I'm 4k into my 1st time using PYB (5w/30) in my DD (2010 Hyundai Tucson 2.4l DI) and now that the mornings are cooler, 1st early morning start it still seems more quiet than the PP I was using, same as Kendall and MS5K previously. Or it's because I'm almost up to 75k on the engine and that's just the way it is, or it's just me. I dunno, just seems to like PYB. So it's cheaper and since I do 5k OCIs, good enough for me. Just picked up another 5-qt jug today and it was $15.99 OTD (local BX). Was going to go the new PP? but no 5w/30 again, so PYB it is, again. Of all these years, hard to believe I'm on my 1st time use of PYB. So far so good, just saying. And just checking the oil level @4k, it's still on the full mark on the stick. I'm usually down 1/2-qt with the other oils used, so that makes me a littler more happy.
