My manual doesn't have this paragraph but still lists 5W-40, I honestly think it's a fuel economy issue. Remember Hyundai had that MPG fiasco over a year ago, they had to drop the Elantra to 38 from 40MPG. I'm not say it's directly related, but it might have something to do with why the manual was changed. Perhaps they didn't want customers complaining to them about fuel economy.
Straight from Hyundai. Thinner for fuel economy,thicker for protection. Go with the 5W40.
