    I for one admire his perseverance. Many a night a lie in bed looking at the ceiling thinking to myself "thank heavens guys like Randy M are out there to repeatedly warn me about my car..."

    I don't disagree with your statements, but I will also say that I just can't figure out why Ford makes changes in some things and not others. For example, they changed the oil filter design mid-year in MY17, but I don't think there were nearly as many engines with oil filter problems as there were with oil consumption problems. And if there were, why didn't Ford recall earlier 2017s and all 2016s and 15s to retrofit the new oil filter design? They did this for the oil cooler lines, and I only heard of one instance of those actually having an issue.

    Another known failing is the non-billet oil pump gear. Since Ford doesn't release the actual cause of engine failures on those replaced under warranty, we can only speculate as to how many have actually failed due to a broken OPG, however a cursory search through these forums reveals several instances in which the OPG failure was obvious even before Ford agreed to replace the engine. Why hasn't Ford issued a recall for this issue?

    My point is that there just doesn't seem to be a rhyme or reason why Ford makes some changes, issues some recalls, and totally ignores others. And in the absence of Ford issuing not so much as a TSB on how to *resolve* an oil consumption issue rather than just stating that it's "normal" for these engines, we're all left to try to address it ourselves. I go back to what's always worked for me, and that's a tried-and-true engine break-in procedure.

    It is difficult to get a good read on what is really going on with oil consumption with this group. I don’t think the process of break in has much to do with the more serious consumption problems we read about. This engine is unique to most engines that it incorporates the oil spray system under the pistons. This system will help reduce piston temperatures and expansion along with exposing more oil to migrate past the piston. I truly feel this may be a major contributor. As for break in, I picked up my 2016 car in the first week of January in the cold Midwest and started to drive it daily. In the cold weather I could not get on it hard early on due to loss of traction on the cold pavement so I had to drive pretty moderately. I did take it very easy for the first 500 miles and kept in under 5,000 RPM most of the time. I am by no means a conservative driver, I love to rev this car to the limit when possible. Now with over 23,000 miles on my car, my last oil check had the level at the bottom hole on the dipstick after driving 5,000 miles since I last changed the oil. Probably 50% of my driving is highway miles in between occasional autocross and track days, and my GT350 consumes very little oil. I consider myself one of the lucky owners.

    This is kinda like - "Anyone wear protection and still get an STD?". Well, yes - but no one is giving the real details ;)

    I forgot he existed until you posted that. He's still at it, eh? I think I called it when I labelled him "very bitter". Just wow.

    Yeap. Guessing this may have been some of the reasons behind diff pistons and rings on the 18 YM’s.

    If you're staying up thinking about it, well perhaps it is an issue?

    I also don't think that break in will cause major oil consumption issues. Especially the issues that only turn up after many thousands of miles. Those are definitely caused by something else. Something that either wore out or broke but only after thousands of miles.

    I do think that gentle break in could be the difference between zero oil consumption and 1/2 to 1 quart consumption per oil change, though.

    This is what I am struggling with. Just zero communication from Ford. do I purchase a 2019 hoping it has "something" improved on the engine? All the talk of the 2019's having improved rings, gt500 block, etc... is just speculation. The only thing that seems strange is that the 2019's were not released/available last year when the regular GT's came out...

    The late release makes sense, actually, for two reasons. First, they have MPSC2 tires which Ford won't deliver during the depth of winter because they get damaged in the cold. Second, the side-effect of the delay was to allow the Bullitt release to take place without having to compete with the GT350.
