Has anyone tried the Royal Purple Max-Cycle oil? What are the results? $:-\$

I haven't seen any ASTM test results on Royal Purple, I have used their limited slip gear lube in my truck, like it a lot. A lot of the people here use Mobil1, Redline and Amsoil, all have great ASTM ratings.

I added this after the original post.

Here's a comparison with ASTM ratings between Amsoil, Royal Purple, and other oils, it's a Amsoil site, but the test info should be correct.

Users of our gas turbine engines had a problem with Royal Purple. I have been using www.redlineoil.com for many years in my motorcycles, Mobil 1 in the cars and trucks.

I use the RP Max Cycle in my engine and primary. 7,000 miles on this bike and only issue so far was warranty of the head gaskets which had nothing to do with the oil. I have a buddy who turned me on to it and has a 98 Softail with over 30k miles on it with RP and a 2007 Street Glide with over 10k miles and lots of engine work. He has never had a problem.
I have Mobil1 in my Street Bob and will switching over to RP when it is time to change.
I think you will like it.
