Not Ranked
Around here, Royal Purple, GM, and Pennzoil are readily available. I'v tried them all. The Pennzoil made for hard shifts and missed shifts. I drained that out after one race week end.
The other two seemed to be about the same, couldn't really tell the difference. I use GM, because it's a little bit cheaper.
