MOBIL DELVAC 75W-90 Synthetic Gear Oil - 38 lb Pail for Heavy-Duty Trucks & Commercial Vehicles

I bought this to change the rear differential fluid in my motorhome. When it arrived, I carefully inspected the information on the labels, and found everything to show that this is genuine Mobil Delvac gear oil. Mobil Delvac makes very good gear oils. Being a Mobil Delvac fully synthetic gear oil, I will not have to change the fluid in my differential for a very long time.
