. Maybe you meant that you have to buy 3 liters at a time, which is indeed true.
I actually used about 1.4L after draining it overnight, and spilling a little when full (can't prevent that). Bottom line is you can do TWO differential oil changes with 3 liters, but since most dealers won't use the expensive oil unless squealing is severe, I opted to use Royal Purple Maxgear 75/140 instead (same spec as stock), and problem solved. And yes, I do my own maintenance
Thanks. Yes, I meant to say that the lube comes in half liter bottles, and 3 are needed. And I see each liter now costs about $40.00 each.
