Till today I was sure that 0w20 is only available in a full synthetic flavor.
Found a blend today @ Walmart
https://www.walmart.com/ip/Castrol-GTX-ULTRACLEAN-0W-20-Synthetic-Blend-Motor-Oil-5-Quarts/752307232
So I wonder, is it really syn blend or do they just bottle 0w20 synthetic for marketing/PR purposes?
