I'm with you, I oil any spot that moves (except) the bobbin, I do oil the bobbin casing, that holds the bobbin. I've got 1 Brother that I've had 11 yrs, works great, and another Brother, computerized, thats almost 4 yrs old now. I oil it to. My newest Brother dosent't have alot of oil holes, but I take out the screws, take semi-apart and clean and oil about once every 2-3 mos. Depends on how much I've been sewing. My machines really hum along nicely.
