Pros & Cons
Pros
Top quality differential lubricant. Zero noises, zero leaks, and holding strong. Viscosity feels very good.
Good service, as advertised. Great product. I run this is everything i own always had good luck with it.
Cons
Title says 1 quart, 6 pack but only received one single quart bottle. Don't use in a toyota requiring gl-4.
Highlights
Quality
Product arrive safe and sound it is as described perfectly shipped nice new clean product
I also love the hand pump that comes with the bottle
40k miles came and passed so i did a transmission drain and fill with the royal purple product and its a night and day difference
Price
The pump was well worth the extra cost
Not sure if its worth the extra cost
Packaging/appearance
Just wish i had remembered to get a pump the fill holes on the front diff can be an issue
Competitiveness
Cant go wrong with any of the top brands
I believe the previous owner used 5w30 motor oil
Pricey but cheaper than a new car

Thought this would be a perfect fit because of the combo but you have to hold it on the top as it just sits there

I own a 2002 trans am mileage 44678 rear was noisy so i began the process removing the factory cover fluid and noticed fluid was clean my concern was it looked thin i mean light weigh i think it was the wrong weight and cheap inferior product i clean the area and checked all gears for wear or excess wear all good replaced with a updated cover called perfect launch all aluminum cover with drain and fill ports added royal purple max 75 90 and added red line lsd additive

If you are doing a diff or tcase fluid swap pay the extra dollars for the pump that attaches to your gear oil bottles

Per mazda the gear oil has to be gl4 safe this is
Posted by a reviewer on Amazon
It needs to be for hypoid gears and contain the right additives this does
