Royal Purple Oil/Filter

[GQM45s]

Does anyone else in here use Royal Purple? I have been using it since i first got my car and I love it, better MPG(slightly, but still better) and it idles alot lower than most oils i used in the past.

I use the Royal Purple Oil 5W-30 and the Filter 10-2867

Everyone else that use it, like it alot?

Not sure about Royal Purple.

I use Castrol after reading massive oil analysis post on VQ35DE on another forum. If I recall, Royal Purple wasn't as good as people through it to be based on used oil analysis. This was on VQ35DE and VQ35HR engines
