Minsan, misleading talaga amoy ng langis sa makina. Pero kung amoy gas talaga, pachange oil and filter mo muna, delikado sa makina kung may halong gas na.

Gasoline in engine oil can be caused by:

1. mixture not being burned properly which would suggest spark plugs, coils or cables,
2. signs of blow-by; worn-out rings,

as suggested by the others.

Best is to have a competent mechanic check on it though.
