Oil Change Interval:
Typically every 5,000-7,500 miles or 6-12 months, depending on driving conditions and oil type used (consult manual for specifics).
Timing Belt Replacement:
For KL-ZE and KJ-ZEM engines, timing belt replacement is critical, typically recommended every 60,000-90,000 miles or 5-7 years. Failure can cause catastrophic engine damage.
Engine Oil Specification:
API SG, SH, or SJ certified, SAE 5W-30 or 5W-40 recommended (check manual for exact viscosity and capacity).

Supercharger Belt Kj Zem:
The supercharger belt on the KJ-ZEM engine is a known wear item and requires periodic inspection and replacement.
Valve Stem Seals:
Older KL-ZE engines may develop worn valve stem seals, leading to oil consumption and blue smoke on startup.
Automatic Transmission Performance:
Some transmissions may exhibit shifting issues or premature wear if not properly maintained with fluid changes.
