Thanks for reposting that TSB, I wasn't aware.
What oil meets the ACEA A5/B5 spec in a 5w40? Feels like Hyundai has gone out of their way to make it really difficult to follow their own recommendations...
I don't believe there are any that meet that spec. I haven't bothered to worry about it. I just use Motul 5w40 and an OEM filter and call it a day.
