2009 vs 2010 MT Fluid and Rr Diff Requirements

davidyan · 12-19-2009, 01:30 AM

Was looking at the recommended fluids and noticed that in the 09 owners manual for:

6spd MT: the recommended fluid is either GL4 75w-85 or GL4 75w90
Rear Diff: GL 5 80w90

In the 2010:

6spd MT: 75w85 GL4
Rear Diff: 75w-90

very small differences in recommendations, wonder why...

Well I decided to ask Nissan the question only to get the standard evasive answer... (pasted below).

Based on that, going forward, I will probably use the weights recommended in the 2010 manual. I don't think it would make much of a difference but decided to ask.

This is interesting because when I called Nissan about the difference in fluid recommendations, they told me the owner's manual is only recommended items but the dealers know best. Therefore the logic says to go with an 80W-90. Furthermore, dealers dont carry any Nissan 75W-90 oils at all, especially not a synthetic differential fluid.

I'm going with my manual too and putting in 75W-90 synthetic fluid. I figure that they had a reason for changing this, even if the customer service folks running a phone line dont know what it is.

they also told you that for every 3000miles oil change is required because your oil turns black?

I'd use the 2010 recommendations...

What's evasive? They told you straight out what they must recommend.
