Im not an expert by any means, but whats the big deal over NOACK? Unless you drive a car that runs really hot or a performance vehicle is it really that important? I would think just by looking at the stats... TEOST would be something to be more concerned over? Or even TBN? I see all this down talk of the new PUP because of the NOACK readings... but what about other aspects of the new oil? Thoughts?
