Changed the oil and filter in the XTerra today. Out with MaxLife Blend 5w30 and in went RGT 5w30. The hydraulic lash adjusters (lifters) seem a little more "vocal" than with Maxlife. Oh well. Running it 5k anyway, plus it was FAR. Just have two rounds of RGT to use then on to nearly 9 gallons of Mobil Super HM 5w-30 for about $3 per jug. This truck is in the clearance oil for a while.
