On my DSE i use one of thease chain type oil filter removers, its like a small bike chain with a handle on on it that has a hook and you put the chain around the top of the filter and put the hook through a link of the chain so when you push on the handle in a anti clockwise direction the chain will thighten and undo the top of the filter, go in your local car shop and you will know what i mean as soon as you see it, its never failed me yet.
