This reads like your annual blood test. If you read the column for "Values should be" much like your cholesterol in that blood test, then it will make sense. Also compare the Average's to the actual results. If its higher than the average, then it may need looked at. Just like cholesterol .

I am still undecided between 4 and 6 Cylinder. My current order has the 4 Cylinder because most of the reported issues I have seen or with the 6 Cylinder. After all the experience and discussions of the last few weeks, any recommendation which one is more durable?

To be honest, neither engine is a loser in this regard, however, from an engineering perspective... all other things being equal, simpler is always more reliable, and thus I would expect the 4 cylinder to be the more reliable engine. The real question is: is it a meaningful difference? I don't think that it is unless we start seeing data that suggests otherwise.

Thanks, I think the same way. As already mentioned, most of the reports I have seen with Bronco engines going bad, were with the 6 Cylinder. I have actually not seen any reported issues with the 4 Cylinder. Also the 4 Cylinder engine has been around much longer and has a great track record.

Generally I would have loved to go with the 6 cylinder. The bigger the better and there is not much difference in MPG. I also don't care about the price difference from 4-6 cylinder. I am still on the fence, but for now I will stay with the 4 cylinder unless I see real good reason that the 6 cylinder is more reliable.

Both the 2.3 and 2.7 were introduced for the 2015 model year. Ford claims the 2015 2.0/2.3 were a "clean sheet" block design, though technically you can still trace its roots back to the Mazda engine.

This is what happens when you just beat an ecoboost engine.
Do you expect to get worthwhile data from marketing material?

I am sure that they probably had a 20 min to 1 hour breakin period and then let it rip.
Why are you sure of that? What relevance does this test have to long-term reliability, oil consumption, heat cycles, and age that a real-world engine will face?

Since I'm redoing my order for MY22, this too is something I'm wrestling with. When my order was a 4DR, seemed logical to go 2.7. Now thinking 2DR, do I need the 2.7.

Thing that keeps echoing in my head tho.... <story> My late ex father in law was a Ford truck guy. Dealer mechanic, retired to work at Wal-Mart but hung around the dealership selling cars and trucks to friends and family at invoice. I was looking for a Ranger (this is like, early 90's). Was waffling between the 4cyl for milage, 6 cyl for power. He advised me, the 4cyl has fewer parts, and will get better milage, but the 6cyl will not work as hard and therefore, last longer </story>

Not sure if that is 1990's thinking but, he never steered me wrong.
