Mobil 1 75W90 synthetic OK for diff?

hope so cause it is in there now.

I think the oil in it was all original factory cause the bolt was pretty rusted and stuck.

car is a 90 GXL btw.

this OK for it?

The synthetic stuff? It's great in the differential, but it will chew up the trans thanks to it's high sulfer content. Been there, done that.

I use it in my diff, no problems. If you have a clutch-type LSD (which I don't think the '90 GXL did, but I've been known to be wrong), be sure to add the additive.

Did I miss a meet? Damn, I would have joined in if I knew about it.

I see more people running randomly across the street then squirrels. I'm not suprised, must be something in the air. (ha)

Happy to hear you got the TII running though, wish I had a TII/Auto starter for you. If it was an N/A, I would have taken the starter out of my car for you to get home. (I have a daily that could cart me around for a while. )
