Cold Oil, Oil Change

And it freaks you out when you undo the filler plug and over half a litre of oil drains out and it's a grey sort of colour!

Happened the first time I serviced the front diff on a Defender a very long time ago.
The swivels had been overfilled with One Shot (really clever deleting the level plug Land Rover!) And so had blown through to the diff compartment.

When things don't work out as they should, its not easy to refill back through the drain hole. [bighmmm]

I find it better to just loosen the filler plug and leave it in place so that you don't get a big "Gush" of oil all over your hand when you take the drain plug out [thumbsupbig]

yep if there's particles there and you stir up the oil and drain it you can pull them a lot of them out with the oil.
if you leave the oil to sit the particles will settle to the bottom. the thinner the oil the faster they'll settle.

When we take oil samples from transmissions they are always running when we do it so we see the oil that's in circulation.
