I have read articles on how Royal Purple has added as much as 5 HP just by adding the oil. I have run Royal Purple in my Eng, Trans, and Diff for the last year. Though I can't say that I noticed a HP increase, I continue to use it just for the fact that it's a top quality synthetic. Any synthetic oil is better than conventional oil.
