Changing the oil from my LSD English axel.
Got the oil and LSD additive and Sython pump kit to drain.

How much LSD additive to add to the oil ?

is of best to mix it then refill or poor in one at a time ?

I'm guessing the diff will hold just over a litre of oil.

Cheers
Nick

Does anyone have any ideas ?

i just bought a diff oil that was meant for plate diffs.

i think this was the one, http://www.opieoils.co.uk/p-60255-millers-oils-crx-ls-80w-90-competition-semi-synthetic-transmission-oil.aspx
