A Conversation for How to Change an Oil Filter

If the engine oil is old or there are signs of deposits in the oil it is worth flushing the engine with flushing oil. It always pays, in any case, to turn the engine over just once while draining to get out as much oil as possible, but *DON'T* leave it running!

Another point to mention is that the engine drains better if the oil is warm (although not hot - see point about scalding.)

Some engine filler caps have a wire mesh air filter. If you have one of these you should rinse it in some solvent and soak it in clean engine oil before replacing it.

heres a tip disconnect the ht lead from the coil (providing it isnt a diesel engine) and this should stop the engine from starting also waste oil can also be used as a kreosote for wooden fences

I have heard of people turning the motor in an attempt to get the remaining oil, and thus providing a clean environment for the new oil. I was even told once about a guy who would drain the oil, start the motor and rev it full throttle once to clear it.
Personally I don't think it's necessary to do either, there is ususlly some oil trapped in the nooks and crannies that would be nearly impossible to get out. I know my own car's drain plug does not even fully drain the sump. A clean filter should pick up debris of any consequence, and turning the engine with little or no oil could cause more damage than it would be worth.

If your engine is making the oil that dirty that you've absolutely got to flush out every last drop, I would recommend keeping the oil and changing the car. smiley - biggrin
