Curious as to how spotless Castrol Edge keeps engines vs Mobil 1. I have used mobil 1 in several different applications and can say it does a great job at keeping engine internals spotless.
Considering EDGE 5w30 in my lexus IS250, but have never really seen or heard much evidence of it's ability to keep an engine clean to Mobil 1 standards.
