Must have been a lot of "user" oiling errors out there, my JD 318 has ran fine for 27 years with an oiled foam pre-cleaner and normally I'd only clean it once a year. It would be caked with dirt at the end of the season but the paper filter remained clean and I'd usually go 3 or 4 years between changing it. When oiling the foam filter I'd always squeeze the crap out of it until no oil oozed out of it.
I'm hesitant to go with a dry filter because it seems like it would let a lot more dust through to the paper filter.
I wonder if the warranty would be voided on my X739 if I oiled the pre-filter?
