I would agree with your assessment, but I doubt everyone else will. Some will break it in hard, some will apply load cautiously, and some will baby it. The latter group seem to have the most problems. Other manufacturers are often more specific about their "babying" instructions and I've found that many people err on the side of caution and (IMHO) don't do themselves or their engine any favors.Ford's break-in recommendations are not very specific regarding engine load. They only state to avoid "extended" periods of WOT. The phrasing of the question assumes that the recommendation is to go easy on the engine, but that isn't really clear in the instructions. FWIW, I assumed that specifying "extended" periods implied that brief periods of WOT were acceptable, and drove accordingly (once the oil was warm). I strongly believe that I did follow the break-in instructions.

I think you answered my question without being specific. :cheers:In this case I read the manual and followed it.There are varying opinions on how to break in an engine.I have always done a hard break in on previous engines and never had an oil burner.For the first hundred miles the manual recommended varying rpms which is what i would expect and no "extended" WOT use.They did not say to keep it under a certain rpm as some manuals tend to do. I have the feeling these engines have probably been spun and tested and properly seated right out of the factory. If this wasnt the case then the three or four people who handle your car in transport could be determining how well your initial break in goes. My car had ten miles on it new so who knows??
I would tend to agree, but the discussion (again, IMHO) usually revolves around people following "break in instructions" that don't apply enough stress to the engine and (can) lead to issues down the road. Again, anecdotal, but I have seen enough to be a believer.Engine break in is highly overrated and over-discussed. The only thing that really matters is that the engine oil be at normal operating temp before running it hard. Ford seems to consider this to be 170 degrees or greater. The OP's car has a warranty issue.
Is that not crazy?What he said - my never tracked 911 can go through a quart of oil in 1,000 miles. If I do a 3-5 hour roadtrip with speeds in excess of 110mph it will burn even more oil. I've put over 84,000 miles on the car - runs like a champ still but high performance cars can eat oil. Porsche NA put a bulletin out that losing up to 1quart of oil per 600 miles is acceptable for the 997.
I need more miles on the GT350 before I make an assessment.
I remember that bulletin and if my car burned that much oil, the dealer and I would be having a long chat regardless of anything from PCNA. That said, before they moved down to the old Ford factory they (PCNA) were right around the corner from my office and the local dealers get (IMHO) some special treatment for them and their clients. I like your style. I'm getting my car this weekend and I'm going to break it in by driving to work and run errands for a week and autocrossing it for two days straight the next weekend. :cheers:
Agree. I'm sure the folks in my surrounding area wonder what the hell I'm doing when I do this, and I'm sure the GT350 will make even more of a racket. My kids enjoy it, however, and my daughter's favorite phrase is always "Go faster, daddy!".Absolutely agree with you gravedgr. Op temps in normal range and then high loads (outside of anything close to lugging) and various rpms. Decels are VERY important as well - normally you might be inclined to go clutch-in but during break-in, decel's are very important and should be done at every opportunity. Keep RPMs varied. Note that *most* break in is done within first 20 miles or so. Don't delay with whatever your break-in strategy is.
