Gritz, I was surprised at the 0W-20 in our 2014 Altima. Have used Mobil 1 from start, now over 100,000 miles with no issue. I am not against Synthetics when it is specified by manufacturer.
Have a 2007 Suburban with 5.3 LS engine. I tried full synthetic and synthetic blend, both used oil rapidly. Normal oil usage was a half quart every 2,000 miles, both synthetics were more than double usage and no leaks. It has over 140,000 now on convenntional GTX.
