This spec doesn't apply to the car you selected.
Not yet checked against the factory manual for your car's year. It's verified in the 2003 Mazda MX-5 Miata Workshop Manual (electronic manual capture); 2005 Mazda MX-5 Miata Workshop Manual (electronic manual capture); later manuals may differ.
43–56 psi (295–392 kPa; 3.0–4.0 kgf/cm²) at 3,000 rpm295–392 kPa {3.0–4.0 kgf/cm², 43–56 psi} at 3,000 rpm
Factory manualTaken from a Mazda factory workshop manual, with page citation.
Procedure
Warm engine to normal operating temperature. Measure with a pressure gauge at the oil-pressure-switch port. Approximate running pressure; varies with viscosity and temperature. The actual 2005 engine technical-data table explicitly includes BP and BP WITH TC; the displayed setting applies to both.
Applies to
- 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.
- Verified in: 2003 Mazda MX-5 Miata Workshop Manual (electronic manual capture); 2005 Mazda MX-5 Miata Workshop Manual (electronic manual capture)
