WM Online is selling all grades of Quaker State UD Synthetic for $16.61/jug as long as you purchase six jugs at a time.
Currently, I use either Mobil 1 EP, Mobil 1 or Idemitsu ZePro for my personal and friends' cars (non-customer) depending on my mood. Switching to QS would save me (or the person) 30-40%. QS is GM Dexos 1 Gen 2 approved for every grade.
All of these cars are late model Honda, Infiniti or Toyota vehicles specifying 0W-20, 5W-20 or 5W-30 and have service intervals between 5K-10K miles. Most are closer to 10K miles though.
Is there any reason why I should not make the switch?
