Note in the ranking list that the conventional Castrol GTX 5W-20 is ranked #20 and the RP synthetic 5W-20 API SN is ranked #32. Why would someone pay more for less?
Those tests do not directly relate to a running engine,sorry.
if you use some of those oils that score well in those "tests" in an actual high performance engine,they will not do as well as some of those that do not score very well.
PERIOD.
It may not be that they have high levels of zinc, it may not be because they have high levels of whatever. It IS because they do a better job of lubricating an actual RUNNING ENGINE.
If you really want to test oil you need to do tests on actual engines! You people that rely on what you read on the "internet" as truth,need an eye opener.Goto an engine shop,see what they use,etc. Get some reliable data and go from there in your oil choices.
No where in my statement did I imply that all engine shops use is Royal Purple,way to twist on my words,not cool at all.
I meant to go check out what engine builder like and recommend for your particular application.
You guys wanna hate,thats fine. I've seen what this oil is capable of in street and race engines. I was warned this forum is bad for any Royal Purple related topics,it is what it is.
I use Amsoil,Royal Purple,and Valvoline in our applications currently.
I am using R.P. 0w20 in my Civic SI I love it. Will continue.
When you go to car meets and talk to enthusiasts....you find ALOT of folks using R.P. And in far more $$ and far more high end cars than mine. Top Gear on BBC even talked about the desire to get it in europe easier than it is now.
