I am in Ohio, but I only drive the car from April to November. Aren't both of those 75 weight cold though, so shouldn't they be the same viscosity cold?

75w90 is a bit thinner than 75w110 and 75w140 in cold temps, but still within range. The pour points are fairly close, and at -51 degrees F you should be plenty safe, particularly between April and November.

My LE1605 SAE110 is much worse in terms of cold temp operation, it gets crazy thick. Even at room temp I have to heat it up in hot water to get it flowing into my diff quicker. I think the pour point of it is in the high -20's, but I would expect that it would be almost a solid at that point , lol.

Crap I'm sorry I had a blonde moment. Of course the 75w indicates cold weight durr... lol sorry for the confusion.

I remember some type of diff fluid though that someone put in their car and they had to microwave it at room temperature to get it to flow. Otherwise it was like a jelly.
