Hi there,
I wanted to get some opinons on the break in period and methods for a 2008
Altima 2.5. In the past, I have always kept it under 100m/hr for the first
1500km and tried to vary the speed so that the rings don't wear unevenly. I
don't want to mess up the compression nor the drivability so I wanted to
hear from those folks with experience.
Thoughts??
Thanks,
Andrew.

Not to be too obnoxious, but have you considered looking at the break in
directions in the owners manual? There probably isn't a 2008 on the road
with enough usage yet to know if any particular break in technique had any
effect on the longevity of the car.
Everybody who has ever owned a new car has a opinion about how it should be
broken in and absolutely no idea if they would have been better or worse off
if they had done something else. Best to stick with the manufacturer's
recommendations.

Your fellow highway travelers must hate you for crawling along at under
100 meters per hour (>300 feet per hour), or do you just drive on the
shoulder?. :-)
Old engines were manufacturer with oversized bearings and rings, which
required a break-in period before the items resized and refitted
themselves. New engines are manufactured with precise measurements, so
no break-in period is necessary.

keep believing that Will.
I'll follow break in methods as per manufacturer specifications

Impotantly- dont let it labour or run at very light load and constant speed
for say the first 1500km. (if auto then less of a problem)
Make sure you do exercise it though- keep under 4000rpm for the first 500km,
but dont be afraid to use full throttle (once fully warm- this is important
to properly bed the rings against the bores) and then progressively increase
the rev limit til you reach 1000km. There after drive how you like.
I would be using acouple of dabs of full throttle immediately you drive from
the dealer (once properly warm)
I see ALOT of glazed bores from not a firm enough initial break-in-
especially with todays diesels- and really bad oil consumption as a result.
