I have an 02 RS 4EAT 140k, and decided I should check the front diff oil level since i just had the rear oil replaced with 75w90 Valvoline Synthetic. The level was on the "low" side so I refilled it with the extra Valvoline I had left from the rear (bought 2 bottles). After refilling, I realized that the front is supposed to use 80w90. Will topping off the front diff with 75w90 hurt anything, or should i drain and refill with 80w? Thanks
