So, I have always run Shell V-Power in my Accord, yes I know the octane level will not give ANY benefit at all, I just like the fact that V-Power has extra cleaning agents, anyway, I recently started running regular gas from shell (89 octane) and I have noticed the tick went away....is there any way at all this could be related? It makes no since to me, but Ive listened for the tick every time I start my car (often) and It has not ticked one time since the regular gas.
