It is possible to change the oil/filter on most cars, however you would need a suitable area (ie a pit or ramp) so that you can get underneath the car. You would also need a receptacle to collect the old oil, plus a process to dispose of the old oil. We do not have the definitive details of each and every car and so would suggest you obtain a workshop manual (you can get one from "emanualonline.com for £9.99). Or, if you don't have the facilities, then you could buy your own oil and filter and ask your local garage to do the job. It shouldn't be that expensive.
