No link- sorry... I think there were several references within threads and not necessarily it's own.
Good point. :doh:
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.
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??

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 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:
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.
