I asked a local race axle specialist how much oil to put in, and was told 4 quarts, but I think this is going to fill the axle housing above the level of the axle tubes, and I am wondering if this is too full and a lot of oil is going to come out the breather when we run it on the track. Can anyone tell me how to get the proper oil level in a GTS axle? It has the Tex racing differential with integral oil pump and seals that block off the axle tubes near the center section.

3 quarts
