Oil smell test ever hear of it ever use it.
Filters only filter out solid particulates filter size doesn't matter. No filter of any size
filters diluted contaminates courtesy of EGR or PCV, smell gas on dipstick or from drain pan
your running oil too long. Oil diluted by condensed gas vapors is not good.
Couple times I've tried Syn oil/milage my engine/driving habits smell telling a bad idea.
Works same with Rotella T4 10w30 D3 3-4k mi interval no smell I'm good works for me.
Milage ratings - Lab - new engine - controlled conditions - not real world.
