Oil Change Interval Engine:
Typically every 5,000 miles or 6 months, but check manual for specific conditions and oil type.
Spark Plug Replacement Interval:
Check manual; often around 30,000-50,000 miles, depending on type (leading/trailing).
Fuel Filter Replacement Interval:
Check manual; typically around 30,000-60,000 miles.
Timing Belt Alternatives:
Rotary engines do not have timing belts; they use a chain or direct drive for the eccentric shaft.
Engine Oil Type Recommendation:
API SG/SH or SJ, ACEA A2/A3. Viscosity typically 10W-30 or 5W-30. Consult manual for exact specifications.
Transmission Fluid Type:
Mazda GL-5 75W-90 or equivalent synthetic gear oil.

Mazda GL-5 75W-90 or equivalent synthetic gear oil (LSD specific if applicable).
Coolant Type:
Ethylene Glycol based antifreeze, typically a 50/50 mix with distilled water.
Rotary Specific Concerns:
Apex seal wear, coolant seal failure (leading to overheating and engine damage), oil seal wear, carbon buildup.
Turbocharger Issues:
Overheating, oil leaks, wastegate issues on the sequential twin-turbo system.
Fuel System Concerns:
Clogged fuel injectors, weak fuel pump due to age.
