how it’s possible to show from a post of a custom post type the taxonomy/terms?

that’s the way,
aha aha,
and I like it,
aha aha…

<?php   // Get terms for post
 $terms = get_the_terms( $post->ID , 'oil' );
 // Loop over each item since it's an array
 if ( $terms != null ){
 foreach( $terms as $term ) {
 // Print the name method from $term which is an OBJECT
 print $term->slug ;
 // Get rid of the other data stored in the object, since it's not needed
 unset($term);
 } } ?>
