[Es2] checked my oil again last night...

Good news! The oil looked completely normal again. No longer frothy or full of bubbles. The other thing is, the dipstick now reads down a half litre, as opposed to over filled by half litre before I started it. This makes sense, since I only filled 4 of its 4.5L capacity. So in the end, I guess what happened is that every drop of oil that I had poured in was sitting in the pan. This caused an over-fill situation, causing the crank shaft to whip the excess oil into a thick foam.
As for the oil pressure warning light, I'm not sure. I haven't had the chance to look into it. But given that the oil pressure gauge reads normal, and that it appears that the oil has circulated to its proper places, I have a feeling that the wires on the sender may be reversed. I won't be taking that lightly though.

Thanks to all of you who offered insight!
