Hi,
I have 05 Accord 4 cylynder. After 1500 miles switched to Mobil 1 0W-20 synthetic. I notice that the engine sometimes makes a sound that is best described like the sound you get when you take a toy remote control car and push it around with your hand (without engaging the toy's bateries). The kind of a bit high pitch sound.

Now, I don't know if it is just me imagining things, or is it normal for the new Honda engines to sound a bit high pitch..... :driving: It is very subtle and usually (I think) it is noticable when you accelerate and then let go of the gas pedal (I think?)..... ir it could be that I am just a new owner and a paranoid f.u.k?
