthetic and don't worry about it.
