Audi Q5: Gasoline additives

Applies to vehicles: with gasoline engine

A major concern among many auto manufacturers is carbon deposit build-up caused by the type of gasoline you use.

Although gasoline grades differ from one manufacturer to another, they have certain things in common. All gasoline grades contain substances that can cause deposits to collect on vital engine parts, such as fuel injectors and intake valves. Although most gasoline brands include additives to keep engine and fuel systems clean, they are not equally effective.

Audi recommends using TOP TIER Detergent Gasoline. For more information on TOP TIER Detergent Gasoline, please go to the official website (www.toptiergas.com).

After an extended period of using inadequate fuels, built-up carbon deposits can rob your engine of peak performance.

Note

  • Damage or malfunction due to poor fuel quality is not covered by the Audi New Vehicle Limited Warranty.
  • Do not add aftermarket fuel additive products to your fuel tank.
