Description: FAB-1 is a highly advanced synthetic based formula for all oil type fabric and foam air filter elements. FAB-1 is a superior oil for stopping the passage of dirt, fine dust, water and other harmful elements. FAB-1’s super tacky polymer and co-polymer additives attract and hold onto virtually all fine dust particles. The water-proof base of FAB-1 resists moisture from passing through the filter. FAB-1 prevents oil “wash out” of the filter from carburetor fogging and offers the best protection for your engine, spark plugs, carburetor and air filter.
