Oil cap...Oil drain plug...Oil filter.
Would you really need a manual to find these three items?
/never worked on a Bug either.
Does the Bug use a spin-on oil filter? It predates the spin-on oil filter, doesn't it?
My understanding is (like I say, I can't buy one so I research)...Bugs don't have regular oil filters (at least not all of them.) Apparently they have an oil "screen" and you take that out and clean it off before putting it back in! They also have a seal you replace before putting the plate back on...
Going from memory here from something I read somewhere...
