I just noticed that the clicking/ ticking noise from my engine has increased after changing from Pennzoil semi-synthetic 10W-30 to valvoline conventional 10W-30. The frequency of the noise increases as I accelerate whether in park or while driving. I asked several technicians and mechanics and was told that it would make no difference to engine if swapping oil types. Has anyone else experienced this issue?

 

Oil brand had nothing to do with this. The clicking noise was due to worn rocker arms shafts. Dealership replaced both rocker shaft assemblies under warranty. Clicking noise is now gone!

jesusayalajr2007,

Glad to hear your dealer identified the ticking noise and resolved accordingly under warranty parameters.

 

I have the same sound in my car's engine but I hear this sound once I start the engine or when the engine is cold but when I drive a while and the ngine become warmer the sound is disappearing ,,,,,,I asked many and they told me it is ok and not harming the engine ,,,, but it is not comfortable.
