Oil lubed.
Just cracked the box and went through the break-in procedure. Tried my framer and finish nailers and it works great. Mobility is really good.
One negative: this sucker is LOUD! Unfortunately I was looking for a quieter type(hence the oil lube choice). It has a removable console. I guess I could wheel it as far away as I can go with a good extension cord and the distance will help with the noise.
