We have run Qualifying Driven oil in the Challenger Rear with no issues and a 4.88 until I went to 3470+ lbs. At 3250 no issues for 2 season. At 3470 we hurt gears. They are not Pro Gears and its only an 8 3/4.....so keep that in mind.
Switch to the Driven's Speedway Synthetic oil in Challenger and have always ran in COPO with no issues. Its VERY light.....
I do break in for 3-4 passes with No Synthetic Driven Break in or Torco oil from Mark Williams.
As far as an A to B to A test - never done - doesn't matter since I won't run a light weight non synthetic in the rear or trans anyway - we have enough other **** to test when we go out!
