Synthetic rear end oil ok???

My wife just brought home some Synthetic dif oil instead of the regular stuff. Will this be ok and will it leak past the seals since it is such an old truck??

It is a completly stock 77 K5 Blazer with a 12 bolt rear and Dana 44 front. Can it be used in both axles?

Thanks fellas in advance,
