More important than brand is right amount of zddp and change interval. Dirty oil is far more detrimental to engine life than the 1200 ppm vs 1300 ppm of two similar oils. Often we read the gurus claim oil as gospel but we don't know other factors such as change interval, etc. these discussions just are not really based in fact.. I use most vr1 because its away to get but have also used gt1 and bp. They all performed similar for me.
