When the majority of driving is done on the highway, Audi oil intervals can be anywhere from 6,000-15,000 miles 。
With race and spirited driving conditions, it's recommended to change the oil more frequently. Typically the oil change interval is around 1,500-4,000 miles, or after each race competition。
An abundance of short distance city driving accelerates contamination of the Audi motor oil and shortens oil change intervals. Conversely, running the engine for longer distances at normal operating temperatures (for 20 minutes or longer) results in cleaner motor oil and longer oil change intervals. Blauparts recommends a shorter Audi oil change interval from 3,000-5,000 miles for short distance city drivers. Shorter oil change intervals should help extend your engine's life, making the best out of poor driving conditions.
