More than 90% of driving in our 2015 Volt is in full electric mode. Have always gone by the OLM which times out after 2 years. The Volt is too low for my ramps so I have the local Chevy dealer do the oil/oil filter changes (Dexos Service) and I take care of everything else.

Have settled on PUP 5W30 for my 2015 Kia Optima EX (2.4L, non-Turbo). Thought about using Mobil 1 ESP 5W30 but the cost and possible performance hit from higher cSt kept me from doing so.

I've used PP and PUP for a number of years and, in recent batches, have found that there is less valve train clatter on a cold start with PUP. For that reason alone, I'll keep using PUP.

I have a Kia 2.4L GDI and use PUP 5W30 and OEM filter. 5W20 is allowed, but I prefer 5W30 because of fuel dilution. The engine is also quieter with the thicker oil.

My call would be a synthetic 5W30 meeting the required specs and an OEM oil filter. In the past, there have been some issues with after-market oil filters and Kia issued a TSB strongly advising the use of their filters. To avoid any possible warranty issues, I use OEM, which is a good filter.

Same experience as the OP. Amazon pics showed GF-6A/SP on back of PUP 5W30 jug, but received older GF-5/SN+ version. Date code on bottom of jug was Jan 2020. Was hoping to try the new stuff but decided it's not worth the trouble of returning it. Besides, I have a needed oil change coming up.

Amazon recently showed the Pennzoil Ultra Platinum 5W30 with the new ILSAC GF-6A and API SP rating on their website. I bought a 5-qt jug and the oil I received had the old SN+ rating with a manufacturing date code of Jan. 2020. Not totally unexpected since the new specs didn't become official...

The OLM on our 2015 Chevy Volt is based on time.. Two years is equal to 100%. The first of two free oil changes was done with only 450 miles on the ICE.

PP and PUP both have SN+ approvals but PP also has Dexos1 Gen2, which might be a better choice for TGDI applications (reduced timing chain wear, etc.).
