I swapped a run-of-the-mill used NG into my 180k 4kq, changing
nothing but the clutch/front&rear seals//WP stuff. Compression
went from 128-135 to 185-195, same head/FI/manifolds/etc. Both
engines showed the same (ie, zero/zip/nada; no ridge ream, hone
marks still visible, etc) wear. FWIW, cold oil pressure is 80+
PSI (~5 bar); hot is 25/70 (2/5 bar) with 10-40 Amsoil.

YMMV, but I'm sure happy (with the "easy" performance).
