🔧 Maintenance

Oil Change Interval:

Typically every 3,000-5,000 miles or 6 months, whichever comes first, especially important for rotary engines. The manual will provide specific intervals.

Spark Plug Replacement:

Due to the rotary engine's design, specific spark plugs (long reach, often two per rotor) require replacement at recommended intervals, e.g., 30,000-60,000 miles. The manual details exact types and intervals.

Air Filter Replacement:

Generally every 15,000-30,000 miles, or as needed based on driving conditions (dusty environments require more frequent changes).

Typically every 30,000-50,000 miles or 2-4 years.

Brake Fluid:

DOT 3 or DOT 4 brake fluid (check manual for exact specification and interchangeability).

Power Steering Fluid:

Mazda Genuine ATF (Automatic Transmission Fluid) or equivalent. (Refer to manual for specific type).

Apex Seal Wear:

A well-known concern with the Renesis engine is apex seal wear, leading to compression loss. Proper maintenance (oil changes, avoiding engine bogging, regular use) is key. The manual provides diagnostic methods for compression testing.

Catalytic Converter Clogging:

Can be prone to catalytic converter issues, especially if oil consumption is high or if the engine is regularly over-revved or not maintained properly.

Ignition System Reliability:

Ignition coils and spark plugs are critical. Premature failure can lead to misfires and rough running. The manual details correct replacement procedures and specifications.

Oil Consumption:

Rotary engines inherently consume some oil for lubrication. Monitoring and topping up the oil level is essential. The manual covers the oil metering system.

📚 Vehicle History
