[QUOTE="MustangGT350FAN, post: 16143175, member: 191463"] Lets say the rate is 4% thats 1:in 25 thats 760. thats with the 2015-2018 production numbers of 18,000 total keep in mind that Romeo plant builds about 27 engines per day with 250 work days in a year, thats 6750 engines per year. for production, not replacement. as previously stated they stopped production for 2 months, was this to let the Romeo plant catch up? thats about 35 working days minus the holidays (Dec-Jan) thats about 900 extra engines, so conceivable that 4% could be a good number. here is a list of some engine failure stats keep in mind these are full production cars [font=Courier New][b]Manufacturer Engine Failure rate (%)[/b] [b]Failure rate (1 in x)[/b] MG Rover 7.88% 1 in 13 Renault 3.99% 1 in 25 Audi 3.71% 1 in 27 BMW 3.55% 1 in 30 MINI 2.51% 1 in 40 Saab 2.49% 1 in 40 Vauxhall 2.46% 1 in 41 Peugeot 2.34% 1 in 44 Volkswagen 2.31% 1 in 45[/font] The list for limited production hand built engines like lamborghini and Ferrari are 1 in 20 I am not in denial, I believe the oil consumption issues are in large due to poor break in process. Remeber, these engines are not broken in at the factory like most production engines are, it's up to the owner to break them in properly, I am one who did not follow the process, the dealer never mentioned one, and really who ever reads the manual. I did everything wrong during the brake in period, I let the car idle till it warmed up to operating temps, I used cruise control on a 600 mile trip, I babied the car the first 1000 miles. all wrong. but I was never informed of the proper way. I will bet that a majority of the high oil consumption cars were broken in the same way. It's a High Compression hand built Performance engine, with 8250 Redline, those rings need to seat properly for the engine to last. Here are some good resourses on the subject: [URL='https://www.enginelabs.com/news/dispelling-engine-break-in-myths-with-high-performance-academy/']Dispelling Engine Break-In Myths With High Performance Academy[/URL] [URL='https://dsportmag.com/the-tech/education/quick-tech-performance-engine-break-in-the-right-way/']Quick Tech: Performance Engine Break-In the Right Way - DSPORT Magazine[/URL] [URL='http://www.badasscars.com/index.cfm/page/ptype=product/product_id=82/category_id=13/mode=prod/prd82.htm']What's the right way to break-in an engine?[/URL] And they all say, if the rings do not seat you will have High oil consumption and ring failure.
