Oil Change Interval:
Every 3,000-5,000 miles or 3-6 months, depending on driving conditions (refer to manual for exact recommendation).
Timing Belt Replacement:
Recommended every 60,000-90,000 miles for the V6 (KL-DE) engine. The I4 (FS-DE) may have a timing chain or belt depending on specific variant, check manual.
Spark Plug Replacement:
Typically every 30,000-60,000 miles, depending on plug type (check manual).
Engine Oil Type:
API SG or higher, SAE 5W-30 or 10W-30 recommended (check manual for temperature variations).
Coolant Type:
Mazda Long Life Antifreeze/Coolant (blue) or equivalent ethylene glycol-based coolant, mixed 50/50 with distilled water.
Common V6 Issues:
Internal coolant leaks (intake manifold gaskets or cylinder head gaskets), oil leaks from valve cover gaskets, occasional distributor issues.
Common I4 Issues:
Less prone to major issues, but can experience oil leaks and exhaust manifold cracks.
Suspension Wear:
Worn control arm bushings, ball joints, and tie rod ends are common due to age and mileage.
Automatic Transmission Issues:
Some transmissions may exhibit slipping or harsh shifting with high mileage, often related to solenoid issues or fluid degradation.
