I have it in my Explorer right now. It's good stuff. A lot of people don't like it because I guess they picture Valvoline taking nasty used oil and pouring it right back in the new bottles or something. This of course, is NOT the case. The old oil goes through all the same refining steps as regular conventional oil.
Conventional oil is made from crude oil. Remember the BP oil spill? Remember those balls of tar washed up on the beach? Would you put that crap in your engine? Of course not, but after it's refined into nice clean motor oil, you would! My point is, whether it's regular conventional oil or recycled oil, they take nasty, dirty, gross oil and refine it into good clean motor oil. NextGen meets all current API and ILSAC specs and is good stuff. Valvoline wouldn't risk their reputation putting out a crappy horrible product. Use it with confidence.
