Synthamax Air Filters do not require
oil. Service air filter as needed by
cleaning with common non­petroleum all-purpose household
cleaner and water. Simple Green®,
Formula 409® or equivalent works
great. Apply cleaner to outside of air
filter and allow to soak. Then flush
filter clean from the inside out with a
garden hose and repeat steps if nec­essary. Do not apply high pressure
water or air to clean filter. Allow fil­ter to air dry and reinstall.
