My last oil change I swapped from 5w/30 Valvoline Synthetic Blend to the full Synthetic Mobil One 5w/30. Since the swap I have noticed more piston slap noise when cold. It goes away when warmed up.
It does seem more noticeable since going with the Mobil One. Would it hurt anything to go back to the Valvoline Syn Blend? Is the start up piston slap anything to really worry about?
All my research says no but it is annoying and unnerving at first. I just can't help but think that slap will get worse with every cold start up. So...that's why I'm thinking of going back to the Valvoline and maybe even upping the viscosity to 10w/30. I'm in S.California so don't need to worry about cold temps affecting oil. Thanks for any input.
