I have a 2008 Altima Coupe 2.5 S. I dumped the factory fill at 4K miles and have been running 6K mile OCIs using 5W-30 Valvoline SynPower, Castrol EDGE, and Pennzoil Ultra since with DENSO filters. The QR25DE engine seems to like them all equally, at least according to my butt-dyno. I got a UOA done on the EDGE that was run between 22K and 28K miles on the odometer and it showed good wear numbers and lots of active additive left. (Click
here to see the UOA.) As a result, I will probably increase my OCI length to 7500 miles.
One thing I would recommend is using the longer filter size. Rather than a PL14612 equivalent (i.e. what some refer to as the "shorty"), use a PL14610 equivalent. The only difference is that the PL14610 is a tad longer and gives you some added filtering media. I've cut open a DENSO 150-1010 (click
here) and a PureONE PL14610 (click
here) and will continue to use them on my vehicles. I also wouldn't hesitate to use a WIX / Napa Gold, Mobil 1, K&N, or Bosch Distance. Based on what I've seen and read, I'll stay away from the Made in China OEM filters which have cardboard endcaps.
Enjoy your new Altima! I'm still loving mine after two and a half years.
