I already posted this in another VOA of this product for comparison but wanted to leave it here as well. This is from a quart bottle purchased from Walmart to go with the 5 qt jug for my wife’s car. I’ll try to run a sample after 5k use in a TGDI.
QSFS(p.k.a., QSUD) is one of my favorite oils especially in 5W30 (and in other grades as well) and is one of my go-to oils.
Lately with SuperTech Synthetics(another go-to oil) taking a price hike, I am looking at others. I've found regular Pennzoil Full Synthetic(non PP/PUP) at reasonable prices(5qt) at W*M. However, I've just scored some Castrol Full Synthetic or $10/5qt jug.
