Good base oil and synthetic
Grabbed a few bottles for Jeep differentials. RP is always rated highly and since I do my own work I can afford to spend a few extra bucks on the best lubricants. No issues and will continue to use moving forward.

High quality oil
This is probably the highest-rated oil on the internet. I searched for a rear-end gear lube oil when changing the oil in my 2008 truck axle with 200k miles. Pro Tip: Order the pump too. It makes refilling the rear axle super easy.

It's a little more expensive than most oils, but worth every penny as you cannot beat the quality.
