The advise you were given is correct,drive it up on ramps and go in from underneath,Why bother,take it to a Quick Fit type garage and let them do it,by the time you have bought the filter,went to the bother of it all,disposed of the filter and mess,cleaned up,topped the oil level up again it is not worth the bother,save yourself the time and money,look in Yellow Pages for Oil change type garages and go there,I have done loads of them,it aint worth the hassle now.If your determined though,you have to go in from underneath.
