Bit like my derv oil after 6 months and 2 thousand odd miles.
I use a sucker to get the oil out, and after 4 oil changes done by the sucker, take it to a garage and let them drop the oil and put a new filter on.
I am getting too old to clamber about under the car, my excuse is that we live on a hill and I dont trust jacks/axel stands, if they arnt on the level.
