I am an Amsoil Signature Series user in the vehicles I care most about. However, the engines of some exhibit piston slap until fully warmed up, especially during the colder climate. Reading through the reviews (mostly on Amazon) for Schaeffer's oil, almost all reviews rave about the engine being quieter. I know there is a high micro-moly content and quality components, but is this Schaeffer's quietness for real? If so, I am tempted to switch.
When I went from factory fill to Amsoil I noticed a huge improvement in quietness. I know some of this was due to engine break-in, but the oil did make a difference. I am trying to reach the next level of a quieter engine. Can anyone support these reviews that I am reading?
The engines the exhibit the most amount of noise: piston slap and valvetrain are:
2018 Toyota 4Runner 1GR-FE
2007 Honda Accord K24A8
2003 Corvette Z06 LS6
