Of course :)
But is there any such thing as Regular?
It varies so much from country to country, in USA they run on mostly 91 octane and in Europe we use nothing less than 95.
The higher octane fuels tend to give you better fuel consumption and better perfomance, so just put the best fuel you can in :)
I try and use 97-98 in a 1.8T and the car prefers it.
