I had a similar question about my wife’s Sonata, but would like to emphasize that the oil is NOT sludge – it’s topped off and it looks like it was just changed yesterday.
The car is almost 3 years old and has about 6K miles on it, and every time I pop the hood to refill the wiper fluid the oil level is unchanged and is completely clear of any contaminants. So even though the oil looks fine I should still be changing it?
