2006 Sonata Oil
 

I had my first oil change yesterday at the dealer. It's an '06 Sonata GLS
V6. My owners manual clearly states that I should be using 5w-20 oil for
this engine, but my receipt shows they put in 10w-30. Should I be worried
about this?

I would think that especially for the Winter season, the thinner oil (5w-
20) would be better.

Thanks.
