What happens if I run it on regular unleaded instead of high octane?
The Touareg’s engine management system will retard ignition timing sufficiently to prevent predetonation (knock or ping). This may or may not be noticeable to the average Touareg driver, but theoretically should reduce the performance of the engine. Some have suggested that premium fuel has benefits beyond its octane content. One claimed benefit of premium fuel is that it includes better detergents to prevent the build-up of deposits in the engine’s combustion chamber. It should be noticed that in th e US, Federal law requires that all gasoline contain detergents. According to the AAA (American Automobile Association), it is very rare for premium gasoline to contain a different detergent than regular-grade gasoline from the same manufacturer.
