Ok I'm all set to do my diff oil change this weekend, but have a question. I purchased 3L of 75w-90 synthetic oil for the rear and already had a new 4.4L jug of 80w-90 for the front. Looks like the rear only needs 1.6L and the front .85L. So should I use the synthetic 75-90 in front and rear as i will have enough for both or should I stick with the regular 80w-90 for the front and keep the extra of each around for the next changed?

up to you really. I went with 75w90 synthetic in the front when I did mine. going to do the same when I change it again in a couple months (at 90k)

Shouldn't matter. The W90 number is far more important than the 75 or 80.
