gear oil specs - follow up to my last post

That's another question I had. About the type of gear oil to use. The guy at Auto Zone told me that 75W-90 was the proper type, but all they had was 80W-90 so I just used that. Unfortunately, the quart bottle I bought wasn't enough to fill the pumpkin. My dad has another bottle of 85W-140 or something like that sitting in the garage. Would it be ok to use some of that to top off the pumpkin, or should I go buy some more 80W? (Exactly how much is suggested in the specifications for a Dana 35? 1.5 quarts?)

I never like to mix oil viscosity, you don't know what you've ended up with. And I never mix brands either, different brands have different additives, paranoia, but, I'd hate to be the one to find out that the additives of the 2 differnet brands caused an adverse chemical reaction. Make another trip to the store!

Ok, I think you're right. I'm just going to go buy some more. Do I just fill the pumpkin until oil starts coming back out of the fill hole?

Does your metal plug have a square recess in it? BTW 75W90 is out there, you just have to look real hard. I believe Trak Auto sells it. It's where I got mine(the only place I could find it). But I hate to shop there and they are going out of buisness in the midwest at least.

My drain plug was rubber. I was only able to get it out after completely removing the differential cover, holding it steady in my lap, and using a punch to force the plug out.

Yep, just keep pouring it in until it starts to come out the fill hole.
