Been lurking here for over a decade whenever I'm seeking some perspective or education on various oil/filter topics. However, today is the day that I make an account to post this PSA.
If you're a 5w40 Quaker State Euro Full Synthetic user, take extra care to check your 5 QT jugs to make sure they're not underfilled from the manufacturer.
Out of 12x "5 QT" jugs at my local Walmart, 10x were underfilled with only ~4.2 QTs. All jugs had the factory seal in-tact, and all underfilled jugs were underfilled to the same degree.
