Royal Purple diesel oil

[sredish]

Local shop here started carrying / pushing Royal Purple. They have a 15/40 and a 5/40 summer blend, both synthetic. Anyone use it or have experience with it? I'll probably start using it as it's about the same price as the Rotella 5/40 syn. I've been running, just wanted some opinions.

I race with a few guy"s that use it in there 406 race engines. they say it works fine,if i remember right it was a little pricey so i have stuck with valvoline.
