Every car owner who has taken their car in for an oil change has been told that their engine air filter’s dirty.

Second, a visual inspection by your technician may determine that your filter it is visibly dirty and needs to be changed.

So between your owner’s manual and your technician’s inspection there’s really no guesswork involved.
