The newer electronic machines don't have that many user serviceable parts. I bought a Brother machine a couple of years ago, and found out that the only place one can use oil is in on the wick underneath the bobbin (it's a drop-in bobbin). My embroidery machine, according to the booklet, was oiled enough at the factory and it doesn't require more oiling. It recommends that if it needs servicing to take it to the dealer.
