Re: I wanna run royal purple in everything
5w30 Royal will run 9-11$ a qt depending where you buy. Gear oil is 20$ a qt. My front and rear dif take 2 qts each totaling 4 qts. I prefer to change my oil at 5k miles. Oil can be changed up to 10k miles if you prefer, but the filter needs to be changed @ 5k, and oil topped off.
Not sure about power steering as I don't run that in my truck, or royal purple oil filter.
