I've had an oilless 20 gal Craftsman for 10-12 years & it was used when I got it.
I've used it to sand blast, paint cars, run tools....yada. It still makes 120psi.
Still going like the Energized bunny.....getting to look kinda gnarly tho. Noisy sumbytch. To the right of the table saw. It don't get much love. ......
