I'm new so excuse if this has been discussed here elsewhere, probably ad naseum. In easy-to-understand layman's terms, what is the difference between these two? I see the 0 oil advertised by M1 and others as "for use where 0w-20 or 5w-20 are recommended".
Is that true? Can you really just substitute the 0 for the 5 oil? For reference I live in Pittsburgh and my car is garaged. Occasionally my wife will come out from work and her Lexus RX-330 will have been sitting outside in 0-20 degrees for 8 hours. And in the summer we MIGHT get a stretch of 90-95 degree days. But that's about as extreme as it gets. Most driving is city.
