My WM always has a lot of QUSUD 5W20 and 5W30 available on the shelf ...My vehicles can use either weight , so with QSUD what specifically am I missing (additives wise ) that should sway me use to M1 or Pennzoil Synthetics (when I can find them in my weight(s) at WM) ? Applications are typical suburban commuter / grocery getter ( '10 Hyundai Elantra PFI engine , '07 Kia Sedona PFI engine)running standard OCI of 6 months / 6500 ~ 7500 miles with Wix filters . No turbo or DI engines to contend with - your thoughts ?

I'd pay more attention to how the oil makes the car feel than what additive package it has. And I'd definitely choose the 5W-30 over 5W-20.

Buy the least expensive oil that you care to use. In Georgia, any API SN 5W-20 or 5W-30 is fine...conventional, synthetic...it really doesn't matter here. Even QSUD is pretty overkill for your application. The QSUD 5W-30 has a lot of OEM certifications including those for some turbocharged engines; it's way more than enough for your use. I'd personally buy a 5-quart jug of Pennzoil or Havoline in 5W-30 and call it good.

I've been using 5W20 Shell and QS synthetic oils in my 2011 Kia 2.0L and 2.4L with no issues. I buy when on sale at Menard's and BJs Club. Usually pay $3.50/qt or less. However, always use M1 or Syntec 0W40 in my 2005 1.8T Audi because of VW 502.00 requirements.

If you compare VOAs and UOAs, you'll find that the metallic adds are very similar between any of the SOPUS syns and M1 in the same grades. As for non-metallic adds and basestock blends, who knows?

Thanks for the replies ... Interesting to note my WM has replaced a lot of synthetic 5W 20 oils (M1 , PP , etc.) with 0W 20 oils which Kia / Hyundai have not authorized , while QSUD is always available in 5W 20 .

Additive wise?basicly the less metal count the better.(usually.why you think the market created coolant without nitrate phosphate or silicate.yep wear)
