Which oil to use?
Yeah, considering that royal purple was the only brand of motor oil that when tested by an independent lab, FAILED every single test. It also had the worst four ball wear test of ANY oil tested when even some of the cheapest oils tested passed at half the price. There are also tests from a different independant lab comparing various transmission oils from mobil 1, castrol gtx, redline, torco, royal purple, amsoil and a few others.
Yet again, royal purple was the ONLY tranny fluid to FAIL EVERY SINGLE TEST, providing inadequate protection in cold temps, hot temps, it sheared off at pathetic heat levels, and is just plain garbage. I would rather bag up my own feces and mix it with some water and use that than use royal purple. AMSOIL is one of the only oils to pass all tests, and was by far the highest scoring of all of them. It's the best quality lubricant supplier on the market, period. To the OP, use AMSOIL 0W30signature series oil. It's about the best oil money can buy. Royal Purple FTL!
