Anyone else notice that these engines are louder with anything other than Toyota oil? They're noisy no matter what but with Valvoline 0-20 and Mobil 1 0-20 they are even louder. I will be switching back to Toyota oil at my next oil change. Whoever makes it, makes it to Toyota spec and there does seem to be a difference. BTW I use nothing but OEM filters so the filter has nothing to do with it in this case.
I ran mobil1 for a while, then got some penzoil high mileage on sale. Engine was noticeably more quiet on the pennzoil. I then switched back to mobil1 and have been running it for last few OCI. I'm tempted to try the pennzoil again or the toyota oil again to see if i notice a difference after being used to running mobil1 for a while.
