Actually, what I meant was that hen they had their comparative data sheet available, the mojority of it looked pretty ho hum...bar a couple of jewels...nothing wrong with supertech...and I wouldn't have paid the RP penalty for (particularly e.g.) the 5W30
Correct me if I am wrong, but, presently, is most or all Royal Purple motor oil API SN now, and their last redeeming motor oil perhaps their API SL 0W-40, containing the words Synerlec? If API SN, I would agree it probably is formulated most the same as everything else to get that API SN rating and nothing special other than the color..
