Recommended break-in 5.4 Triton V8
[updated:LAST EDITED ON 15-Dec-02 AT 10:25 AM (EST)]Thinking about getting an Expy 03 with the 5.4 this week - been researching with dealers for a few weeks.
Wife wants to get it and drive it to FLA with the kids to see her family for the holidays.
I told her not a good idea to get a new vehicle and go out and put 2000 road miles on it cruising at 70-75 - maybe i'm old school on motor break in but its what i was taught - give a new motor lots of speed range, variation, start, stop, varying temps to let the rings seat properly etc.
Now some stealers of course say "oh with todays cars you don't have to do that" -- i still say "bull - good mechanical sense says you need to do it the way i've always heard".
I have never tempted fate and not done what i was taught - my 2 SHOs were given a nice mix of driving conditions first 3K miles and run great at 100K and 76K miles. Ditto with the 89 Probe i ran 130K miles on before trading it.
Input anyone - am I crazy - do i need to change how I think about the break in period ?

I agree with you on the need to be careful during the breakin period. But you should be able to do that on this trip, just provide the variety especially in engine speed and you should be ok. In other words, don't just hit cruise and drive at the same speed to 30 hours! 
Drive at 65 for half an hour, then 70 for a while. Take a couple of extra stops for a coffee and give a quick check on the oil, etc.

I asked the dealer the same thing when I picked up my 03 Expy. He pointed me to the Owners Manual for the truck which states for the first 1000 miles to run the car at different engine speeds. The manual also states NOT to use the cruise control until after the breakin period. Hope this helps.
