I'm with ya on that! We've talked about this in the past and I agree, it made the engine surprisingly quiet/smooth and I couldn't believe that I got 30 qts/6 filter from PB's FAR.
Right now, I am on a Quaker State Conventional kick and it seems to be similar to the PEAK in terms of it's quiet/smooth operation at an even better price than the PEAK
Both are very high in boron. I am convinced oils high in boron will cause many engines to run very, very quietly.
According to the PQIA testing, the PEAK and Quaker State Conventional both have 222 ppm & 224 ppm of Boron respectivly so, it seems about right.
