For most folks...regular, approved/certified/etc engine oil is just fine
But for those who driver HARD, the higher spec of synthetic is worth it...or
for those who are willing to pay and know the difference...it is in both the
base stock spec and the additive package spec. Key or one of the biggies is
the viscosity modifier spec
More pleats is out of context without the depth of those pleats...given the
material is the same.
Pleats are a way to increase the surface area, but a pleat vs another pleat
is incomplete without the depth & material spec (porosity...filter max size
particulate, GPH, etc)
I personally do not like the lower viscosity...especially the first numnber's
viscosity value...but...I live in a warm climate area...even when I skied
a lot, didn't want the lower viscosity oils
Quietness or noise will show up later..when the miles do their thing on
wear of the valve train parts...or...not...
