differential axle oil????

[captjanes]

i changed the gears in my 99 tj Dana 30 and Dana M35 from 4.11 to 4.88. i got a few liters of gear oil that i want to get rid of and i was wondering if it was any good to use in my axles??? it is motomaster 75w90 synthethic gear oil. if this is no good can someone recommend a good oil, i am in canada so i would like a oil that i can get in stores like canadian tire,carquest, walmart etc. thanks

Sounds fine...except I'm not a fan of synthetics. Weight is good though.

I've run full synthetics in mine for years without issue. Good weight and I find they synthetics quieten my lockers a bit as a bonus. I say run it.
