Some of these guys are nut cases. 0-20w oil is 0-20w oil... now depending on quality will depend on how quick the oil breaks down... amongst other things, but a better quality oil is the only thing I can think of with what some of these guys are talking about... and only a UOA with different oils under same driving conditions will yield the proper results. Change your oil every 3mo or 3000 miles is what they used to teach, and thats what I'm sticking with... synthetic or not... 3mo3000mi is what works for me.
