I'm very sure this has been covered but what gear lubes are people putting in the front and rear diffs. Thanks for the info

I believe nissan specs call for 75-140 syn oil...

correct me if I am wrong...

I think the 75W-90 is recommended for the front and 75W-140 for the rear.

I have a 2WD 06 that just turned 30k - mostly highway miles and i never tow anything. The rear diff fluid looked like new when I changed it and the magnetic drain plug had minimal munge on it. I refilled with Royal Purple 75W-140 full synthetic and seem to be getting slightly better gas mileage. I need more time to verify but it seems to be .2 to .3 mpg better. I have never used Royal Purple products and was leery of them. It was in stock at NAPA for $10.99/liter and I figured if they sold it, it must be OK. Valvoline equivalent was $12.99/liter.

I changed my diff oil a couple days ago at 1200 miles. It looked dirty, real cloudy about 1/3" of crud stuck to the magnet. I recommend changing it for the first time at very low miles. The oil was not broke down just dirty.
