Sump plugs

I want to have a go at changing the oil on my Mitsubishi old banger. Givenit's my first time doing, it might be sensible to lay up some supplies justin case something goes wrong...I've been thinking about getting a spare sump plug and washer just in case,but I'm rather confused by the range. AFAICS sump plugs are basically justa bolt, with potentially an unusually shaped end. By looking around thereseem to be a few different sizes or threads.That much I understand. But why are some people selling plugs for specificmodels of car? Don't manufacturers use the same style of plug in all oftheir models? I need order one - probably eBay if I can as I don't want topay a fortune for postage. Usually Mitsubishi isn't listed, which makes ita pain. Is there a big cross reference list somewhere? My workshop manualis silent on the subject. I /think/ Mitsubishi is usually 14mm x 1.5 thread- can I just buy any old sump plug of those dimensions or will there bemodel-specific stuff (like some models need a different size or head, ashorter bore or something like that?)And what's the difference between washers? I can find, at least, steel,copper, fibre, nylon and rubber. Which to choose?ThanksTheo

My local dealer certainly does.

It's a soft plastic surface. I wouldn't have thought any sort of sealant of much value there.

Problem is that the late ford sump nuts incorporate an o ring, it is glued in, I started picking one out once and gave up and fitted a new plug ! They can be re-used quite a few times and if you CBA you could change the o ring I expect.
