Great satisfaction seeing as the rain didn't arrive, all the filters changed and it's easy but I was sent the wrong oil filter so having drained the oil and removed the filter bowl it was obvious it wasn't going in, so I refitted the old filter and put fresh oil in. The filter sent had a plastic stalk sticking out of the top and the diameter was bigger than the plastic bowl, so I've contacted the vendor.... When the right one arrives is it feasible to change the filter without draining the oil?
