New gear swap!!! Synthetic or regular gear oil???
Will using synthetic gear oil hurt a new gear set? Do I need to use regular gear oil for break in?
I am putting richmond 3.73's on my stock posi unit. Will the synthetic gear oil be ok from the get go?
thanks.

I wouldn't break in a gearset with synthetic, read why on the other thread.

Personally I don't think the gears will thinks about it twice if you put non-synthetic in. When I did mine I just put in the regular dino oil in, and they have been fine ever since.

You make a good point, but I think I will use synthetic.

True, it is a different question, but the other thread has digressed into a debate on much the same subject : )
My stance, GL5 for the first 500, then Amsoil synthetic. GM posi addative if needed. I tend to run lockers, so this usually isn't an issue for me.
