Long story short, the manual says I need some SAE 90 Gear Oil for my 4 wheel drive civic's rear diff. Looked everywhere for it.. Autozone, Walmart and came up short with only hybrid gear oil such as 75w-90sae and **** like that. Anybody know where I can find some straight SAE 90 oil?

 

This might be a long shot, but what about Honda?

 

Preposterous.

Go to the place that sells items specific to Honda vehicles? I say he hits a dead end there...
