Here's one from my brother's '02 Altima-he ran it 11K, all through the fairly nasty winter we had here, on Valvoline Durablend 5W30. I switched him to QSUD 5W30 & a Hastings/Casite filter that I had scored from RockAuto for a decent price-but apparently my concern was unwarranted! He does do about 99% highway driving-but it did sit outside every night & while at work. End cap did pop off when I cut it open, but the leaf spring was holding it together.
