Break in new 3.5EB?

[TopherSho]

Ok ford says 'drive it but don't be an ass' .. i just dont buy it.  Merc/Audi high performance engines have break in rituals or at least rules.  Since were making more power with similar gap-tolerances it just makes sense.

Anyone have any guidences?  my initial go to is buy two crates of Royal Purple... not a break in oil,  but a oil with extra zinc/film strength.  In my head it will lengthen the break in period, but also cut down on over abrasive rings/cams/bearings on running for the first 1000 miles under light / moderate loads with no tune.

thoughts ?

I would still do a break in and maybe do some testing so you can tell us if it did anything?

Ford is correct.  Not a lot of special breakin is required, the engines come with normal oil from the factory.

You can observe the "avoid WOT for the first 1,000 miles rule", but otherwise drive normally.  Will not hurt to have RP HPS as you stated (not the SAE version).  Change oil after that 1,000 miles, then go your merry way.

ok,  thank you both!

plan will be light driving,  under 3000 rpm.. but to fluctuate the rpm slowly with RP with extra zinc/film strength,  then a full flush @400 miles and again @1000 miles.

then drive stock still but more 'normal' driving with limited WoT to 1500 miles

After 1500,  drive it normal,  @2000 miles change the oil back to normal oil, start re-tuning.

Listen to both of them. A proper break in needs to be done.

Sounds good.
