So I am on my second oil change of QSUD in my Frontier. Was using RP until my stash was used up. I noticed that my oil had a brown/reddish tint to it. It was driving me nuts. I did a UOA with Blackstone and everything was simply perfect.
My whole point of saying all this is the QSUD shows really dark brown/red in about 1k and I guess that is perfectly fine and normal. The RP didn't get a red tint at all, just dark brown.
