From a 1988 SAE test:
“Abrasive engine wear can be substantially reduced
with an increase in filter single pass efficiency. Compared
to a 40 (micron) filter, engine wear was reduced by 50% with 30 (micron) filtration. Likewise, wear was reduced by 70% with 15 (micron)filtration.
“Controlling the abrasive contaminants in the range
of 2 to 22 (micron) in the lube oil is necessary for controlling engine wear.
“The micron rating of a filter, as established in a single
pass efficiency type test, does an excellent job in indicating the filter’s ability to remove abrasive particles in the engine lube oil system.”
Donaldson's web site had info showing apprx 15 (if I recall correctly) degree cold flow temperature advantage of their Endurance filter media (same as Amsoil EA) compared to conventional cellulose filter media.
I use Amsoil EA filters because:
1) higher efficiency = less wear.
2) less flow restriction at startup = less wear.
3) longer effective service life.
