It is quite normal for classic and
vintage cars and bikes to leak some oil during storage (if they don't, it is
probably because there is no oil at all in them).
First Class Additions oil driptrays come
in handy to protect the floor from oil spillage. The driptrays are made of
galvanised steel and neatly finished without any sharp edges. Any oil is
easily removed from the smooth surface with a paper towel.
