VW Toureg, and gas requirements

Hi Mary,

It’s only necessary if you want to get the best-possible mileage and performance out of the vehicle. Its engine was designed to deliver optimum performance/efficiency using premium. But you will not cause any harm to it by using regular unleaded. The engine will automatically adjust to safely burn the lower-octane gas.

However, if you use regular unleaded, you may notice a slight drop in gas mileage, as well as a bit less power “all out.” That is, full-throttle acceleration. However, in normal A to B driving, you may not notice any difference at all.
