Who here has switched from Pennzoil Platinum to Mobil 1?

I've used both. At one time Mobil 1 in 2 cars and PP in the other 2. I notice no difference between any of them. I really like the Mobil 1 0w30 oil though. One of my cars just recently had a catastrophic engine failure. It had Pennzoil Platinum 5w30 at the time. Though I know it had absolutely nothing to do with the oil in it. It was rebuilt by an engine re-builder not too long ago and I think it has something to do with that. I need to tow it to the house and tear it down.

Switching from PP to M1 made my 4G94 Lancer louder but that was a good thing because I like the way it sounds. =)
