I run 90W120 normal oil in my diffs like Valvoline of similar with a big diff cooler. Keep it cool and the non-synthetic work great and are quiet. On a side note, I have had C&R build and dyno my last two diff. It is great. They are set up correctly, they are quiet and do not require break in. I have tried synthetics and they have always been noisy.

Thank you. Im about to start adding fluids in my car. Its getting close. I was going to use some driven br30 break in oil and then switch to ls30 for the engine.

As far as the t56 goes i just started researching it.

The rear diff i was told to use reg diff oil but dse was saying they use driven 75w90 gear oil which is synthetic. Just trying to fig out why some use 75w90 and others use diff weight.
