There are two main battles about break-in.
First, is the easy break in. Personally, I don't buy this anymore. But, for the record- here it is anyway.
Let the engine idle for 10 min then idle at 2000 rpm for 10 min. turn car off and let it settle for about 5-10 min.
0-200 miles.
Try to keep the highest rpm under 3000 rpm. Every 15-20 miles, spin the engine to 4500 rpm in first and sometimes in second gear.
200-400 miles.
Try to keep the revs limited to 3500 rpm. Raise the revs rpm to 5500 with the same frequency as above.
400-600 miles.
Go to 4000 rpm for driving limit. Raise the revs to 6000 - 6500 rpm and include 3rd gear pulls, same frequency as above.
600-800 miles.
4500 rpm driving limit. rev it to 7000 rpm and include partial 4th gear pulls.
800-1K miles.
5000 rpm limit with revs to 7500 with some pulls all the way through 4th and partial fifth gear pulls.
Use non synthetic oil for the first 500 miles, change oil with non synthetic,(it is not necessary to change the filter) then once you meet the 1000 mile mark go ahead and change it with a full synthetic and a new oil filter.
Using regular - non-synthetic - is also at your option, but pick one or the other to use from this point forward. Changing back and forth is NOT a good idea.
I personally find synthetic too weak for my motor. It doesn't have enough umph and VTEC engagement doesn't happen because of the oil pressure factor not being there. This will depend greatly on the motor and what you have done to it, however.
The other option- Break it in on the dyno. WITH a wideband and a good tune- not a basemap.
