Common in rotary engines, requiring occasional decarbonizing procedures (e.g., 'Italian tune-up' or specific cleaning methods outlined in the manual).
|
|
Oil Consumption:
|
Rotary engines inherently consume some oil as part of their lubrication system. The manual details the expected consumption rate and checks.
|
|
Catalytic Converter:
|
Can be susceptible to damage from rich fuel mixtures or engine misfires.
