If you can not unscrew the filter, call your neighbor – maybe his fingers stronger. In this case, be sure to tell him that you think his arm is very strong. This will add him to enthusiasm. If a neighbor does not help you able, look at his friends time to loosen oil filters. If this fails, the filter will remove with a hammer and chisel.
This is the first way. Beat should be along the edges of the filter (assuming that the filter has shape of a cylinder, then here and an edge filter, called the base of the cylinder). If the metal breaks, it is necessary to replace a chisel to some blunt instrument, and again try to hit stronut filter away. This "stupid" tool can serve a large flat file. Shank him (by him will hit the fall of the hammer) for greater rigidity strikes should whittle away at Emery. The second way – to sharpen a flathead screwdriver and the side punch filter.
Then, using the same screwdriver, using it as a lever to turn off a half-turn filter. If he unscrewed at least a half-turn, continue to have, most likely, it will be possible to turn off your hands. When the latter two methods unscrewing the filter it comes in complete disrepair, since it appeared a hole, but there is one more "barbaric" way in which the filter is integral, albeit badly crumpled. For this we need to have good "montazhki" with integral faces at the ends and at least a good persistence. End "montazhki" rests on the edge of the base oil filter (where it has a collar) or in its upper edge, then "montazhku" turn up until it rested in something. Thus, "montazhka" plays the role of a lever, the end of which scrape the edge filter. If this edge with a blunt chisel to make a dent, even a little dull "montazhka" catch hold of the filter housing. End "montazhki" naturally slips off, but after 5-15 minutes. such "soskryabyvaniya" filter is typically "rent". Experienced auto mechanic in this way can unscrew the filter for 2-3 minutes. Before screwing the new filter it is desirable to at least half fill with fresh oil, the oil impregnated filter element. Then, after starting the engine oil filter is rapidly filled, and the oil pipeline immediately rise pressure. It is also desirable lubricated sealing gum on the filter. In this case, tightening the filter arms, but in a different way to do this can not be easily achieved by tightness in planting the filter. Source All of oils and greases
