The Volkswagen New Beetle Turbo 1.8L engine requires regular unleaded gasoline with a minimum octane rating of 91.
* Using a lower octane fuel can cause engine knocking and damage.
* Using a higher octane fuel than required will not provide any benefit and may actually reduce engine performance.
* Fuel Filter:
Replace the fuel filter every 30,000 miles (48,000 km) or as needed.
* Fuel Injector Cleaning:
Have the fuel injectors cleaned every 60,000 miles (97,000 km) or as needed.
* Fuel System Treatment:
Add a fuel system treatment to the fuel tank every 3,000 miles (4,800 km) to help keep the fuel system clean and free of deposits.
* Avoid using gas stations that sell low-quality gasoline.
* If you are storing your vehicle for an extended period, add a fuel stabilizer to the fuel tank to help prevent the gasoline from going stale.
* Do not overfill the fuel tank. This can cause the fuel to overflow and leak into the engine compartment, which can be a fire hazard.
