2008 Audi RS4

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2008 RS4.

Body PASSENGER CARTransmission Manual 6-spd

The 2008 Audi RS4 is a passenger car specified with a 10.0-quart engine-oil capacity, a 5W-30/5W-40 API viscosity requirement, and a six-speed manual transmission, carrying EPA fuel-economy ratings of 13 city/20 highway/15 combined mpg. That service profile—especially the large oil volume—anchors its mechanical identity for anyone researching this model. In reliability terms, the 2008 model year records just three owner complaints, with Engine & Engine Cooling cited as the top complaint area, alongside three recalls; the low complaint total suggests a relatively quiet ownership record, though the engine-cooling concentration is the area to examine first.

From the factory this vehicle uses a BCI 49 · 850 CCA battery, OE oil filter 079198405E. Note the factory serpentine belt is now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known. Each part links to every other vehicle that shares it, so a part you already stock may fit more of your fleet than you'd expect.

Reliability & federal safety record

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

The 2008 Audi RS4 recorded three complaints and three recalls, whereas the 2004 model year had zero complaints and one recall. Technical service bulletins also rose sharply from 35 in 2004 to 241 in 2008, while investigations remained at zero for both years. This upward trend in reported issues suggests that the 2008 model experienced more field problems than its predecessor within the same generation. Because the data do not specify root causes for the complaints or recalls, any assessment of underlying defects would be speculative. Consequently, the 2008 RS4 appears less favorable from a reliability standpoint, making it a less attractive purchase unless the price adequately compensates for the higher likelihood of service needs.
