The more protection your engine has the better, however that does not mean saturate your filter, yu dont want oil getting in your engine. best way is to make sure your inner and outer filter are clean and dry good, then liberally spread oil on them and work it in good, then squeeze them good inside a paper towel to get all the excess oil off/out..If its really dusty you can wrap it in Vet-wrap which is a sticky self adhesive ace bandage, that will give you 3 layers of protection, so you can feel fresh and lively all day
