There are numerous discussions on 5W20 vs. 0W20 motor oil. It seems to me that the common consensus is that 0W20 is better than 5W20 for engine lubrication, at least not worse, for oils of the same brand.
What has puzzled me is why some cars (slightly older models) call for 5W20 in their user's manuals, not 0W20? I suspect (in another thread) it was due to availability and price sometime ago, but never get it explained or confirmed. Hope someone can give a more concrete answer.
I sent an email to Honda for their Gen 2 Odyssey, but got a useless answer something like "Our engineering team determined that 5W20 is the oil you should use".
