I know I certainly haven't. haha. Just been driving how I want (through 700 miles) and not worrying about it a ton.
Literally the exact opposite of everything ive ever read about an engine break it. It really does not make sense that it would take 400 miles for the rings to begin seating. I mean really, why would the rings "refuse" to seat during the first 400 miles? Are they made some super exotic metal that somehow knows when it should start to wear in? Rings start seating from the moment you turn the engine on, the moment they being to grind against the cylinder wall, the moment the are exposed to the heat and pressure of the engine.My friend is an automotive engineer and SAE member. He says to take it easy during the first 1,000 miles. After 400 miles, the piston ring seating begins. Accelerate from 2,000 to 4,000 rpm in 3rd or fourth gear. Do not allow it to downshift, so initially you need to use less than full power, the go to full power. Note that this is a rolling start. Do this 6 times. Then wait another 75 to 100 miles before repeating the process. At 1,000 miles, the rings should be seated. The result of this break-in method is more power and longer engine life.
I don't know that proves much, since i certainly didn't baby mine, but i do agree with you that this 400 miles to start break-in is crazy talk. Id say it would be a good idea to avoid towing and any hard runs more than a few seconds, but to baby it for 400 miles? If they aren't glazed by then, they are at least 400 miles behind in the break-in process.Literally the exact opposite of everything ive ever read about an engine break it.

I did a hard break on my motor and as of right now based on the limited number of drag strip reports, I think I have the fastest stock ford fusion on these forums. BOT_Rocket ran the 1/8th and trapped 77MP, OXI also ran the 1/8th and trapped 77MPH, I was trapping 79MPH in the 1/8th.
Sure its not fact, but when you say you didnt baby yours, I drove mine hard. I really pushed the motor for the first 200 miles. They day i bought it, I probably went WOT 100 times.I don't know that proves much, since i certainly didn't baby mine, but i do agree with you that this 400 miles to start break-in is crazy talk.

When I say, "I didn't baby it," its like saying, "I wasn't very nice to him," after I beat a man into a coma.Sure its not fact, but when you say you didnt baby yours, I drove mine hard. I really pushed the motor for the first 200 miles. They day i bought it, I probably went WOT 100 times.
Agreed, altitude, temp all play into it. At the same time I think if nothing else, its good evidence to support that a strong break in does not damage or diminish the power of the engine.When I say, "I didn't baby it," its like saying, "I wasn't very nice to him," after I beat a man into a coma.
I got my first speeding ticket in many years before my paperwork was even finalized. I put 200 miles on it that first night, much of which was spent at WOT.
All I'm saying is that there is probably some other variable than break-in that explains the different trap speeds.
exactly. I am curious to know if anybody actually has the self control to follow the "baby it" break-in so we can see if the EB actually cares how you treat it.Agreed, altitude, temp all play into it.
