engine break-in contradiction

Armonster · 06-08-2011, 09:18 AM

Based on the opinions I have seen across different forums for different cars and motorcycles, the more knowledgeable people seem to say this: break it in easy for longevity, break it in hard for power. I went with with a little of both. I avoided WOT and 6500+ rpms for the first 1000 miles or so, but still drove in a "spirited" manner around town.

Nissan obviously recommends a break-in procedure for a reason, but doesn't tell us the reason. The question is whether that unidentified reason - which, from a practical standpoint, is most likely for longevity purposes - aligns with your own goals. Sometimes it does, sometimes it doesn't. But arguing that the manufacturer's recommendation is the only correct/safe/best way to do something, simply because it's in the manual (and without knowing why it's in the manual), is a bit short sighted in my opinion.
