Audi RS4 Cabriolet Engine Oil Specs

The Audi RS4 Cabriolet was produced from 2008 to 2008. This model typically uses 5W-40 full synthetic engine oil — a specification common to most Audi RS4-series vehicles.

Selecting the correct oil viscosity for your Audi RS4 Cabriolet is essential. Using a grade that is too thin reduces protection at operating temperature, while too thick an oil impairs cold-start flow and reduces fuel economy. Always match the exact grade shown for your specific model year.

The recommended oil change interval for the Audi RS4 Cabriolet is every 5,000 miles or 6 months. Under severe driving conditions — track use, towing, or frequent cold starts — shorten this interval by 25–30%.

When servicing your Audi RS4 Cabriolet, always replace the oil filter at every oil change. Using a premium filter — such as the Mann or Mahle filters specified for European engines — ensures proper oil pressure.

Oil change costs for the Audi RS4 Cabriolet at a US dealership or independent European specialist typically range from $120 to $200 for a full synthetic service. DIY oil changes cost approximately $30–$65 in parts (oil + filter) and take about 30 minutes with the right tools.

Always consult your vehicle's owner's manual to confirm the exact specification for your specific trim and engine variant, as some Audi RS4 Cabriolet configurations may have different requirements.
