I also had the exact same experience with QSGB years ago in my Corsica. Exact same thing happened when I switched it out for Valvoline.
Based on those two experiences, I will never use QS oil again. Just seems like my vehicles doesn't agree with it. Guess there's a reason why it's "cheaper" than the other name brands.
C'mon...I will bet money on this, do you really think there's such a big difference between QS & PYB that shakes and rattles are the results ?
Yes, I do. I can't explain it but those are my two experiences with QSGB and I'm not happy with them. It can say whatever it wants on paper, but experience counts much more to me than what is printed on "paper," especially when I'm spending money on it. The two times I used QSGB, my vehicles ran differently and not for the better. To be honest, my Corsica from years ago ran better on SuperTech than it did on QSGB. Those were my experiences, just sayin.
