I need your opinions. I am thinking of switching from M1 5w-30 to Rotella T Syn 5W-40. Hoping the motor will quiet down and that Rotella actually is better on the wear side of things. My OCI is 5K miles.
Is this oil too heavy for my 2004 Subaru Outback 4 cylinder, which recommends 5W-30?
I live in San Diego.
Appreciate any input.
Thanks
