Takes me 30-45. I like to let it get a good drain. After I pull the plug I do things like check the levels of other fluids, inspect belts, hoses, etc...pretty much give everything under the hood a real good checking. By the time thats done the engine is quite well drained. Also my filter is not a spin-on type, its in a housing built into the block, so it takes longer to change than a spin-on filter.
