I just changed the oil in my 09 Sonata and used the Valvoline NexGen 5w20. When I went to pour it in the motor I noticed lots of tiny bubbles in the oil as it drained down the filter...maybe I am paranoid but is this ok? I am pretty sure its ok and I am being real paranoid but you guys can either tell me to drain that stuff out or reassure me...thanks BITOGers!
