The Mazda F2 is a 1,998 cc, inline‑six naturally aspirated petrol engine produced between 1988 and 1993. It features a single overhead camshaft (SOHC) and two valves per cylinder, delivering smooth, linear power ideal for executive sedans and coupes. Its cast-iron block and simple valvetrain prioritize durability and ease of maintenance for cost-conscious ownership.
Fitted primarily to the Mazda 929 (HD) and Eunos 500, the F2 was engineered for refined, comfortable cruising and light family use. Emissions compliance for its era was managed through a basic catalytic converter and carburetted fuel system, meeting Japanese 1988 emissions standards. Its character is defined by smooth, vibration-free operation rather than outright performance.
One documented area for attention is the distributor shaft bushing wear, which can cause timing inaccuracies and misfires. This issue, noted in Mazda Workshop Manual HD Series, is often linked to extended service intervals. Minor revisions were introduced during the production cycle to improve bushing material.

The inline-six configuration provides inherent smoothness but requires strict adherence to 10,000 km oil change intervals to prevent timing chain and distributor bushing wear. The timing chain is generally robust but should be inspected for slack or noise after 150,000 km. Using a quality mineral or semi-synthetic 10W-30/40 oil is recommended. The carburettor system requires periodic adjustment for optimal running. The engine's non-interference design offers peace of mind against timing component failure.

The Mazda F2 was used exclusively in Mazda's HD platform with longitudinal mounting. This engine received no major platform-specific adaptations during its production run, ensuring broad parts compatibility across model years. All specifications are documented in OEM workshop manuals.
The engine code 'F2' is stamped on the flat machined surface of the engine block, located on the front (timing chain) side near the oil filter (Mazda Workshop Manual HD Series). The 8th digit of the VIN for HD929 models with this engine is typically 'F'. Visually, it is identified by its inline-six configuration, single-barrel carburettor, and distributor-based ignition system mounted at the rear of the engine. No significant mid-production changes affect core part interchangeability.
The F2's primary reliability risk is distributor shaft bushing wear, with elevated incidence in vehicles subjected to extended service intervals. Mazda service data indicates a significant portion of high-mileage engines required distributor rebuilds, while general owner reports highlight the importance of regular ignition system maintenance. Preventative maintenance ensures this engine remains dependable.
