Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2020 S6.

Transmission Automatic (S8)

The 2020 Audi S6 is specified with an automatic (S8) transmission, an 8.0-quart 0W-30 engine-oil capacity, and EPA fuel-economy ratings of 18/28/22 mpg. Across the 1992–2021 S6 complaint history, the 2020 model lands near the lower end, logging only two owner complaints in the Power Train, Electrical System, and Engine areas plus six recalls.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

In the federal record, the 2020 Audi S6 logged 2 complaints, 6 recalls, 0 investigations and 1,020 TSBs. Compared with the preceding 2018 model year (4 complaints, 1 recall) and the following 2021 model year (0 complaints, 10 recalls), 2020 shows a complaint count lower than 2018 but higher than 2021, while its recall count sits between those of 2018 and 2021. Across the generation, complaint numbers peaked in 2013‑2014 (42 and 20) and have since declined to low single‑digit levels in 2020‑2021, whereas recall counts have shown a general upward trend from early years to 6 in 2020 and 10 in 2021. The 2020 year therefore falls after the high‑complaint period and reflects the rising recall activity seen in later models, with no reported crash or fire complaints. Assuming all recalls have been performed, the low complaint volume and absence of safety‑related crash/fire issues make the 2020 Audi S6 a reasonable used‑car choice, pending verification of recall completion.
