    Looks like it, its pretty cloudy. I hope that white crud was in the bottle before you drained the oil

    I doubt it is coolant, but it probably is water. If you run a catch can it could have got water in it after a rain or wash and then sucked in the gearbox from there.

    creamy oil

    Is that white stuff leftover from the plastic bottle you used or your engine?

    My experience with this is most common is to get gas in the bottom end from petcock not shutting off and carbs overflowwing into catch bottle. That doesn't 'look' like gas in the oil, but... Do you use a catch bottle? I assume not since you are on the street.

    Do you run coolant or water?

    before i jump into any conclusion. was the bottle free of water before you pour the oil into it ? if it was dry, probably OZRS is right.

    looks like some sort of metallic filings to me! but it might just have already been in the bottle!

    stick yer finger into the crud and rub it between youre fingers if it feels like grinding paste then its part of you're gearbox metal!

    maybe it's liquid from the cooling system
    check the water pump's seal
