Tuneup for your Superfast Matchbox car

This is obviously meant for one of the early 70's Matchbox 1-75 range of cars, but what on earth is it for ? How do you use the tuneup oil ? Pop the tiny 1:87 hood and fumble for an equally tiny dipstick ? How on earth do you use the track wax ? Mr Myagi style perhaps ? And the brush ?
