Fuel Tank Capacity:
6.0 gallons (22.7 L)
Engine Oil Change:
Every 5,000 miles (8,000 km) or 12 months, whichever comes first.
Primary Chain Tensioner Inspection:
Check at 10,000 miles (16,000 km) and every 10,000 miles thereafter. Hydraulic tensioner upgrade may be considered.
Transmission Oil Change:
Every 10,000 miles (16,000 km).

Primary Chain Tensioner:
Early models (pre-2007) had hydraulic tensioners that could fail. 2012 models use a revised tensioner, but inspection is still recommended. Upgrade to a more robust aftermarket tensioner is common.
Cam Chain Tensioners:
Similar to the primary, the cam chain tensioners can wear. Regular inspection and potential replacement with upgraded components are advisable.
Exhaust Leaks:
Leaking exhaust gaskets can occur, leading to ticking noises. Proper tightening and gasket replacement are solutions.
Idle Air Control Motor:
Can sometimes cause rough idling or stalling issues in EFI systems.
Battery Drain:
Potential for parasitic draw if electrical accessories are not properly wired or if the charging system is weak.
