What to pay attention to
A minor service usually covers oil, filters and a general inspection, while a major service adds items such as spark plugs and additional fluids based on distance or time intervals.
Why an inspection may still be needed
Skipping items on a major service schedule can shorten component life even if the car currently drives normally, since some parts wear gradually rather than failing suddenly.
A sensible next step
Check your logbook or manufacturer schedule for the next due interval, and mention any symptoms so the correct service level can be quoted.
