I bought 5 quarts of Porsche 75w90 diff fluid about 3 years ago. Sold the car and havebeen staring at the fluid for the last 3 years. According to the bottle it expired in 2017 and was made in 2015. I don't put much stock in that since the service interval fof the fluid in the diff is 12 years or 120,000 miles.
Anyway, I have a ford excursion and want to swap out the front diff fluid. It calls for a 75w90 GL 5
Can I use the Porsche stuff in it? I don't know what the GL rating of it is or where to find it.
