2018 Audi A7

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2018 A7.

Body PASSENGER CARTransmission Automatic (S8)

The 2018 Audi A7 is a luxury performance passenger car equipped with a gas engine requiring 5W-40 oil and paired with an S8 automatic transmission, delivering EPA-estimated fuel economy of 20/29/23 mpg across city, highway, and combined driving cycles; this generation sits near the middle of a complaint history spanning 2007-2025, with the model having experienced its lowest complaint count in 2009 and its highest in 2019, placing the 2018 model year one year before that peak and suggesting a vehicle whose reliability trajectory was trending upward through the early years of this generation before encountering challenges that would peak the following model year.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 10,000 mi; spark plugs every 40,000 mi; coolant every 20,000 mi. The big-interval services (every 20,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.
