For USA market engine oil, I looked. Used to be 0W20/5W20, as depicted here. But then changed to 0W20, with verbiage that essentially says you can use 5W20 no more than 50% of the time (sorta).People here do realize these recommendations might change by year, correct? I know the transfer case fluids did. We are taking about a vehicle and engine that has spanned 13 model years.
