Last oil change I did it myself for the first time on my wife’s 06 Honda Odyssey. I used 5w-30, like I use in my Lexus, instead of the recommended 5w-20. This was the first time her car was switched to synthetic Mobil 1, but now the engine sounds louder and not smooth as usual. Did I do something…

I agree with Triedaq. If anything, switching to 5W-30 from 5W-20 would make the engine quieter.
