1.9lt turbo. Does this model require premium gas?

You only need gas rated at 87 octane. If you live in the mountains at a higher elevation you can get by with useing 85 octane fuel. Check with the owners manual for the recomended grade if that grade works for you without the engine knocking, any higher grade would just me an unnecessary waste of money.
