2021 Audi SQ5 Sportback, 3.0 TFSI, Ravenol 0W20 (VW508) w/OEM Oil Filter, 4,844 OCI, and 17,849 total miles. Really curious where the Moly came from, given I ran the same oil & grade in the last OCI. Happy to finally see a downward trend in Fe.
Replaced with Ravenol 0W30 (VW504/507) and OEM Oil Filter. Initial observations is engine is much quieter - same oil I use in the '23 RS5 Coupe w/2.9L V6 TT.
Will continue to maintain 5k mile OCIs.
Blackstone Comments: Wear is either lower or stable relative to the previous samples from this Audi 3.0L, leaving us with no concerns about the health of the engine or how it is wearing. The low flashpoint of 370ºF shows fueldilution at 0.8% of the sample volume. However, with wear metals looking good and no effect on viscosity, it's not a concern. No signs of substantial contamination from coolant or dirt made an appearance. Potassium and sodium, which indicate coolant, are low. 7 ppm of silicon rules out dirt from unfiltered air. Solid results at 17,849 miles on the odometer.
Note: Missing UOA at 8,459 miles is due to dealer performing 10k check and not capturing an oil sample.
