Below is my first UOA on my 2017 Hyundai Sonata 2.4L GDI (non - turbo) performed by WIX - Atlanta.
I've run a DEXOS approved 5W30 all it's life (34K miles) with 4K mile OCI's using a Fram Ultra #9688 oil filter changed each time.
QSUD 5W20 was used with an OCI of 3,800 miles ; suburban driving conditions run from Oct. 2019 to end of Feb. 2020 in Georgia with average runs of 40 minutes (one way to work) .
I wanted to establish a worse case OCI with the QSUD 5W20 (I normally run a 5W30 D1 / Gen 2 rated synthetic oil for 4K miles ) .
*Your comments regarding the wear numbers , sodium , TBN , etc. ?
Wix - Atlanta Report:
Engine wear levels appear satisfactory for first sample.
Silicon level (dirt/sealant material) satisfactory.
Water content acceptable.
Viscosity within specified operating range.
Action: Resample next service interval to monitor and establish wear trend..
