Castrol EDGE 5W-30 Advanced Full Synthetic vs. Quaker State 5W30 Ultimate Durability Full Synthetic

The QSUD 10W30 I got a few months ago does not have any dexos label on the front, and on the back it only says "meets or exceeds" SN+.

That’s not shocking since 10W-30 isn’t a Dexos grade.

I'm curious too, what happened with QSUD? I've got a jug of Magnatec sitting here for my next oil change. I've never tried that one before.

Personally, I like how QSUD 5W30 and 10W30 run in the Toyota/Lexus 2GR-FE and 2GR-FSE V6. Have used multiple synthetics of various grades in those engines and found the QSUD to be the quietest. Helped with a questionably maintained 2007 Camry with oil burning and VVT ticking. Reduced the consumption to less than half and valve screens are still clean 70,000km after changing. Now, that is only two variants of an engine series. Hyundai's get Mobil or Castrol. Everything else, except Euro, get Valvoline.
