There are plenty of guys on here with a lot of miles on their turbo- these are the guys who removed the banjo filter.
Almost 211k on the original oil feed lines, motor & VF-40 turbo. 15k OCI, custom stage2 tune, peaking at 18.5psi. See above 6k shift everyday I drive it. Banjo filter bolt; New ones put in at 73k
. Remove the filter in the banjo bolts at 174K
. Running Amsoil SSO oil & Ea oil filters. My filter bolts was clean
. So I removed both filters in the banjo bolts & let the Duel by-pass, 2 micron filtration system take care of the small stuff.

Amsoil 0w-30 SSO and Amsoil Ea oil filter, Ea15k13 oil filter at 30k-73k .
At 73K, my filtration I use.http://legacygt.com/forums/showthrea...ons-81741.html
My oil system now is 7qt. I add 2-4qts over the 15k OCI.
Oil consummation hasn't change sense car was new.
Most off the shelf oil filter, filter down between 20 & 40 microns. Amsoil full-flow oil filter is 15 microns & Amsoil By-Pass oil filter is 2 microns.
This filtration system add 2qts. of oil to you motor. Which help keep the oil cooler.
In short, check you oil level often & top as needed. Use oil & filter that will protect for the OCI your running. OA's is the only way you know that your oil & filter is up for the challenge. After that IMO no OA's are needed.
