# Engine oil pressure at 3,000 rpm (NB2 and Mazdaspeed)

Canonical URL: https://miatatorque.com/spec/engine-oil-pressure-3000rpm-nb2/

Applicability: NB 2001–2005 (BP-Z3) — Other years inferred from 2003 factory evidence.; NB 2004–2005 (BP-Z3-TURBO) — 2005 factory technical data explicitly includes BP WITH TC; 2004 inferred within MSM family.

Confidence: fsm

295–392 kPa {3.0–4.0 kgf/cm², 43–56 psi} at 3,000 rpm

Always confirm against your factory manual. Match every restriction and follow all stages and procedure notes. Disputed claims must not be automatically resolved. The complete record below preserves every printed unit, source claim and procedure.
