Regular Oil Change:
Every 3,700 miles (6,000 km) or 6 months, whichever comes first.
Air Filter Service:
Inspect every 7,500 miles (12,000 km); clean or replace as needed.
Spark Plug Replacement:
Replace every 7,500 miles (12,000 km) or inspect at 3,700 miles (6,000 km).
Brake Fluid Replacement:
Replace every 2 years, or as per manual recommendation (typically at 7,500 mile intervals as well).
Engine Oil Capacity:
3.2 US qt (3.0 L) with filter change; 2.9 US qt (2.7 L) without filter change.
Cooling System Capacity:

Common Complaints:
Some owners report occasional fueling hesitation, especially at lower RPMs, which can sometimes be addressed by ECU remapping or fuel system cleaning. Normal wear items like tires, brake pads, and battery are expected. The shaft drive system is generally reliable but requires periodic fluid changes.
Preventative Measures:
Adhering to the recommended service intervals outlined in the manual is crucial for longevity and preventing premature wear.
