I went out to look for a new air filter, and yes of course, i found a load, but most of them said on the instructions (after i opened up the whole box and took everything out), that i needed to oil the air filter using "air filter oil", first time ive EVER heard of this... i mean i would have just put it straight on, as that would have made more sense to me, thinking it would have already been oiled, but then i went to the store clerk and he said he didnt know of air filter oil... so any ideas anyone? or did i just ask someone totally stupid? if so, prices or websites would be handy ;-) or can i just buy one and put it on, end of?
