It cleans off any and all deposits that increase friction and decrease mileage. Especially in hydraulic lifter cars.

Bearing wear? The only bearings that were bad were on the balance shafts. That says something. How would a bit more vibration hurt my remaining bearings, especially with increased oil pressure? I'm calling BS on the "more wear from vibration" theory. Diesels vibrate like crazy. My inline truck motor vibrates enough to shake the mirrors at idle. I'm not worried about the tiny amount of vibration hurting the rav. I can barely feel it and nobody else can even tell it's there.
