Fuel used in fast and furious car, especially Dominic terreros car...

I store things away on shelves with doors. Three groups of three I always have in me: The first three is a taxi. The next three contains rubbish. The last three can catch you. What am I ?

Without me, you won't get far Traveling by plane or old train car. I may just be paper, But with me you're safer From a metro city guard.

I sit around the castle, and make reaching the front door inconvenient.

Where the path meets its end, A steadfast friend, not one to bend. Keeps the wanderers' pace in place, A gentle wall, a quiet space.
