Recycled oil

I never had an engine failure with Dino oil either, and I must have put a half million miles on various cars with the stuff. Had a 71 Challenger (still kicking myself for selling it) that had 217,000 miles on it when I sold it. That being said, I've been using synthetics, including trans, transfer case and differentials, for more than another half a million miles on various cars since the early 90s. A Mobil 1 change costs me less than $25 for the oil on my daily drivers and about $30 for my tv. I believe it is the best oil for me so I use it. To each their own, right?
