Thanks for the clarification.

The interval you are referring to are for both s4 and rs4 saki?

its borderline excessive but for the cost, why not. We spend a premium of about 10% of annual fuel costs (that’s 100 to 400 dollars a year) to run 93 or 94 when 91 will do. Why? We want top performance.

Same reason I do my fuel filter pretty regularly
