I know Jiffy-lube is full of but this guy over there showed me that there is a rear differential fluid that needs to be changed (according to the computer every 3000 miles)...I wasnt aware of this fluid, and it doesnt seem like the previous owner changed it....they also told me that it needs synthetic oil....
My car has 50k miles on it...do i need to change this fluid? every how many miles?
