I'd like to keep the thread on track with only these three oils:
-Quaker State Conventional
-Quaker State High Mileage
-Pennzoil Yellow Bottle
Walmarts in my area seem to aggressivly discount both of the quaker state conventional and high mileage formula's. Not so much for PYB or other brands. It makes sense to buy them over the $.50 cent difference of supertech. But is there really that much difference in formulations? A long time ago I read the QS conv and PYB were nearly identical formulas minus a tiny little tweak in the additives to differentiate the product. That was back in 2010 that I read that, so times have probably changed.
