I did my first front/rear diff oil change at 210,000 km on my 2001 BMW E53 4.4i using this full synthetic Penrite Pro Gear 75W-90 even though BMW says diff oil is a lifetime fill. Vehicle drives smoother now. Upon inspection of old drained oil, I could see very small metal particles throughout the diff oil. Don't believe in your car manufacturer's lifetime oil fill recommendations, change your diff oils.

Never disappointed with Penrite oils, they are always the best quality and fairly priced.

I used this in my rear LSD diff on a RG Colorado. Just barely enough to fill after draining the old oil. It’s been ok so far. It’s not cheap so I hope the price is reflected by quality.

The best thing about this oil is that I can find it anywhere. I may choose other oils over this but I change my oils very often so this is fine. I can buy it almost anywhere and at a good price.
Used in my Dmax diffs. Penrite has a great online oil selector for your car.
High quality product. Great for my 4WD. Runs differential very smooth
Correct specification for car, sufficient volume in pack size, have been using Penrite products for 35 years wothout problem, expect the same with this.
The store promotes self service which is great. The staff were great help and I confidently found exactly what I was looking for. You go to a shop like this to buy stuff when you know what your doing. The upside is if you don't know then the staff will help you out. Great service.
Bought this for the rear differential of a 2010 Audi Q5 3.0 tdi which uses 1 litre. Been in the vehicle for 2 weeks and no issues.
penrite best ever oils and great value and super cheap
